MRTC-BD8SV Compatible Progressive Shock Spring - Yokomo RP-077 for Touring Cars  [RP-077]

Progressive shock spring for 1/10 touring cars

The Yokomo RP-077 is a progressive shock spring made for 1/10 on-road touring car dampers. The coil spacing varies along the length so the spring gives a softer first stage and increases stiffness deeper into compression, helping control small bump response and resisting bottoming on larger compressions.

The spring has a black finish and the spring rate is laser engraved on the end for quick identification during setup. It is supplied in a protective plastic case for safe storage and transport.

Fitting is standard: install the spring inside the damper assembly, set the preload and check damper travel after replacement, then assess handling changes across several lap runs rather than trusting a single pass.
