Lift Junkie 2" Lift Kit to suit Isuzu D-Max 2011+ / Holden Colorado

Using premium brand components, these suspension systems are designed to boost the usability of your vehicle, adding up to 2 inches of extra ride height. They're an excellent upgrade for those who already have a bullbar or are planning to install one later on. The kit helps you avoid ground obstacles more easily, carry heavier loads, improve handling control, and enhance driver sight lines—all without the hassle of complex modifications. You simply swap out your original parts with the included heavy duty shocks and springs, making installation straightforward and maintaining the factory setup.

What you get in the kit:

*Note: C21-386 has full wire upper ends on springs for enhanced strength, while C59-134 features ground flat upper ends for different fitment options.

The RAW 4x4 Nitro range offers heavy duty, gas-charged shock absorbers that significantly improve ride quality. They help reduce body roll and increase vehicle stability, especially when lifting your 4WD. With a larger body that allows more oil capacity and nitrogen gas for better cooling, these shocks are built to last, outperforming many well-known rivals at a competitive price point. They’re perfect for recreational 4WDer looking to lift their vehicle while maintaining excellent suspension performance.

Features include a bigger bore size to lower internal pressure, high-performance oil for consistent damping across conditions, and durable HNBR seals with wiper lips to keep dust and grime out. The large body provides extra oil capacity, resisting fade during extended use, and highly charged nitrogen gas helps prevent shock fade over time, ensuring reliable handling on and off-road.

RAW 4×4 leaf springs are engineered for a smooth, stable ride while increasing your vehicle’s ride height and load-carrying capacity. They’re built from high-quality steel, with Military Wrapped Eyes offering added safety in case a main leaf breaks. The tapered and diamond-cut design helps distribute loads evenly, giving you a reliable and comfortable suspension system. Inter-leaf anti-friction liners reduce noise and friction—excluding some part numbers—improving overall ride comfort and spring longevity. The high-strength clips with nylon insulators keep everything aligned, reducing wear and noise, and Nyloc nuts secure these clips to prevent loosening during tough off-road adventures. The two-stage leaf pack provides additional support for heavily laden vehicles, enhancing both load capacity and suspension travel to keep you confident on challenging terrains.
