Leaf Spring Bushes for UNIVERSAL PRODUCTS BULK/TRADE PACKS ALIGNMENT SHIMS

ALIGNMENT SHIMS BULK/TRADE PACKS Leaf spring bushes are the polyurethane bush kits used to replace worn rubber bushes at the front eye, rear eye and shackle positions of leaf spring suspension assemblies. The front eye bush connects the front of the spring to the chassis bracket, the rear eye bush connects the rear of the spring to the shackle, and the shackle bush connects the shackle to the chassis. Together, these three positions control the compliance, location and articulation of the entire spring assembly. Worn leaf spring bushes introduce play, spring movement beyond the designed operating envelope and increased NVH, affecting ride quality, load stability and rear axle location consistency.

Quality polyurethane leaf spring bush kits restore correct compliance and spring eye location at each position, reducing unwanted movement, improving load stability and lowering NVH. The ALIGNMENT SHIMS BULK/TRADE PACKS range covers individual position kits for targeted single-position replacement as well as complete kits covering all positions in a single purchase, saddle insulator and slipper pad kits for vehicle applications, greaseable shackle and pin kits for 4WD and ute platforms, and trade bulk packs for workshop volume requirements. Installation guides are available across most products. Most products are backed by a lifetime warranty.

Why Upgrade ALIGNMENT SHIMS BULK/TRADE PACKS Suspension?

Leaf spring bushes are among the most heavily loaded bush positions on any vehicle with rear leaf spring suspension. They carry the full weight of the vehicle in rebound, the full load under acceleration and braking, and the lateral forces generated during cornering, all while allowing the controlled articulation that the spring assembly requires to function. Factory rubber bushes in these positions deteriorate progressively, softening and cracking under continuous load cycling and road contamination.

As leaf spring bushes wear, the spring assembly gains play at the eye and shackle mounting positions, allowing the ALIGNMENT SHIMS BULK/TRADE PACKS rear axle to move beyond its correct operating position and contributing to rear end wander, increased NVH and reduced load stability under towing and carrying conditions. Replacing worn leaf spring bushes with quality polyurethane alternatives restores correct spring eye compliance and location, eliminates play at the mounting interfaces and delivers a more stable, controlled and refined rear suspension character that maintains its performance for longer than factory rubber equivalents.

Why Purchase ALIGNMENT SHIMS BULK/TRADE PACKS Leaf Spring Bushes?

Allowing worn leaf spring bushes to remain in service results in progressive rear axle compliance drift, increased NVH, rear end instability under load and accelerated wear at the spring eye and shackle mounting interfaces. Replacing them with quality polyurethane bush kits restores correct spring eye compliance and location at each position, eliminating play and delivering a more stable, controlled and refined rear suspension performance from the moment of installation.

For workshops servicing 4WDs, dual cab utes and classic vehicles, ALIGNMENT SHIMS BULK/TRADE PACKS leaf spring bush renewal is a routine and high-impact service that addresses one of the most common sources of rear end NVH, handling imprecision and load instability on these platforms. With individual position kits for targeted repairs, complete kits for full spring assembly renewal and trade bulk packs for volume requirements, the range provides the right solution for every service scenario.

Installation and Support

ALIGNMENT SHIMS BULK/TRADE PACKS Leaf spring bush kits are designed for accurate installation at the front eye, rear eye and shackle mounting positions of the leaf spring assembly. Installation times range from approximately one to three hours depending on the application and number of positions being renewed. Installation guides are available across most products to support both professional workshops and experienced DIY users. For additional technical assistance, a dedicated support team is available to help ensure correct product selection and fitment for the specific platform.

Repair and Upgrade

ALIGNMENT SHIMS BULK/TRADE PACKS Leaf spring bushes are manufactured from high-strength polyurethane engineered to withstand the compressive load, articulation cycling and environmental exposure that leaf spring mounting positions are subject to in everyday and demanding use. Resistant to oil, heat and road contaminants, polyurethane leaf spring bushes maintain their compliance characteristics for longer than factory rubber alternatives, delivering more consistent spring eye location and rear suspension performance throughout their service life. Most products are backed by a lifetime warranty.
