The RP-083PU is an RC-scale front off-road spring intended for high-traction indoor surfaces such as carpet and astro turf. The purple RP Ultra finish provides fast visual confirmation when sorting springs in the pits.
Engineering emphasis is on predictable front-end performance on carpet surfaces. Yokomo adjusted material selection and manufacturing steps to improve compression consistency for front suspension applications in off-road setups.
Installation notes: swap the front springs for RP-083PU units as a direct replacement, checking spring orientation and perch seating align with your chassis guidance. Standard hex drivers are sufficient for the task; inspect spring seats and retainers for wear as part of the process.
Tuning purpose: these springs are used to shift front response—affecting braking dive, rebound after jumps, and roll through corners on carpet or astro surfaces. Use alongside measured shock oil and ride-height tweaks to reach the intended front-end balance without altering shock pistons or bodies.
