Rancho’s heavy duty extended cast ductile iron steering knuckle maintains optimal steering geometry and allows for precision alignment. Steering integrity is uncompromised by maintaining the stock location of the factory rack and pinion steering. Combined these features improve handling and eliminate bump steer. Ranchos exclusive high clearance one-piece sub-frame adds superior strength and stability to the vehicle and also precisely relocates the lower control arms and differential. The positioning of the differential is calibrated to correct both CV and drivetrain angles. This ensures a vibration free ride and protects components against premature wear. This system also allows for the use of the stock wheels and accommodates fitment of 35" or metric equivalent diameter tires. No drivetrain or exhaust modifications are necessary making this a complete bolt on system. The rear height is set to what Rancho considers the perfect level with new rear spacer blocks with integrated bump stop pads.
