The Old Man Emu BP-51 coilover kit is an integrated suspension system tuned for Toyota Tacoma applications to improve ride control, comfort and load-carrying capacity. It uses BP-51 internal bypass shocks with 10 levels of independent compression and rebound adjustment for on-vehicle tuning. Remote reservoirs and a hard‑anodized 6061 aluminum shock body aid cooling during extended off-road use, and the kit includes an upper control arm and lift calibrated to vehicle weight ranges.
