Race Tech Coil Spring

Race Tech Coil Springs: Precision-Engineered for Real Performance

When it comes to suspension tuning, the coil spring is the foundation everything else is built upon. Too soft and your chassis wallows; too stiff and you lose traction. Race Tech has spent over three decades obsessing over this balance, and their coil spring lineup reflects that depth of expertise in every wound coil.

The RT Hi-Performance Spring Advantage

Race Tech Hi-Performance Fork and Shock Springs are engineered to deliver the highest stiffness-to-mass ratio in the industry — meaning they are lightweight for their particular spring rate. That matters on a motorcycle or powersports machine where unsprung weight directly affects handling response and rider feel.

What separates Race Tech springs from generic alternatives is the level of manufacturing precision behind each unit. RT Hi-Performance Springs feature extremely accurate rates and are heat-treated, shot-peened, and preset so they cannot sack out. Most manufacturers hold their spring rates within 5% of the listed rate, which means a spring marked 5.0 kg/mm could actually measure as a 4.75 or even a 5.25 — making two springs with different labels potentially the same rate. Race Tech holds its springs to a far tighter standard, so the rate you select is the rate you get.

Spring Conversion System: From Air Forks to Coil

One of Race Tech's most compelling coil spring solutions is their Spring Conversion System (SCS). The Race Tech Spring Conversion System transforms air spring forks found on the Kawasaki KX450, Suzuki RMZ450, Honda CRF250, and KTM/Husqvarna WP AER 43 and 48 to a SFF (single function fork) style coil spring setup. Most riders prefer the feel of a coil spring over an air spring , and the SCS makes that conversion straightforward. Not only is the performance improved, but the RT SCS is a "set it and forget it" solution — no need to check pressures before each ride, and installation is easy enough to be called a drop-in.

Custom Spring Collars and Special Fitments

Race Tech manufactures a large selection of Shock Spring Collars to fit their standard springs to unusual applications, and lowered suspension quite often requires shorter springs. They can modify existing designs to shorten them, allowing a high degree of flexibility for special fitments. Whether you're building a race-spec machine or simply dialing in a street bike for your weight and riding style, Race Tech's broad catalog of spring rates and diameters means there's a solution for nearly every application.

The Right Spring Rate Makes All the Difference

Race Tech provides suspension enhancement products for all types of motorcycles, as well as ATVs and snowmobiles , and their spring selection spans the full range of these platforms. Selecting the correct spring rate for your weight and riding discipline is critical — proper weight springs (and tuning/valving) will make a world of difference in your riding, with the bike feeling more planted in corners and on uneven terrain. Race Tech's online Product Search tool helps riders identify the correct spring rate by model, rider weight, and application, taking the guesswork out of the process.
