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

Rear 208mm adjustable shock for HPI Baja

This is an RC-scale rear spring damper designed for HPI Baja applications, supplied by GPM as model BJ208R/A. The unit pairs a 208mm shock body with an aluminum alloy build, silicone dust covers and alloy ball ends to provide a durable, serviceable replacement for worn or upgrade rear suspension components on Baja-style remote‑control buggies.

Intended function and tuning role: the damper serves as a tunable element within the vehicle suspension, allowing adjustment of spring preload and damper mounting geometry to alter rear-end behaviour during acceleration, jumps and rough terrain. Use it to refine ride height, rebound characteristics and roll control in coordination with springs, shock oil and mounting positions.

Installation notes: this part is an RC accessory sized for 208mm mounting length. Standard installation requires removing the original rear shock, transferring springs if desired, and securing the alloy ball ends to the existing shock mounts with the vehicle's original fasteners. Check ball end orientation and thread engagement, and verify silicone covers are seated to protect the shock shaft before first run.

For tuners and hobbyists running HPI Baja platforms, this GPM BJ208R/A rear damper is a straightforward replacement or upgrade that focuses on durability and basic adjustability without changing suspension architecture.
