Leaf Springs with Fitting Position Front Axle, Rear Axle

The leaf springs category brings together the hardware and service kits needed to maintain, rebuild and upgrade rear leaf spring assemblies on 4WD dual cab utes and ute platforms. It covers the three key components of a complete leaf spring service: greaseable shackle and bush kits that renew the spring eye and shackle bushes while upgrading the pin hardware to a maintainable greaseable design, universal U bolts in a range of sizes and top configurations for securing the spring pack to the axle housing, and greaseable front eye pin kits and protection caps for targeted spring front eye serviceability.

Together, these components allow the full rear leaf spring mounting and clamping system to be serviced or upgraded in a single purchase, ensuring the spring assembly is correctly located, correctly secured and maintainable for the long term. A practical and comprehensive solution for workshops and experienced DIY users carrying out rear leaf spring servicing on 4WD dual cab ute platforms. Most products carry a three-year warranty.

Why Upgrade Suspension?

Rear leaf spring hardware is among the most frequently neglected components on working 4WDs and dual cab utes, yet it directly affects rear axle location, spring compliance, load stability and the long-term maintainability of the rear suspension system. Worn or corroded U bolts that have been over-torqued or service-stretched lose clamping tension, allowing the spring pack to shift on the axle perch and affecting rear axle location and suspension geometry. Standard shackle and eye pin hardware that cannot be greased seizes over time, making future bush replacement difficult and allowing wear to accelerate unchecked.

Renewing U bolts with quality replacements and upgrading to greaseable pin and shackle hardware at the same time restores correct spring clamping and mounting compliance, ensures the shackle assembly can be maintained going forward and delivers a rear suspension system that performs correctly and remains serviceable across years of towing, loading and off-road use.

Leaf Spring Range

The leaf spring range includes:

• Universal U Bolts: Dimensionally specified square top and round top U bolts in a range of internal diameters, lengths and thread specifications for securing the rear leaf spring pack to the axle housing across a wide range of applications.
• Greaseable Shackle and Bush Kits: Complete rear leaf spring service kits supplying polyurethane front eye, rear eye and shackle bush kits together with greaseable fixed pin and shackle hardware for applicable 4WD dual cab ute platforms.
• Greaseable Front Eye Bush and Pin Kits: Kits supplying a polyurethane front eye bush and greaseable front eye pin for targeted front spring eye serviceability on applicable platforms.
• Greaseable Pin Protection Caps: Protective caps for greaseable front eye pin installations on applicable platforms, protecting the pin and grease point from contamination and extending service life.

Why Purchase Leaf Spring Parts?

Servicing the rear leaf spring assembly with quality replacement hardware ensures the spring pack is correctly clamped, correctly located and correctly supported at each mounting interface. U bolts that are no longer within their designed clamping range should be replaced rather than re-torqued, and spring eye and shackle pin hardware that cannot be greased should be upgraded to a serviceable design at the same time to avoid premature wear and the difficulty of future bush replacement.

Purchasing greaseable shackle kits, U bolts and associated hardware as part of a complete rear spring service ensures every element of the leaf spring mounting and location system is addressed in a single session, delivering a rear spring assembly that is correctly assembled and maintainable from the moment the service is completed.

Compatible Vehicles

Leaf spring parts suit a wide range of vehicles, including:

• 4WD dual cab utes with rear leaf spring suspension requiring U bolt replacement, greaseable shackle and bush kit installation or greaseable front eye pin kit fitment as part of a rear spring service.
• Any rear leaf spring equipped vehicle where U bolts require replacement due to wear, corrosion or service stretch, using the appropriate dimensionally specified universal U bolt from the range.
• Any rear leaf spring platform where shackle and eye pin hardware is being upgraded to a greaseable design for improved long-term maintainability.

Installation and Support

Leaf spring hardware is designed for accurate installation at the spring eye, shackle and axle clamping positions of the rear leaf spring assembly. U bolt installation time is approximately one hour. Greaseable shackle and bush kit installation times range from approximately one and a half to three hours depending on the platform. Installation guides are available across most greaseable shackle and bush kit products. For additional technical assistance, a dedicated support team is available to help ensure correct product selection for the specific platform and spring assembly configuration.

Repair and Upgrade

Leaf spring U bolts and hardware are manufactured to withstand the clamping loads, vibration and environmental exposure that rear spring mounting components are subject to in everyday and demanding use. Greaseable pin and shackle hardware is engineered for long-term serviceability, allowing periodic lubrication to maintain smooth pivot articulation and prevent seizing under sustained off-road and heavy load use. Most products carry a three-year warranty.

Who Leaf Spring Parts Are For

Leaf spring parts are a practical solution for:

• Professional workshops carrying out complete rear spring servicing on 4WD dual cab ute platforms requiring U bolt replacement, greaseable shackle and bush kit installation and associated hardware as part of a thorough rear suspension service.
• 4WD owners and experienced DIY users replacing rear spring U bolts and upgrading shackle hardware to a greaseable design to improve rear spring clamping integrity and long-term maintainability.
• Anyone replacing or servicing rear leaf spring assemblies who needs dimensionally specified U bolts in the correct size for their specific axle and spring pack configuration.

The right leaf spring hardware ensures correct spring clamping, correct axle location and a rear spring assembly that remains correctly assembled and maintainable through every load cycle and off-road session.
