Daystar Leaf Spring and Shackle Bushing Kit

Daystar Leaf Spring & Shackle Bushing Kits: Polyurethane Built to Last

When the rubber bushings connecting your leaf springs, shackles, and frame start to wear out, the consequences go beyond a rough ride. Loose shackles can cause leaf springs to shift and throw off the alignment of the axle and wheels — a serious concern whether you're rock crawling in a Jeep, hauling heavy loads in a pickup, or daily-driving an SUV on rough roads. Daystar has been engineering a solution to this problem since 1977, and their Leaf Spring and Shackle Bushing Kits are one of the brand's most trusted product lines.

Why Polyurethane Outperforms Rubber

Daystar has been designing and producing precision plastic components for four-wheel-drive trucks, motocross bikes, passenger cars, and mountain bikes since 1977. That decades-long specialization in polymer engineering is on full display in these bushing kits. Daystar's leaf spring and shackle bushings are made of high-quality polyurethane — resistant to wear and UV rays, making polyurethane a much better-suited material than rubber.

Besides being more resistant to wear, poly bushings brush off the environmental factors that can degrade rubber, like road salts, motor chemicals, and road grime. Daystar has developed several families of proprietary polymer formulations that give them the ability to match material properties to specific applications. The result is a bushing that still provides some give but holds its shape much longer than the original rubber and keeps your leaf springs where they need to be.

Specific Kits for Jeeps, Trucks & More

Daystar's Leaf Spring and Shackle Bushing Kits are vehicle-specific, precision-engineered to drop in without modifications. For example, kits like the KJ02002BK and KJ02003BK are designed to fit 1976–1986 Jeep CJ5 and CJ7 models front and rear, while the KC02008BK targets a 1.25 in. ID spring eye application for Dodge trucks. These kits have been specifically engineered to outstrip the vibration-dampening benchmark of the vehicle's OEM bushings, providing increased support at the pivot points where the leaf springs attach to the shackle and where the shackle attaches to the vehicle's frame.

Upgrading to Daystar's polyurethane leaf spring and shackle bushings can also help improve your vehicle's load-carrying capacity and towing ability. Firmer bushings mean firmer springs, less body roll, and better handling from your vehicle.
