HPI Bullet Front Suspension Arms for Tuning Black Alloy - BUL-18003-BK by Jazrider  [BUL-18003-BK]

Tuning-focused front arm upgrade

This product is an RC-scale front suspension arm set intended for HPI Bullet models and carries the model identifier BUL-18003-BK. The black alloy arms are manufactured as a direct replacement for the front suspension layout used on Bullet 3.0 MT and ST (Nitro Engines).

For tuning applications the alloy arms provide a firmer pivot for the front suspension, which helps retain consistent steering geometry through aggressive driving and when modifying damping or spring rates. The upgrade is aimed at nitro short-course and stadium truck builds that need more robust linkage components than typical plastic arms.

Fitting notes: confirm hinge pin and ball stud fit, inspect related fasteners for wear, and verify wheel alignment after installation. Check clearances with shock towers and steering linkages when using alloy arms, and avoid overtightening hardware to prevent thread damage during setup.
