UMI Performance 70-81 Leaf Spring Delrin Shackle Kit

Starting with the Delrin bushings, this shackle kit from UMI Performance is built to reduce unwanted movement in your rear axle. Delrin is a tough, low-friction material that significantly cuts down on side-to-side and fore-aft play, which is crucial for better handling, especially when you're pushing your car on the street or at higher performance levels. These bushings are manufactured in-house by UMI, ensuring a well-made component for your suspension.

The kit includes laser-cut, heavy-duty shackles that are finished with a durable gloss black powder coat, and all the necessary Grade 8 hardware to get the job done. This shackle kit is designed to work with UMI's own P/N 2620 rear leaf springs, but it's also compatible with other leaf springs that mount in the stock location. By minimizing suspension flex, you'll notice a more consistent and responsive feel from your rear suspension.
