Traxxas Aluminum Pivot Ball Cap Set With Tool Hard-Anodized Set Of 8 (TRX7033X)

Tighten up the suspension of your 1/16 Scale Traxxas model with this premium Aluminum Pivot Ball Cap Set. If your mini E-Revo or Slash feels sloppy in the corners or the wheels wobble even when tight, the stock plastic caps are likely worn out.

This set replaces the factory plastic retainer caps that hold the pivot balls into the axle carriers (hubs). Machined from aluminum and Hard-Anodized with PTFE-Coating, these caps provide a silky smooth surface for the suspension to articulate while holding the pivot ball much more securely than plastic ever could.

Key Features

• Hard-Anodized & PTFE Coated: The dark grey finish isn't just for looks; it is a friction-reducing coating (Teflon-impregnated) that allows your suspension to move freely without binding, even when tightened down.

• Precision Threading: Aluminum threads hold their position significantly better than plastic, preventing the caps from backing out during a run (a common issue with the stock 1/16 trucks).

• Complete Set: Includes all 8 Caps needed to do the entire truck (4 for the front knuckles, 4 for the rear knuckles).

• Tool Included: Comes with a specific 5mm Hex Wrench designed to fit the internal hex of these caps perfectly for easy adjustment.

Installation Advice

Don't Over-Tighten! The goal of these caps is to remove "slop" (wiggle), not to clamp the suspension shut.

1. Remove Old Caps: Unscrew the plastic caps from your axle carriers.

2. Clean: Wipe off the pivot balls to ensure no grit is trapped inside.

3. Install New Caps: Thread the aluminum cap in until it touches the ball.

4. The "Fall" Test: Lift the suspension arm up and let go. It should fall under its own weight. If it stays stuck in the air, the cap is too tight. Back it off 1/8th of a turn until the arm moves freely but has no wiggle.

5. Threadlock: Because these are metal-on-plastic (aluminum cap into plastic hub), DO NOT use threadlock (Loctite). It can attack the plastic hub. The precision threads should hold fine on their own.
