Rear Greasable Shackles

The Dobinsons SK21-059 is a pair of rear greasable shackles engineered to enhance the performance and longevity of your vehicle's leaf spring suspension system. By facilitating regular lubrication, these shackles effectively reduce friction and wear on polyurethane bushes, leading to improved ride comfort and an extended component lifespan. They are an ideal upgrade for drivers seeking to boost their vehicle's suspension reliability and ride quality through enhanced maintenance capabilities. Constructed for durability and resilience under demanding conditions, these shackles are built to withstand both on-road and off-road driving. Key features include a recessed twin-hole greasable design that ensures even grease distribution to both halves of the polyurethane bush, promoting consistent lubrication and minimizing friction. External grease nipples allow for straightforward maintenance, enabling easy servicing and prolonging the life of your suspension components. The robust zinc coating provides excellent corrosion resistance, ensuring longevity and reliable performance over time. Certain models of the SK21-059 also incorporate an anti-inverse feature. This design prevents the shackles from inverting on lifted leaf spring vehicles, which helps maintain proper suspension geometry. This specific feature is crucial for lifted applications to ensure consistent and safe suspension operation. These greasable shackles are specifically designed to fit 4x4 models of the GM Colorado, GM D-Max, and Holden Colorado. Fitment includes models from 2012 to mid-2020 for the Isuzu D-Max TFS85 and similar ranges for the Chevrolet Colorado and Holden Colorado. It is recommended to confirm fitment with a specialist before ordering to avoid potential issues, as some retailers state the part does not fit vehicles that are not 4x4 models.
