Yokomo BM-S1295 front shock spring for B-MAX2/B-MAX4 big-bore X-shock  [BM-S1295]

Front shock spring for B-MAX

This is an RC-scale front shock spring supplied under Yokomo model BM-S1295 intended to fit big-bore X-shock assemblies used on B-MAX off-road platforms. The part is a direct replacement spring component that focuses on restoring or adjusting front suspension response without altering other shock hardware.

Compatibility is limited to the listed B-MAX chassis series and specific codes: B-MAX2MR2, B-MAX2MR3, B-MAX2RS, B-MAX43G, and B-MAX43GF. Check your shock assembly model to confirm it uses a big-bore X-shock style before fitting this spring.

Installation notes: use standard RC shock disassembly procedures, slide the spring over the shock shaft, set preload by adjusting the collar to the desired ride height, and reassemble ensuring the spring seats squarely. No special tools are required beyond common RC maintenance tools and a clean workspace.

Tuning role: swapping to this spring affects front-end compliance and feedback, so expect changes in steering bite and weight transfer during jumps and landings. Combine spring changes with damper oil and piston tuning to achieve balanced handling on loose or mixed off-road surfaces.
