RAW 4x4 Heavy-Duty Suspension Lift Kit – Jeep Wrangler JK (2007–2018)

RAW 4x4 Heavy-Duty Suspension Lift Kit – Jeep Wrangler JK (2007–2018)

Transform your trail machine’s load capacity and highway stability with the commercial truck-tough RAW 4x4 Heavy-Duty Suspension Kit for the Jeep Wrangler JK (2007–2018), covering all 2-door and 4-door Sport, Sahara, and Rubicon variants with 3.8L V6, 3.6L Pentastar, and 2.8L CRD engines. Born from a rich pedigree of heavy commercial vehicle engineering by Powerdown, this system replaces fatigued factory coils and shocks to provide up to 50mm of ground clearance — carefully engineered to prevent excessive wear on factory driveshaft boots and maintain correct tracking geometry.

The JK platform is famous for its front and rear quadra-coil solid-axle configuration, and this kit is purpose-built to eliminate the severe highway body sway and rear-end sag caused by permanent overland weights. Whether you’re packing a Quick Pitch Quick-en-Suite Box Unit, interior drawer systems, or heading cross-border on corrugated gravel routes, the upgraded coils and RC-JPJKR-HD Constant-Load Rear Springs stop rear-end sag dead in its tracks. Equipped with massive 41mm-bore Nitro Max shocks in a 60mm outer tube with high-pressure HNBR multi-lip dust and oil seals built to withstand harsh trail grit.

• Front Raised Coil Springs (RC-JPJKF) – 0–50kg / Standard Touring
• Front Heavy-Duty Raised Coil Springs (RC-JPJKF-HD) – 50–100kg / Steel Bar & Winch — mandatory to eliminate nose-dive under heavy steel bumpers

⚠️ Recommended Installation Accessories

The Jeep JK’s solid-front-axle layout means lifting the vehicle modifies the steering tracking angle. We strongly recommend adding the following to your order:

• Heavy-Duty Steering Stabilizer (RAW-SD-5011) – eliminates front-end bump-steer and high-speed wheel wobble on rough dirt tracks
• Adjustable Front Track Bar – re-centres the front axle to restore correct tracking geometry after lift installation

Technical Specifications
