Riaction Coilovers

Riaction's GT-1 is their most popular coilover and the kit most owners are looking at when they first discover the brand. It uses a monotube shock design with 32 clicks of rebound damping adjustment and independent ride height adjustment, meaning you can set your ride height without affecting spring preload. The linear valving gives a predictable, consistent feel across the adjustment range, which is why the GT-1 gets consistently good reviews from daily drivers who want a coilover that is comfortable on low settings and noticeably better in corners than stock regardless of where they set the damping.

One thing worth knowing about Riaction: the lowest damping setting on the GT-1 is genuinely usable for daily driving. Owner reviews consistently describe the soft end of the range as smooth and comfortable on highways, with the ability to stiffen it up for back roads or track days. That usable range is one of the main reasons Riaction has built a following on Honda and Acura platforms where daily drivability matters as much as handling improvement.

Riaction GT-1 vs GT-2: What is the Difference?

GT-1 (most popular, 32-way rebound adjustment)

The GT-1 is Riaction's entry coilover and their most widely sold kit. It has 32 clicks of rebound damping adjustment and independent ride height control. Linear valving makes the adjustment range easy to use since the damping response is consistent and predictable across all 32 settings. Most owners find their preferred daily setting within the first week and occasionally stiffen it for more spirited driving. Fully rebuildable with a 2-year warranty and a lifetime labor warranty meaning Riaction services the coilovers for free after the initial warranty period, you just pay for parts.

• 32-way rebound damping adjustment
• Independent ride height adjustment
• Monotube shock design
• Fully rebuildable, 2-year warranty plus lifetime labor warranty
• Swift spring upgrade available on most applications
• Best for: daily drivers, street builds, canyon driving, and occasional track use

GT-2 (2-way independent compression and rebound adjustment)

The GT-2 builds on the GT-1 platform with added compression adjustability via external reservoirs. The external reservoirs also increase fluid volume which helps manage heat under sustained hard driving. For drivers who want to tune compression and rebound independently for a specific track or road setup, the GT-2 gives that level of control without moving to a full race coilover.

• Independent compression and rebound adjustment
• External reservoirs for improved heat management
• Same height adjustment and monotube design as GT-1
• Best for: track use, autocross, and drivers who want maximum tuning flexibility

Frequently asked questions

Are Riaction coilovers good?

Yes, particularly for the price range. The GT-1's monotube design, 32-way damping adjustment, and independent ride height control are features you typically find on more expensive kits. Owner reviews across Honda, Acura, Toyota, and Subaru platforms consistently describe good ride quality at soft settings and a meaningful improvement in handling over stock. The lifetime labor warranty is a standout perk that most competing brands do not offer. Riaction is a strong recommendation for daily-driven street builds where budget matters but build quality cannot be compromised.

What does 32-way adjustable damping mean?

It means the damping stiffness can be adjusted across 32 individual increments by turning a dial on the shock body. More adjustment range means more ability to dial in the exact feel you want. On the GT-1, all 32 clicks adjust rebound damping. On the GT-2, compression and rebound are adjustable independently. Most owners find their preferred daily setting in the softer half of the range and step it up for back roads or track days.

What is independent ride height adjustment?

Independent ride height adjustment means you can change your ride height without affecting spring preload. On coilovers without this feature, lowering the car also changes the spring load which can affect ride quality. On Riaction kits, the spring perch and ride height adjustment are separated so you can dial in your stance without compromising how the spring behaves.

Does Riaction offer a warranty?

Yes. Riaction coilovers come with a 2-year warranty against manufacturing defects. They also offer a lifetime labor warranty, which means after the initial 2-year period they will service and rebuild your coilovers at no labor cost, you only pay for any replacement parts needed. As an authorized Riaction dealer, purchases from Redline360 ensure your warranty is fully valid.

How much do Riaction coilovers lower your car?

Most Riaction kits lower the vehicle between 1 and 3 inches from stock ride height. The exact range varies by vehicle. Riaction coilovers are designed as lowering coilovers and cannot be set to OEM ride height or higher. Check the specific product listing for your vehicle's adjustment range before ordering.

Are Riaction coilovers rebuildable?

Yes. All Riaction coilovers are fully rebuildable. You can replace individual components like seals, springs, and internal parts rather than replacing the entire kit when something wears out. This is one of the reasons the lifetime labor warranty is meaningful, Riaction is willing to back up the rebuildable design with ongoing service support.
