The GPM BJ208R/L is an aluminum alloy rear adjustable L-shape damper intended for HPI Baja platforms. Delivered as a 1pr set, the item includes both rear dampers plus damper oil at 1000 viscosity to support tuning of response and rebound. The L-shape form positions the cylinder and spring to match Baja rear suspension geometry while keeping the overall assembly compact at 208mm length.
This aftermarket component offers improved shock consistency and durability over stock units. The adjustability allows you to change the damping feel by selecting different oil viscosities and altering spring preload, which helps refine traction and handling on sandy, loose or rough surfaces. Use this accessory only on the HPI Baja variants shown in the product name.
Fitment guidance: mount the dampers into the same rear locations used by factory L-shape shocks. Verify ball-ends and mounting pins for wear before fitting, and remove trapped air during oil fill to ensure consistent damper action. Start with the included 1000 oil and adjust as track conditions require.
For drivers wanting a dependable, adjustable rear shock for their HPI Baja, the BJ208R/L provides an aluminium upgrade with 1000 oil included to assist first-time setup and gradual tuning.
