Kyosho XGS035 Big Bore Rear Spring M-Soft (2)

Kyosho XGS035 is a genuine pair of medium-soft rate rear shock springs for Kyosho's big bore dampers. These are the long LL-size springs at roughly 46mm, produced for Kyosho's X-Gear spring program with consistent, matched rates so both rear corners behave identically. Spring rate is one of the most powerful tuning tools on an off-road chassis: a medium-soft rear spring increases rear traction and chassis roll, helping the truck hook up and stay composed on low-grip and bumpy surfaces.

These springs are intended for the Kyosho Ultima RT5, SC, and DB vehicles equipped with the W5305V big bore shock set, where they install as a direct fit tuning option over the kit springs. They also slot into the broader XGS spring lineup, so you can test rates back to back and log what works on your local track. Package includes two matched rear springs, one for each rear shock.
