HPI Baja Front L-mount Alloy Dampers BJ186F/L by GPM  [BJ186F/L]

L-mount Front Alloy Dampers

This is a front shock assembly intended for HPI Baja style machines, supplied as one pair with an L-shaped lower mount and an integrated piggyback reservoir. The construction uses aluminium bodies and the overall length is 186mm as noted in the title.

Setup and function: the L-mount positions the lower eye to suit Baja front geometry while the piggyback reservoir separates oil volume to help maintain consistent damping during heavy or repeated impacts. Work through tuning in steps when swapping pistons or springs to refine compression and rebound.

Installation advice: measure your mounting hole spacing and confirm the 186mm length prior to fitting, change one side at a time for predictable handling differences, and verify preload and travel limits after installation. The dampers offer adjustment via the reservoir and spring preload.

For those running HPI Baja platforms who prefer metal-bodied front dampers with piggyback adjustability, the BJ186F/L set is a suitable aftermarket option when geometry and length match. Always double-check mount dimensions and pick oil and springs to match your surface.
