This Yokomo BM-S1295 front shock spring is made to fit big-bore X-shock units found on B-MAX off-road chassis. It serves as a direct replacement to tune or restore front suspension feel without replacing other shock components.
Compatibility is limited to the specified B-MAX chassis codes: B-MAX2MR2, B-MAX2MR3, B-MAX2RS, B-MAX43G, and B-MAX43GF. Confirm your shock uses the big-bore X-shock format before installing this spring.
Installation notes: follow standard shock service steps, slide the spring onto the shock shaft, set preload with the collar to reach the desired ride height, and reassemble ensuring the spring seats evenly. No specialized tools are required beyond basic RC maintenance tools and a tidy workspace.
Tuning role: swapping to this spring will change front compliance and steering feedback, so expect altered steering bite and weight transfer on landings. Combine spring swaps with damper oil and piston adjustments to achieve balanced handling on loose or mixed off-road surfaces.
