208mm rear shock engineered for Baja platforms

The BJ208R/A is a rear spring damper specified for HPI Baja configuration, built around a 208mm aluminium shock body with silicone dust boots and alloy ball ends. It is intended as a durable, serviceable replacement that supports routine maintenance and tuning workflows.

Technical role and tuning: this damper permits spring preload adjustment and multiple mounting positions to influence damping rates, rebound control and rear traction on jumps and rough terrain. It is compatible with standard RC springs and allows shock oil changes to tune dynamic response.

Assembly and service notes: the damper fits a 208mm mounting length and installs using existing rear shock mounts. Installers should verify correct ball end thread engagement, seat silicone boots fully to protect the shaft and use the vehicle original fasteners. Periodic inspection of seals and ball ends will extend service life.

Designed for hobbyists and tuners who want a robust, CNC-friendly upgrade path, the BJ208R/A supports standard spring and oil tuning while simplifying routine maintenance.

What internal dimensions are important for spring fitment?

Confirm free length and inner diameter of springs against the damper perch and guide; correct spring seating prevents binding and ensures predictable preload adjustment.

Which shock oil viscosity range is recommended for tuning?

Use a range of oils from light to medium for fine tuning; lighter oil for quicker response, heavier oil for increased damping. Match viscosity to vehicle weight and driving conditions.

How should I check alloy ball end wear?

Inspect the ball surface and bore for rounding or play. Replace worn ball ends to prevent binding and maintain correct suspension geometry.
