HPI Racing BB RC Shock Spring Red 86.1gm - HPI109811

The HPI Racing HPI109811 BB Shock Spring in red is a replacement suspension spring designed for use with compatible HPI Racing shock absorbers. Rated at 86.1gm spring rate, this red-coded spring gives you a known, consistent stiffness value when rebuilding or tuning your RC car's suspension. Shock springs are a key part of suspension setup — swapping to a stiffer or softer spring changes how the car responds to bumps, jumps, and cornering, making this a useful spare to have on hand for maintenance or basic suspension tuning.
