This front shock spring, supplied as Yokomo BM-S1295, is intended for use with big-bore X-shock assemblies on B-MAX off-road platforms. It provides a direct spring replacement to tune or restore front suspension characteristics without changing the rest of the shock unit.
Compatibility applies only to the listed B-MAX chassis codes: B-MAX2MR2, B-MAX2MR3, B-MAX2RS, B-MAX43G and B-MAX43GF. Confirm your shock assembly is the big-bore X-shock type prior to installation.
Fitting advice: carry out normal shock disassembly steps, slip the spring over the shaft, adjust preload at the collar until the desired ride height is reached, then reassemble making sure the spring is seated correctly. Standard RC maintenance tools are sufficient.
Handling impact: fitting this spring will change front compliance and feedback, which affects steering behaviour and weight transfer during jumps. For best results, adjust damper oil and piston selection alongside the spring swap to suit the surface conditions.
