This GPM SB021 aluminum front knuckle arm set is an RC-scale steering component made for Team Losi SUPER BAJA models, designed to improve bearing alignment and steering response. The CNC-machined parts provide precise bearing seats and two selectable mounting holes that let you fine-tune knuckle angle relative to the steering turnbuckles.
Functionally the parts stabilize the wheel bearings and CVD connection so the driveshaft rotates with less binding, and they help the steering turnbuckles track more predictably through suspension travel. The kit is intended to replace the plastic knuckles for greater rigidity and repeatable geometry on model tracks or bumpy surfaces.
Hardware supplied with the kit includes stainless steel round head screws 4x28 - 2 pcs, stainless steel button head screws 3x10 - 2 pcs, and stainless steel 4M threaded rods - 2 pcs, together with the knuckle arms. For final assembly use the original top and bottom screws where indicated to retain intended mounting clearances.
Installation notes: fit the knuckle arms so bearings seat squarely, test CVD rotation through the suspension range, and use the alternate hole to adjust steering ackerman and scrub radius. No additional tools are required beyond standard hex drivers for model maintenance.
Use these knuckle arms to secure bearing position and tune steering geometry on Team Losi SUPER BAJA models, keeping the installation and setup procedure consistent with existing turnbuckle and CVD alignments.
