A racing spring has one job the street never asks of it: hold an exact spring rate through extreme heat, cyclic loads, and G-forces, race after race, without sagging. For over a decade, Anderson Quality Spring (AQS) has handled motorsport springs manufacturing for aftermarket suspension brands and race teams, and we manufacture custom fork springs, shock springs, pressure springs, top-out springs, and the wire form parts that go with them.
Motorsports suspension parts leave no margin for a spring that drifts off rate. Building them takes deep knowledge of raw material, stress limits, mating-part interactions, and manufacturing processes, and AQS has earned it over a decade in the racing industry. We manufacture racing springs to the rate and performance a full race weekend demands, and the ones after it.
Winning suspension setups start with springs that do exactly what the data says they will. AQS keeps the processes that control spring quality in-house — CNC coiling and forming, shot peening, labeling, and packaging — with presetting where a setup’s spec calls for it. For finishing such as powder coating, and any capability we do not hold in-house, we work through our network of certified vendors at the same standard of quality and performance, so you still get a finished racing spring.
AQS controls motorsport spring manufacturing from wire to finished, packaged part. In-house CNC coiling and forming and shot peening produce racing springs to tight, repeatable tolerances and consistent quality, with presetting where a spec calls for it, and our engineering team supports you from the quote through production.
Racing springs start with high-tensile alloy steel chosen for elastic limit and fatigue life. AQS works in chrome silicon and chrome-vanadium alloy steels, the suspension-spring materials that hold a higher spring rate under heat and repeated compression.
Corrosion-resistant coatings, applied through our certified finishing partners, add durability and performance without the unsprung weight a race car cannot afford, because in motorsports the priority is performance, not comfort.
Motorsports springs face extreme cyclic loads and higher temperatures than standard automotive springs ever see. AQS shot peens for fatigue resistance, and presets through repeated compression to stabilize the spring under load where a setup’s spec calls for it.
Stress-relief heat treatment is applied where the material calls for it, so the racing spring holds the performance the setup specifies through its race hours before a rebuild.
Predictable handling depends on a consistent spring rate from the first lap to the last. AQS manufactures racing springs to a tight, repeatable rate, and builds dual-rate and progressive designs when a setup needs a softer initial motion and a higher rate deeper in travel.
That consistency keeps a car’s balance repeatable and a driver’s inputs trustworthy. Our springs work with the shock absorbers to control weight transfer, so the setup holds its performance.

AQS manufactures the full range of motorsport spring types and wire forms, including technical compression springs, extension springs, torsion springs, and custom wire forms, alongside our core suspension work. We produce racing springs and parts for a wide range of motorsports assemblies, including but not limited to:
Every racing discipline loads a spring differently, and AQS manufactures racing springs to the spec of the specific car and class they run in, not to a generic rate. From formula cars to stock cars, the racing applications below are representative of the motorsports industry work AQS supports.
Motorcycle road racing and motocross rely on fork springs and shock springs tuned to the rider and the track. AQS is a longtime supplier of custom fork springs and shock springs, made to the exact rate a suspension tuner specifies for the machine and the surface.
AQS brings added value through in-house engineering. We offer preliminary feedback during quoting and in-depth consultations for our customers’ NPI project managers and design engineers, working from a blueprint, reverse engineering a sample, or consulting on a new spring or wire form design.
For over a decade, AQS has built supplier partnerships across the motorsports industry, including BBR Motorsports, GP Suspension, Enzo Racing, Vanasche Motorsports, and PR2 Racing. Our inventory management integrates with customers’ MRP systems, and we supply both current-production parts and late-lifecycle service and warranty parts. AQS also manufactures related springs and wire forms for the automotive industry.
