HPI Baja Rear 208mm Adjustable Alloy Spring Damper - BJ208R/A by GPM  [BJ208R/A]

208mm rear shock for HPI Baja tuning

This rear spring damper is built for HPI Baja setups and carries the model number BJ208R/A. It pairs a 208mm shock body with an aluminum alloy construction, silicone dust covers and alloy ball ends to give a rugged, serviceable replacement or upgrade for rear suspension on Baja-style RC buggies.

Role in setup and tuning: the damper provides adjustable spring preload and flexible mounting geometry so you can tune rear behaviour under acceleration, on landings and across rough ground. Use spring swaps, different shock oils and alternative mounting positions to refine ride height, rebound feel and roll control.

Fitting notes: this unit uses a 208mm mounting length. Typical installation involves removing the original rear shock, transferring or swapping springs, and fastening the alloy ball ends to the stock shock mounts using the vehicle's existing hardware. Confirm correct ball end orientation and thread engagement and ensure silicone covers are seated before running.

For tuners and hobbyists using HPI Baja platforms, the BJ208R/A rear damper is a simple, durable replacement or upgrade that adds basic adjustability without altering suspension geometry.
