HPI Baja 186mm Alloy Front Adjustable Spring Damper by GPM BJ186F/A  [BJ186F/A]

Front adjustable spring damper for HPI Baja

This is an RC-scale front adjustable spring damper intended for use on HPI Baja 1/5 chassis applications, supplied as a 1 pair set by GPM BJ186F/A. The component is presented as a drop-in style shock assembly for front suspension replacement or upgrade on compatible Baja models.

The damper measures 186mm overall length and is described with alloy construction and alloy ball ends, and it includes a silicone cover for the shock shaft to reduce debris ingress. The adjustable feature supports incremental setup changes to spring preload and the initial response of the front suspension.

Installation follows standard shock replacement procedures for Baja front mounts, aligning the ball ends with the factory mounting points and verifying travel and articulation after fitment. Use measured adjustments and test runs to fine-tune preload to match your track or terrain preference, noting this is an RC accessory and intended only for scale model suspension tuning.

For replacement front shocks or a metal-bodied option with protective silicone covers, this GPM BJ186F/A 186mm pair provides a straightforward path to adjust front suspension characteristics on HPI Baja models.
