HPI Bullet 3.0 Compatible Front Knuckle Arms Black Alloy - BUL-18000-BK by Jazrider  [BUL-18000-BK]

Bullet 3.0 alloy knuckle arms overview

These black alloy front knuckle arms are presented as an aftermarket accessory for HPI Bullet pilots aiming to refine front-end performance. They are designed to work with Bullet 3.0 MT and ST variants as an alloy substitute to standard knuckles.

The part serves as both a replacement for worn front suspension components and as a tuning upgrade where increased rigidity can influence steering precision and part longevity. The black finish remains cosmetic and does not affect mechanical fit; verify your Bullet 3.0 MT or ST front mount arrangement before fitting.

Installation is suitable for those comfortable with front-end work: remove the existing knuckles, check mounting and linkage clearance, then secure the alloy arms using the original or supplied fasteners. Validate wheel alignment and steering travel after installation.
