This front shock assembly is intended for HPI Baja style cars and is supplied as one pair with an L-shape lower mount and a piggyback reservoir. The units use aluminium bodies and the stated length is 186mm as indicated in the title.
Use and tuning overview: the L-shape lower section positions the lower eye to suit Baja front geometry while the piggyback reservoir holds extra oil to help keep damping consistent under repeated cycles. Tuning changes to pistons, springs or oil weight should be done progressively to refine compression and rebound.
Installation checklist: confirm the mounting hole spacing and total length against your Baja shock towers before installation, fit one side at a time to maintain balanced handling, and verify preload and end-point travel after fitting. The dampers provide adjustment via the reservoir and spring preload where accessible.
For enthusiasts running HPI Baja platforms who want metal-bodied front dampers with piggyback adjustability, the BJ186F/L set is an aftermarket option when the 186mm length and L-mount geometry fit the chassis. Always measure mount points and choose oil and springs to suit your conditions.
