Stop Rear Mount Failures on Your Thunderheader Exhaust
For years in our welding shop, we’ve repaired blown-out rear mount tabs on Thunderheader exhaust systems. The factory setup uses a small bolt head in the slotted flange, which can cause the slot to spread and crack over time.

Our Thunderheader Rear Mount Repair Plates are engineered to eliminate this common problem. Featuring a threaded 5/16"-18 hole that fits snugly into the rear mount slot, these plates distribute the load across the full bracket length. This design dramatically reduces the risk of cracking or loosening while maintaining the same adjustability as a standard nut.

Key Features:

Durable Cold-Rolled Mild Steel – Built for long-lasting strength.

Threaded 5/16"-18 Hole – Snug fit for secure mounting.

Load-Spreading Design – Prevents slot damage and cracking.

Direct Fit for Thunderheader Exhausts – Easy install, no welding required.

Compatible Models – Harley-Davidson Dyna, Sportster, FXR, and Softail.

Kit Includes:

(2) Steel repair plates

Whether you’re repairing damage or preventing future failures, these plates are the perfect upgrade for your Thunderheader-equipped Harley.
