GPM Racing Aluminium Front Upper Suspension Arm for Losi 1/6 Super Baja Rey 4x4 (SB054)

Precision machined front upper arms

Engineered for Team Losi SUPER BAJA applications, this front upper arm pair provides a rigid mounting point for the knuckle and reduces pivot play. Supplied as one pair (2 pcs), the arms are CNC-machined from 6061 T6 aluminium to replace compliant plastic or stamped metal arms where improved stiffness and repeatable geometry are required for competitive setups.

Pressed Delrin collars in the pivot bore reduce radial clearance and ensure repeatable pivot alignment. Stainless steel ball elements, rings and screws are specified to resist corrosion and maintain durable bearing surfaces under repeated loading. The arm profile preserves original suspension kinematics while increasing torsional stiffness to limit deflection under lateral loads.

Installation mirrors standard suspension arm replacement procedures: remove factory arms, transfer any required bushings or hardware, and install the replacement arms using the stock hinge pin and knuckle locations. The CNC tolerances and anodised finish support consistent part interchangeability when correctly mounted.

Specifications

• Item Front upper suspension arms, 1 pair (2 pcs)
• Material 6061 T6 aluminium with Delrin collars and stainless steel hardware
• Model Number SB054
• Compatibility Team Losi SUPER BAJA

For hobbyists seeking a precision, stiffer front end and consistent steering behaviour on Super Baja chassis, these CNC 6061 T6 arms provide robust serviceable upgrade performance and dimensional reliability.

This item is compatible with

• TEAM LOSI Super BAJA REY 4X4

Compatibility and fitment details

The arms are machined to mate with stock hinge pin and knuckle locations on Team Losi SUPER BAJA platforms, enabling direct fitment in standard configurations.

Serviceability of pivot components

Delrin collars are replaceable and should be inspected for wear; stainless hardware can be maintained or renewed to preserve joint integrity.

Effects on suspension tuning

Increased arm stiffness reduces unwanted compliance, improving steering precision and making suspension tuning more predictable under load. Write Product Review Please sign in your account before you can write any review. Sign In Close
