Dobinsons Spring & Suspension's range of 4x4 shackles and pins have been designed and manufactured to maximize the life of both the polyurethane bushes and shackles. Incorporating a recessed twin hole greasable design to ensure both halves of the polyurethane bush receive even grease distribution. Greasing polyurethane bushes not only reduces friction and wear, it also reduces the chances of corrosion on the shackle pins and reduces squeaking.

In some cases Dobinsons also provide anti-inverse shackles to prevent the shackles from inverting on lifted leaf spring vehicles.
