Overview
Get rally-spec front suspension tuning on your Arrma Grom with the Hot Racing 38mm Progressive Rate RS Spring Set. This complete tuning kit features three progressive-rate spring tensions, giving you the flexibility to dial in front-end traction, jump landing behavior, and chassis balance for any track surface.
Progressive-rate springs deliver the best of both worlds — soft initial compression for compliant small-bump absorption, plus stiffer mid-to-high compression rates for excellent jump landing control and high-load corner stability. A must-have tuning kit for serious Grom drivers.
Key Features
- Progressive-rate spring design
- Three spring rates: soft (chrome), medium (black), firm (gold)
