This purple-finished aluminium throttle bellcrank linkage is an aftermarket replacement aimed at HPI Savage Nitro Off Road Series vehicles. It replaces the original bellcrank that couples the throttle servo to the carburettor linkage and is intended to offer a stiffer mounting point for throttle control.
Use the linkage when replacing worn parts or when experimenting with throttle geometry to influence response and servo behavior. The alloy construction balances stiffness and weight for typical off-road duty.
Install this linkage to renew throttle linkage hardware or adjust servo geometry on Savage nitro trucks; verify your truck's layout before purchase.
