Modern Design Philosophy
While other kits on the market replicate OEM suspension geometry designs (some over 30 years old), JRace has started from scratch with modernc omponents, to give you the best driving experience possible with today's technologies.
Years of Development
After years in the design stages, hundreds of hours in CAD, and ongoing revisions, JRace has achieved what others in the industry say is not possible or viable on the 70 series chassis. The JRace Detour 70 is the most technically advanced coil conversion on the Australian market.
Enhanced Stopping Power
Enhanced stopping power for safer, more controlled descents incorporating upgraded handbrake, brake booster and lines.
Double Triangulation
Our IP-registered double triangulation enhances stability and roll control, delivering safe, confident handling under load, cornering, towing, or accelerating.
Custom-Tuned Performance
Custom suited coil springs paired with optimised shock lengths and custom valving for maximumon-road comfort while maintaining articulation off-road.
Heavy-Duty Build
Rear axle capacity up to 3T, engineered for over 4T GVM. Weld-in approach for a complete factory-like installation with maximum strength.
Versatile Load Management
Medium duty coil springs paired with Airbag assist system allow versatility for varying loads and towing.
SSM approval
SSM Federal Approval (pre-reg) and post-reg in selected states. NCOP VSB and LT2 Lane Change tested.
In-House Development
Purpose-built components to support increased articulation and suspension travel.
Beyond ADR Strength
Fully computer designed, analysed and tested well beyond ADR strength recommendations without failure.
