The GPM BMT056 is a CNC-style alloy rear suspension arm made to fit HPI Bullet 3.0 MT and ST models. This direct-fit replacement keeps the stock suspension geometry while replacing weaker plastic arms with a stiffer alloy option for hobby nitro short-course use.
This description covers fitment notes, simple installation checks, and how the arm affects chassis tuning. The arm helps deliver more consistent behaviour under load, reduces unwanted flex in corners, and stands up to frequent track sessions better than factory plastic pieces.
Follow basic RC workshop practice when fitting alloy arms: check ball studs and mounting hardware, ensure pivot pins seat correctly, and recheck toe and camber after installation to retain predictable handling.
