Chain / Belt Axle Adjuster Plates

Heavy-Duty Axle Adjuster / Chain Tensioner Plates for Pre-2005 Dyna, FXR & Early Sportster Models

Upgrade your rear axle stability with our Heavy-Duty Chain Tensioner Plates, designed to replace the weak factory end caps on the swingarms of select Harley-Davidson models. These precision-cut plates are made specifically for 2005 and earlier Dyna, FXR, and 2003 and earlier Sportster models, where the factory axle adjuster plates are prone to distortion under hard riding, aggressive launches, or stunting.

Our plates are approximately 3x thicker than OEM, ensuring your axle stays perfectly aligned and your chain tension is held securely—even under high-stress conditions.

 Key Features:

Upgraded Swingarm End Caps – Replaces factory chain tensioner plates to prevent distortion

Cold Rolled Mild Steel – Built tough to handle aggressive riding and heavy loads

Thicker Than OEM – Triple the thickness of stock plates to maintain axle alignment

Durable Black Powdercoat Finish – Corrosion-resistant and built to last

Sold as a Pair – Includes both left and right side plates

Made in the USA

 Compatibility:

Dyna Models (2005 & earlier)

FXR Models (All years)

Sportster Models (2003 & earlier)

Perfect for performance riders, stunt setups, or anyone wanting a more reliable rear axle hold than the stock swingarm plates provide.
