FX28-015 FX28 Steel Front Axles

Reverse Titanium Axles V2 – Adjustable Trackwidth System

Upgrade your front end with our V2 Reverse Axles, now machined from titanium for improved durability and long-lasting performance. These axles allow you to fine-tune your front offset by 1mm, adjustable in 0.5mm increments using the included M3 x 0.5mm axle shims.

Compatibility

• Reflex Racing RX28

• GL Racing chassis

• Atomic chassis

Why Reverse Thread?

By reversing the thread direction and using a screw instead of a nut, the axle system greatly reduces the chance of your front wheels snagging on RCP rails, especially when running low-offset wheels.

What’s Included

• 2× Titanium Reverse Axles (V2)

• 4× M3 x 0.5mm Copper Shims

• 2× M2 × 4mm Button Head Screws

Pro Tip

Depending on the wheels used, there may be a small amount of axial side-to-side play.
To eliminate this, you can lightly sand the outer axle surface to reduce the width slightly.
