Holden Colorado (2012-2025) PSR / DMAX Extended Shackle 1' Lift
PSR's extended shackle for the Holden RG Colorado & Isuzu D-MAX models is a super heavy duty leaf spring shackle. Designed to a length that provides 1' of lift it features side plates made from 10mm laser cut steel, CNC machined and welded pins. Pins are greaseable for a long service life. This shackle was designed due to its ability to give 1' lift and free up leaf spring movement. The factory shackle is only 85mm on and severely restricts leaf movement. Couple this shackle to a 2' lift leaf to gain a 3' lift to complement a front end that only allows for a 3-3.5' lift. Coated Black to blend with the chassis.
- Suits:
- Holden RG Colorado
- Isuzu D-MAX

Pre-Order Information
Items where the “Add to Cart” button is replaced with “Pre-Order” are classified as pre-order items. When placing a pre-order, a warning box will appear outlining the terms and conditions, including the estimated delivery timeframe.
Please keep the following in mind:
Stock is not on hand – we have no control over delivery times until the stock arrives.
Patience is required – pre-ordering secures your item, but fulfilment depends on supplier availability.
High-demand items – pre-orders are the best way to lock in popular products, which often sell out before they even land.
Allow a buffer – please add 2–3 weeks to the provided ETA to account for any unforeseen delays beyond our control.
Pre-ordering ensures you don’t miss out on in-demand products, and we’ll keep you updated as soon as your order is ready to ship.
