RIACTION COILOVERS
GT-1: LINEAR COILOVERS
Riaction GT-1 Linear Coilover Kit is the most popular coilover system that we offer. These adjustable coilovers offer a height-adjustable body with tunable rebound damping for quick changes in ride quality and driving characteristics.
The linear valved kit is great for street driving, canyon carving, and the occasional track day.
GT-2: LINEAR 2-WAY
The Riaction GT-2 Linear 2-Way Coilover Kit builds on the GT-1 platform with added compression adjustability via external reservoirs. It shares the same height-adjustable body and rebound control while offering improved heat management and advanced tuning capability.
This 2-way kit is perfect for serious track drivers and those who want more suspension control—even on the street.
GP-1: DIGRESSIVE
The Riaction GP-1 Digressive Coilover Kit offers improved low-speed control over linear valving. Resistance ramps up quickly at lower shaft speeds, then tapers for a controlled yet comfortable ride during higher-speed inputs.
Ideal for street driving, canyon carving, and track days with an emphasis on chassis stability and smooth compliance.
GP-2: DIGRESSIVE 2-WAY
The Riaction GP-2 Digressive 2-Way Coilover Kit features rebound and compression adjustability through external reservoirs. With digressive valving and increased fluid capacity, this kit provides confident feedback and improved stability.
Perfect for enthusiasts seeking total control on the street, through the canyons, or at the track.
Let customers speak for us
Haven’t gotten a chance to install yet. The overall product is amazing. The quality is top notch. I enjoyed calling reaction when I had questions about spring rates and what kind of dampening I should start with. The team over there at riaction is amazing. Any question you have about your coil over, they will be able to answer! Can’t wait to get these babies on
The Riaction RZ34 coilovers fit great and made the ride height just how I wanted it. The ability to chose firm or soft ride quality was a big plus.
Great product, great customer service. Happy to work with them in the future
yes the PORSCHE 944 (85.5-86 NA) EARLY OFFSET fit the 87-88 924s with no problems. install and adjustment was straight forward, great design.
Great Quality socks for my recently purchased Riaction coilovers.
Ive had these coilovers for 6 years solid, reason for replacement hit a major pothole. Great product.Order was easy and delivered earlier than promised.
Perfect fitment, High quality, best riding coilovers I have ever driven on. Highly recommend
Installed these for about a year now. Its been nothing but amazing and great.
Great product. Prompt response by the Riaction team to any questions I had before purchasing. Quick shipping time. Quality feel and look to the coil-overs once I got them in hand. 1 week after install; factory 12k/8k spring rate and no complaints. Very excited to experience how the product performs down the road. So far so good.
So much better then the stock mount, In have heard of some of the factory mounts breaking. Not with these billet aluminum ones.
Love the coilovers, ride quality is a amazing for coilovers. A little stiffer then stock, but a great ride even over out not so great country roads. Handles the bumps like a champ. Definitely go with the GP-1's make a difference with the ride quality. Handles so much better then stock, even with ECS equipped. Was an easy install, and was not difficult to adjust even for a first timer like myself. Love how I can dial in my ride hight, and for every day driving have my dampeners sent to 2, can't wait to hit the track and see how handles (4000lb car). Reaction did an awesome job getting my product to me, in one week ordered, shipped and delivered. Was surprised on how fast they showed up. Great build quality, looking for many years of use.
Best customer service in a time where customer service means everything! Seriously, the best experience I have ever had. Im a loyal customer.
