Bulk Leaf Spring Bushes

Whiteline bulk leaf spring bushes give workshops, suspension specialists and fleet operators a ready supply of polyurethane spring eye and shackle bushes in common sizes. Supplied as loose bushes in large trade packs, they let you service leaf-sprung 4WDs, utes, pick-ups and commercial vehicles quickly, without ordering individual kits for every job.

Leaf spring bushes are a critical service item for any leaf-sprung vehicle. Keeping the most-used sizes on the shelf means every job can be completed on the day, at a lower cost per bush.

What Leaf Spring Bushings Do

A leaf spring attaches to the chassis at both ends: through a fixed hanger at the front and a swinging shackle at the rear. Bushes inside the spring eyes and shackles form the pivot points that let the spring flex and change length as the suspension moves.

These bushings locate the axle, allow smooth articulation, and absorb vibration before it reaches the chassis. When they wear, the axle can shift under braking and acceleration, the springs can move sideways, and the vehicle becomes noisy, unstable and harder to control, especially when towing or loaded.

Why Workshops Buy Leaf Spring Bushes in Bulk

Leaf spring bushes are replaced regularly on vehicles that tow, carry loads and travel on rough roads. For workshops servicing these vehicles every day, bulk packs offer clear advantages:

• Lower cost per bush than individual kits
• Same-day servicing, without waiting on parts
• Fewer reorders, reducing admin and freight
• Consistent quality from one trusted source
• Less packaging waste than individually boxed kits

What?s in a Bulk Leaf Spring Bush Pack

Each bulk pack contains a large quantity of loose leaf spring bushes in a single size, suited to specific vehicles and fitting positions. Bushes are supplied without pins, bolts or sleeves, so workshops can pair them with the hardware they already stock, or reuse serviceable hardware where appropriate.

Each listing shows the bush dimensions, fitting position, pack quantity and applicable vehicles.

Spring Eye and Shackle Bushes

• Front eye bushes sit in the front eye of the spring, where it mounts to the fixed hanger. They carry high loads and control axle location.
• Rear eye bushes sit in the rear eye of the spring, where it connects to the shackle.
• Shackle bushes sit in the upper shackle mount on the chassis, allowing the shackle to swing as the spring lengthens.

Stocking the sizes for each position you service most means a complete spring bush refresh can be done in one visit.

Rubber vs Polyurethane Leaf Spring Bushings

Factory rubber bushes are soft and quiet when new, but they compress, crack and tear under load, heat, water, dirt and oil. On vehicles that tow, tour or work hard, rubber bushes often wear out long before the springs do.

Whiteline polyurethane bushes offer outstanding abrasion resistance, high load-bearing capability, flexibility and increased tensile strength. They resist oil, grease, ozone and weathering, so they hold their shape and keep the axle located far longer. For workshop customers, that means fewer comebacks and longer intervals between bush replacements.

When Leaf Spring Bushes Need Replacing

Common signs a vehicle needs new leaf spring bushes:

• Clunking or knocking from the rear over bumps, or when braking and accelerating
• Squeaking or creaking from the spring eyes and shackles
• Rear-end sway or instability when towing or loaded
• The vehicle tracking off-centre, or pulling under braking
• Uneven rear tyre wear

To confirm, inspect with the vehicle safely supported:

• Look for cracked, split, squashed, missing or displaced bushes at each eye and shackle.
• Lever between the spring eye and hanger, and between the shackle and chassis, to check for movement.
• Check spring pins and shackle bolts for wear, steps or corrosion.

Fitting Leaf Spring Bushes in the Workshop

• Support the vehicle securely on the chassis, and take the load off the springs before removing the pins and bolts.
• Remove the old bushes and any outer sleeves completely, and clean the spring eyes and shackles.
• Lubricate the polyurethane bushes with a grease suitable for polyurethane, then press them into place.
• Replace any worn, stepped or corroded spring pins and shackle bolts.
• Tighten fasteners to specification with the vehicle at normal ride height. This prevents the bushes being preloaded.

Maintenance and Bush Life

• Inspect spring eyes and shackles at every service, and before long tows or trips.
• On setups with greasable pins, grease at the recommended intervals, especially after water crossings and dusty conditions.
• Check spring and shackle bolt tightness regularly.
• Replace worn pins and bolts promptly, as they accelerate bush wear.

Heavy loads, frequent towing, deep water and corrugated roads all shorten bush life, so recommend more frequent inspections for vehicles used in these conditions.

Vehicles and Applications

Bulk leaf spring bushes suit leaf-sprung 4WDs and 4x4s, utes and pick-ups, vans, light commercial vehicles and fleet vehicles. They also suit older passenger cars and classics with leaf spring rear suspension, using common bush sizes.

Who Bulk Leaf Spring Bushes Suit

Bulk leaf spring bushes suit 4WD and 4x4 workshops servicing touring and work vehicles, and suspension specialists carrying out leaf spring refreshes and upgrades. Fleet maintenance operators servicing utes, vans and light commercials use them too, as do mechanical workshops that regularly replace spring eye and shackle bushes, and resellers supplying leaf spring bushes to workshop customers.
