- Heavy-Duty Construction for Maximum Strength – Made from robust steel tubing, ensuring long-lasting durability and improved resistance to off-road impacts.

Built for Lifted and Stock Vehicles
If you’ve lifted your Toyota 4Runner, improper axle positioning can cause handling issues, uneven tire wear, and drivetrain stress. This kit allows for precise axle centering, pinion angle correction, and optimized suspension geometry, ensuring smooth handling and improved drivability at any lift height.
Dual-Stage Powder Coating for Superior Durability
Each component in the Cruise Series Rear Kit undergoes a two-stage powder coating process for enhanced rust protection and corrosion resistance. The zinc primer base coat forms a barrier against the elements, while the top coat—available in 10 color options—adds a personalized, durable finish.
