Front and Rear Axle

They are conventional 4340 torsion bars made by Sway-A-Way for Nissan Motorsports. The bars are 26.5 mm in diameter and are larger than OEM torsion bars, which are 24.5 mm in diameter. They are approximately 30% stiffer than stock. Comes as a set of two bars, generally painted with a white epoxy.

Axle wrap occurs usually on vehicles with the softer leaf springs commonly used for either a cushy ride or maximum articulation. As power is given to the rear axle in soft sand, the tires begin to grab. The springs twist into an S shape until they tighten up to the point that the force overcomes the traction. The spring "unwraps", causing a loud banging noise and causing the rear end to actually hop off the ground as the spring uncoils. It has been known to cause broken axles, especially in higher hp vehicles.
