Technical overview for the right front upper suspension arm

This right-side front upper suspension arm is presented as a replacement component for Traxxas Revo front assemblies, intended for users focused on setup consistency and predictable geometry. The arm arrives in blue and is designed to locate at the factory Revo mounting points to maintain baseline suspension geometry on standard builds.

Assembly procedure: verify hinge pin and ball stud fitment, ensure correct right-side orientation and torque fasteners to recommended values. Following installation, validate steering centring, full suspension stroke and absence of rotational or lateral binding at linkage joints.

Performance considerations: the upper arm governs camber change rate and roll centre height; using a like-for-like RE-041A/B preserves the original kinematics, while alternative lengths or offset arms require iterative setup changes and track testing to quantify handling effects.

Post-fit validation of steering, suspension travel and clearances is essential; keep spare arms available for rapid replacement during competitive running.

How does this arm affect camber progression?

Camber progression depends on arm pivot location and length. Using RE-041A/B as a like-for-like swap preserves the original camber curve; altering length or pivot offsets will change the progression and require tuning.

What pre-fit inspections are recommended for race use?

Inspect pin bores, ball-stud seating and link geometry; replace worn pins or balls and verify concentricity to avoid imprecise steering inputs at speed.

Should I remeasure toe and camber after swapping arms?

Yes, re-measure toe and camber after installation and a short break-in run to confirm the setup matches your intended race geometry.

Any special notes for competitive tuning?

Document geometry before changes, make incremental adjustments and test consistently to isolate the handling effect of arm changes on corner entry and mid-corner balance.
