Fixed Pins with Fitting Position Front and Rear, Rear Axle

Fixed pins are the greaseable leaf spring pin and bush kits used to replace worn or seized standard pin hardware at the rear leaf spring eye and shackle mounting positions. On leaf spring rear suspension platforms, the fixed pin at the front spring eye and the pins through the rear shackle are the pivot points about which the spring articulates as it cycles through its travel. Factory pin hardware on 4WD dual cab utes and heavy use platforms is not designed for periodic re-lubrication, and over time seizes within the bush under the combined effect of road contamination, moisture ingress and sustained load cycling. Seized pins accelerate bush wear, make routine bush replacement difficult and introduce binding into the spring pivot that affects ride quality and spring performance under load.

Replacing standard pin hardware with greaseable alternatives at the same time as the bush kits restores correct articulation at every spring pivot position and converts the assembly to one that can be periodically re-lubricated to prevent future seizing. The range covers complete combined greaseable shackle and bush kits that renew all spring eye and shackle positions simultaneously, a targeted front eye bush and greaseable pin kit for platforms where only the front eye requires attention, and a greaseable pin protection cap to shield the installed pin from fuel tank side impact damage on applicable platforms. Most products carry a three-year warranty.

Why Upgrade Suspension?

Standard leaf spring pin hardware that cannot be greased reaches the end of its service life progressively and silently. By the time binding or stiffness is apparent in the spring pivot under articulation, the pin has typically been seized within the bush for some time, with wear accelerating at the bush and pivot interface throughout. Attempting bush replacement on a platform with seized pin hardware adds significant time and difficulty to what would otherwise be a straightforward service.

Upgrading to greaseable pin hardware at the time of bush replacement eliminates the root cause of future seizing and converts every renewed spring pivot position into a maintainable interface. Periodic re-lubrication through the grease point keeps the pin correctly lubricated throughout its service life, extending bush life, maintaining correct spring articulation and ensuring future bush replacement is clean and straightforward rather than complicated by seized hardware.

Fixed Pins Range

The fixed pins range includes:

• Rear Leaf Spring Greaseable Shackle and Bush Kits: Complete vehicle-matched kits supplying polyurethane front eye, rear eye and shackle bush kits together with greaseable fixed pin and shackle hardware, renewing all rear spring pivot positions simultaneously.
• Rear Leaf Spring Front Eye Bush and Greaseable Pin Kits: Kits supplying a polyurethane front spring eye bush and greaseable front eye fixed pin for targeted front eye bush and pin renewal on applicable platforms where rear eye and shackle positions do not require attention.
• Greaseable Pin Protection Caps: Protective caps designed to shield the greaseable front eye pin installation from fuel tank side impact damage on applicable platforms, protecting the pin and grease point from contamination and physical contact.

Why Purchase Fixed Pins?

Renewing leaf spring bush kits without addressing the pin hardware leaves the newly installed bushes operating against pin surfaces that may already be worn, corroded or prone to future seizing. Installing greaseable pin hardware at the same time as the bush kits ensures the renewed bush has a correctly finished, lubricated pivot surface to operate against and introduces a grease point that allows the assembly to be maintained going forward.

For workshops carrying out rear leaf spring services, combined greaseable shackle and bush kits deliver a complete one-purchase solution that addresses every spring pivot position in a single installation, reducing return visits for bush renewal and providing customers with a maintainable rear spring assembly.

Compatible Vehicles

Fixed pins suit a wide range of vehicles, including:

• 4WD dual cab utes with rear leaf spring suspension requiring combined greaseable shackle and bush kit installation to renew all spring eye and shackle pivot positions simultaneously.
• Rear leaf spring platforms where only the front spring eye pin and bush require renewal, using the targeted front eye bush and greaseable pin kit.
• Any platform where a greaseable front eye pin has been installed and a protection cap is required to shield the pin from fuel tank side impact damage.

Installation and Support

Combined greaseable shackle and bush kits are designed for accurate installation at all rear spring eye and shackle pivot positions in a single service. Installation times range from approximately one and a half to three hours depending on the platform. The front eye bush and greaseable pin kit installs in approximately two hours. Installation guides are available across most combined kit 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 for the specific platform and spring configuration.

Repair and Upgrade

Fixed pin hardware is engineered from quality materials to withstand the sustained load cycling, road contamination and moisture exposure that rear leaf spring pivot positions are subject to on 4WD and heavy use platforms. The greaseable design allows periodic re-lubrication to maintain correct pivot articulation and prevent seizing throughout the service life of the installed bush kits. Most products carry a three-year warranty.

Who Fixed Pins Are For

Fixed pins are a practical solution for:

• Professional workshops carrying out rear leaf spring services on 4WD dual cab ute platforms requiring combined greaseable shackle and bush kits that address every spring pivot position in a single purchase and convert the assembly to a maintainable design.
• 4WD owners and experienced DIY users replacing rear spring bush kits who want to upgrade to greaseable pin hardware at the same time to prevent future seizing and establish a maintainable rear spring assembly.
• Anyone requiring a targeted front eye bush and greaseable pin kit where only the front spring eye position requires renewal on an applicable platform.

The right fixed pin kit restores correct spring pivot articulation at every renewed position, eliminates the risk of future pin seizing and delivers a rear spring assembly that performs correctly and remains maintainable throughout its service life.
