Designed for Heavy-Duty Performance Complete Suspension Control
The CORE 4X4 Complete Rear Kit is a true performance upgrade that replaces weak factory components with premium, heavy-duty parts designed for extreme conditions. It eliminates rear axle shifting, instability, and excessive tire wear caused by improper geometry. This kit allows for precision suspension tuning to maintain perfect alignment under heavy loads while ensuring improved ride quality, smoother handling, and enhanced rear-end stability. Whether you're looking for increased towing capacity, improved trail performance, or maximum rear suspension strength, this kit provides the ultimate combination of durability and adjustability.
Two-Stage Powder Coating for Maximum Durability
To ensure exceptional corrosion resistance and long-term reliability, all aluminum components undergo a two-stage powder coating process. A zinc primer base coat prevents rust and enhances durability, while the top coat—available in 10 colors—provides customization and long-lasting protection.
