Rear L-shape damper for Baja 208mm

The GPM BJ208R/L is an aluminum alloy rear adjustable L-shape damper engineered for HPI Baja platforms. Supplied as a 1pr set, the kit contains the pair of rear dampers and damper oil rated at 1000 viscosity to support controlled compression and rebound. The L-shape body locates the cylinder and spring to match Baja rear suspension geometry while keeping the overall length compact at 208mm.

This component functions as a direct aftermarket upgrade for improved shock durability and more predictable damping. The adjustable feature permits tuning of damping by changing oil viscosity and spring preload, allowing incremental setup changes to refine traction and chassis balance on loose or uneven off-road surfaces. Use only on compatible HPI Baja models listed in the product title.

Installation guidance: the dampers install into the same rear mounting points as stock L-shape shocks on compatible Baja chassis. Inspect existing mounting hardware and ball-ends for wear prior to fitting, and expel trapped air from the damper during filling to ensure repeatable performance. Begin with the included 1000 viscosity oil as a baseline, then iterate oil weight and spring rates to suit running conditions.

For HPI Baja operators needing a durable, adjustable rear shock solution, the BJ208R/L offers an aluminium upgrade with included 1000 oil to assist setup and iterative tuning.

What mounting points are used for installation?

Install the dampers at the factory rear L-shape shock positions. Confirm alignment and secure ball-joints to maintain correct suspension geometry.

How should I approach oil changes for tuning?

Use the supplied 1000 viscosity oil as a baseline, then evaluate handling changes with incremental viscosity shifts. Record oil weight vs track response to identify preferred setup ranges.

Are there any recommended prefit inspections?

Check ball-ends, mounting pins and seal condition before fitting. Replace any worn hardware to prevent misalignment and premature wear.

What procedure ensures minimal air in the damper?

Fill the damper slowly while cycling the shaft to bleed air pockets. Continue topping up until bubbles cease, then secure seals and verify stroke consistency.

Can these dampers be tuned for different surfaces?

Yes, tune by combining oil viscosity changes and spring preload adjustments; lighter oils and lower preload for faster response, heavier oils and higher preload for greater control on rough terrain.
