UMI Performance UMI rear frame brace strengthens C10 frames for performance and upgrades. 6426-R

Description:

The UMI Performance Rear Frame Brace (P/N 6426) is the ultimate way to strengthen the back end of your 1973-1987 Chevy or GMC C10, reducing frame flex and providing a solid mounting foundation for fuel tanks and performance upgrades. Designed with laser-cut, tab-and-slot precision construction, this rear crossmember ties the frame rails together with race-proven rigidity—perfect for Pro-Touring and performance street trucks. Whether you’re building a high-horsepower LS swap, installing a Tanks Inc. fuel tank, or just tightening up an aging chassis, the UMI rear frame brace delivers superior strength and fitment. Best of all, this brace is already included in UMI’s 6428 C10 4-Link Suspension Systems, but is also available separately for custom builds or incremental upgrades.
