UMI Performance 2727 Rear Leaf Spring Installation Kit with Grade 8 U-Bolts

The UMI Performance 2727 rear leaf spring installation kit, also sold as leaf spring mounts or leaf spring hardware, replaces the factory T-bolt mounting with Grade 8 U-bolts and fresh polyurethane isolators. It gives the rear leaf spring mounting a stronger, more secure setup for high-horsepower street and strip builds.

Key Features:

• T-bolt to U-bolt upgrade: Four 7/16-20 Grade 8 U-bolts wrap the axle tube for even, secure clamping.
• Polyurethane leaf spring isolators: Locate the rear axle precisely and reduce the deflection of worn factory rubber.
• Alignment bushings: Included with the isolators to keep the axle positioned correctly.
• Zinc-plated steel construction: Resists corrosion.
• Made in the USA: Built by UMI Performance in Philipsburg, PA.
• Stock-location compatible: Designed for use with stock-location rear leaf springs.

This kit helps reduce wheel hop and axle wrap. The result is more consistent launches and straighter tracking.
