Are KYB Excel-G shocks good — and better than OEM?
Yes, for most worn-out daily drivers. KYB's Excel-G is an OEM-replacement-plus shock that delivers roughly 115-125% of original damping force — firmer and more controlled than a tired factory shock, without being harsh. In our real-world test it cut nose-dive under braking, killed highway "float", and held a loaded vehicle composed. It's not a track or hardcore off-road shock, but for restoring (and slightly sharpening) a normal car's ride, it's the smart-money pick.
The wrong shock absorbers don't just waste money — they turn a comfortable car into a jarring nightmare. Every pothole jolts you, every highway cruise feels unstable, and that fear stops many people from upgrading.
KYB Excel-G shocks (Kayaba's flagship aftermarket line) are globally trusted as an OEM-replacement-plus upgrade. They restore and slightly enhance your vehicle's original handling with 115-125% more damping force. Most drivers with worn shocks get a firmer, more controlled ride that isn't excessively harsh — but will it feel "too stiff"? We answer that with real data.
This definitive 2026 review compares the Excel-G directly against stock OEM ride quality, shares hands-on test results, and analyses durability data to help you decide with confidence.
Why OEM Shocks Fail
The Invisible Decline
Your car's original shocks don't fail overnight — they degrade slowly, which tricks you into accepting a poor ride. But the impact on safety and performance is real.
This gradual loss happens over tens of thousands of kilometres. You get used to extra bounce and sway, and you don't realise what you've lost.
Critical Safety Data
Studies show shock absorbers lose significant effectiveness in just 80,000 km (50,000 miles).
The National Highway Traffic Safety Administration (NHTSA) notes that worn suspension parts increase stopping distance — especially on uneven surfaces, where it could make the difference in emergency braking.
Is Your Car Warning You?
Watch for these three clear signs it's time for replacement:
- The "bounce test" fails: push down on a corner of your car. If it rocks or bounces more than 1-2 times, you've lost damping control.
- Nose dives and body roll: the front dips too much during braking, or the body leans heavily in corners and feels unstable.
- Uneven tyre wear: you see "cupping" or scalloping patterns on your tyres — a classic sign the tyre isn't held firmly against the road.
KYB Excel-G vs. OEM
The 125% Damping Difference
This is the most misunderstood specification. It's not about brutal stiffness — it's about control.
Think of pushing a screen door with a weak closer (worn OEM) versus a new, properly calibrated one (Excel-G). The Excel-G simply resists unwanted motion better, controlling bounce and roll more effectively.
"115-125% damping" means the shock provides 15-25% more control force than a brand-new original part. It's a calculated enhancement, not a race-car modification.
Direct Feature Comparison
Here's how the two options compare in feel and function — this table clarifies where the Excel-G stands as an upgrade.
| Feature | Standard OEM Shocks | KYB Excel-G Shocks |
|---|---|---|
| Damping design | Calibrated for 100% of original spec (soft, comfort focus) | Calibrated for 115-125% of original spec (control focus) |
| Ride feel | Often soft, sometimes "floaty" on highways | Often firm, planted and controlled |
| Handling response | Slower steering response, more body roll | Quicker steering response, reduced body roll in corners |
| Best for | Maximum comfort on smooth roads, daily commuting | Better handling, stability when loaded or towing |
| Value | The baseline standard | OEM-plus performance at an affordable price |
The Bottom Line on Feel
Switching from worn-out OEM shocks to new Excel-G units feels like night and day — vehicle stability and confidence improve dramatically.
If you switched from new OEM shocks to new Excel-G shocks, you'd feel a deliberate firming of the ride. Road imperfections come through more clearly, but the car feels much more secure and responsive.
Our 2026 Real-World Test
Is the Ride Too Harsh?
We moved beyond forum theories to give you real answers. We installed a full set of KYB Excel-G shocks on our test vehicle — a 2018 Toyota Camry with 113,000 km (70,000 miles) on its original, tired suspension.
We used Front #341744 and Rear #344353, common replacements for this platform, following the manufacturer's service manual precisely for every step.
A Critical Installation Detail
During front strut assembly, we paid attention to a commonly overlooked detail: we torqued the front strut top mount-to-body nuts precisely to 46 Nm (34 ft-lb).
Over-torquing is a frequent DIY mistake — it can bind the strut mount bearing, causing noise or early failure. We got this exact specification from Toyota's Technical Information System (TIS), ensuring an installation matching factory standards.
The Cold Morning Feel
Our first test drive was on a chilly 7°C (45°F) morning. For the first five to ten minutes, the ride was noticeably firm over sharp road imperfections like expansion joints.
This is expected. Colder shock fluid is more viscous, providing higher initial damping. As the shocks worked and the fluid warmed, the ride settled and became more compliant.
City vs. Highway Performance
In stop-and-go city driving, the car felt more athletic. The pronounced "nose dive" during moderate braking reduced by what felt like at least 50%, staying much flatter and more composed.
On the highway, the difference was profound — the vehicle's behaviour changed from passive to engaged.
Our takeaway: the "floaty" sensation on long, sweeping highway curves was completely gone. The car felt planted and secure, resisting unsettling movements from crosswinds or passing trucks. This is where the 115% damping on the rear shocks truly shines — it provides stability where it matters most.
The Loaded Vehicle Test
The final test was for practicality. We added two adult passengers to the back seat and luggage in the boot — about 180 kg (400 lb) of extra weight.
With old OEM shocks, this load would have made the rear feel soft and saggy, risking bottoming out on large bumps.
The Excel-G shocks handled the weight with minimal compression. Ride height stayed stable, and the vehicle cleared a particularly nasty railway crossing without the rear suspension crashing into the bump stops. This is huge for families or anyone who frequently carries cargo.
Durability and Lifespan
What Owners Really Say
We analysed hundreds of owner experiences from communities like Reddit's r/CarTalk and model-specific forums for Toyota, Honda and Ford. The consensus is overwhelmingly positive on longevity:
- Pro: KYB Excel-G shocks are widely praised for durability, frequently lasting well over 97,000 km (60,000 miles) and easily outlasting cheaper "white-box" aftermarket brands.
- Con: the few legitimate negative reports almost always trace back to two things — incorrect installation, or failing to replace old, worn-out mounts, boots and bushings at the same time.
The Importance of Synergy
A part's lifespan ties to its surrounding components — this isn't just opinion, it's mechanical reality.
A key finding from a Car and Driver technical deep-dive on suspension is that component synergy is critical: a new shock's performance and lifespan are directly compromised by worn parts like mounts and bushings that fail to support it properly.
Always replace strut mounts and bellows boots when installing new struts. It's the only way to guarantee the full performance and lifespan of your investment.
Built to OEM-Plus Standards
KYB isn't just an aftermarket company — it's one of the world's largest Tier 1 suppliers of shock absorbers directly to vehicle manufacturers.
The Excel-G line is made in the same factories, held to the same (if not stricter) quality control as the parts KYB supplies to Toyota, Honda and others. This direct link to original-equipment manufacturing ensures consistent performance and an exceptionally low defect rate.
OEA vs OEM: What You're Actually Buying
One distinction trips up a lot of buyers: OEM versus OEA. OEM (Original Equipment Manufacturer) parts are what the car left the factory with. OEA — Original Equipment Aftermarket — means a part engineered to original-equipment standards but sold through the aftermarket, which is exactly what the Excel-G is. You get OE-grade engineering without paying dealer prices.
That engineering shows up in the details. The Excel-G uses multi-lip oil seals to guard against the leaks that kill twin-tube shocks, hard-chromed piston rods that resist pitting and wear, and seamless cylinder construction for consistent damping over the shock's life. Suspension specialists point to the main piston seal as the usual first failure point on twin-tube designs — KYB's sealing technology is built specifically to address it.
When to Consider Alternatives
Is Excel-G Always the Answer?
For about 90% of daily drivers, the KYB Excel-G strikes the perfect balance of control, comfort and value.
But what if your needs are more extreme? If you tow heavily on Friday and then demand maximum articulation for off-roading on Saturday, a single fixed-rate shock is always a compromise.
The Power of Adjustability
This is where adjustable shock absorbers come in. They offer multiple damping settings, typically changed with a simple dial or knob, letting you transform your vehicle's handling profile from soft to firm on demand.
A No-Compromise Solution
For drivers who demand this level of control — especially on highly capable platforms like the GWM Tank 300 — an adjustable setup is the ultimate upgrade. The GWM Tank 300 Adjustable Shock Absorbers from EVparts4x4 let you manually tune both compression and rebound damping.
That means you can dial in a comfortable, compliant highway ride for the commute, then switch with a few clicks to a firm, ultra-responsive setup for tough trails or heavy loads. It's the definitive no-compromise solution for owners who use their vehicle to its full potential.
The Final Verdict for 2026
Is the KYB Excel-G Right for You?
After our in-depth testing, data analysis and community-feedback review, the verdict is in: the KYB Excel-G isn't just a replacement part — it's a calculated, intelligent upgrade.
It directly addresses the weaknesses of worn factory suspension and adds a tangible layer of safety and driver confidence.
Who Should Buy Them?
You SHOULD buy KYB Excel-G shocks if:
- Your current shocks have over 80,000 km (50,000 miles) and feel soft, bouncy or unstable.
- You want to restore and slightly improve your car's original handling and stability.
- You value a "planted" highway feel and reduced body roll in corners.
- You're after the best balance of performance, longevity and price.
Who Should Reconsider?
You should CONSIDER alternatives if:
- You prioritise a soft, cloud-like ride above all else (stick with new OEM parts).
- You do serious off-roading or carry highly variable heavy loads (look into adjustable shocks like the GWM Tank 300 set above).
- You're a track-day enthusiast who needs aggressive, high-performance damping for competition.
The Bottom Line
For the vast majority of drivers, the 2026 KYB Excel-G remains the definitive "smart money" choice. It solves the core problem of worn-out shocks while delivering a noticeable improvement in control and safety — all without a punishingly stiff or uncomfortable ride. It's the true king of OEM-plus performance.
Frequently Asked Questions
Are KYB Excel-G shocks any good?
Yes. KYB is a Tier 1 original-equipment supplier, and the Excel-G is its flagship aftermarket shock, built in the same factories as the OEM parts it supplies to Toyota, Honda and Subaru. Owners routinely report reliable service well past 97,000 km (60,000 miles). For restoring a worn daily driver to a firm, controlled ride, it's one of the best-value choices available.
Are KYB Excel-G shocks better than OEM?
They're an OEM-replacement-plus: calibrated for roughly 115-125% of the original damping force, so they restore lost control and slightly sharpen handling versus a worn factory shock. Against brand-new OEM, expect a deliberately firmer, more planted ride. It's an upgrade in control, not a downgrade in comfort — though it's not as soft as some "floaty" factory tunes.
KYB Excel-G vs Bilstein B4 — which is better?
Both are comfort-focused, OEM-replacement-plus shocks. The KYB Excel-G is a twin-tube design that's excellent value and widely available; the Bilstein B4 is also twin-tube and aimed at restoring original ride feel, often at a higher price. For most daily drivers either is a strong choice — see our Bilstein B4 vs B6 guide for the full breakdown.
Is the KYB Excel-G ride too stiff or harsh?
For most worn-shock replacements, no. It's firmer than a tired factory shock but not punishing. In our test it felt firmest in the first 5-10 minutes on a cold morning (thicker fluid), then settled as it warmed. If you want a soft, cloud-like ride above all else, a new OEM shock is softer; if you want control, the Excel-G is the better balance.
How long do KYB Excel-G shocks last?
Owners commonly report well over 97,000 km (60,000 miles) of reliable service, often more. Lifespan depends heavily on fitting fresh strut mounts, boots and bushings at the same time — most early failures trace back to worn surrounding parts rather than the shock itself.
Is KYB the same as Kayaba?
Yes — KYB is the brand name of Kayaba, the Japanese manufacturer. "Kayaba Excel-G" and "KYB Excel-G" are the same shock.
What's the difference between OEA and OEM shocks?
OEM (Original Equipment Manufacturer) shocks are the exact parts your car was built with. OEA (Original Equipment Aftermarket) shocks, like the KYB Excel-G, are engineered to original-equipment standards but sold through the aftermarket — so you get OE-grade build quality (multi-lip oil seals, hard-chromed piston rods, seamless cylinders) without dealer pricing. For most owners, a quality OEA shock matches or slightly improves on the original.
