FAQ

Tighter steering control for the Traxxas E-Revo

Fit GPM aluminum knuckle arms to your Traxxas E-Revo to reduce flex and stabilize the front and rear suspension. These CNC style replacements use POM collars to keep bearings seated and cut tolerance play for crisper steering feel and longer service life.

Key upgrades and effects

Material Upgrade: Swapping molded plastic for 6061 T6 aluminum with POM collars increases rigidity and repeatable geometry.
Improved Durability: Delrin lock nuts resist loosening and add long term reliability under heavy use.
Secure Bearing Fit: POM inserts cushion bearings and reduce the chance of displacement from friction or impacts.
Adjustable Installation: Multiple mounting holes let you tune tie rod and knuckle arm angles for steering feel and Ackerman adjustments.

Packing includes

Kncukle Arm - 2pcs
Stainless Steel Round Head Screw 3x20 - 2pcs
Delrin Locknut - 4pcs

Traxxas E-Revo

Can these replace both front and rear knuckles on my E-Revo?

Yes, the set is made for both front and rear knuckle positions on the Traxxas E-Revo, so you can upgrade all four corners for matched handling.

Do I need special bearings or hardware to fit them?

No special bearings are required; the POM collars are sized for standard E-Revo bearings and the kit includes the listed screws and locknuts.

Will these change my steering geometry?

They keep original geometry but the multiple mounting holes let you alter tie rod length and ackerman slightly for a firmer or quicker steering response.
