We rely on Moser Engineering axles, whether for high-performance street or all-out racing. These axles are made of forged alloy steel, then induction heat treated and magnafluxed. Custom axles are made for any application, length, or bearing size. Axles can be ordered with standard OE-style studs to replace original 35-40 year old units that have been stressed for many years. All axles come complete with pressed-on bearings, heavy duty flange plates and competition 3 inch studs. Please specify 28 or 31 spline axles. NOTE: True-Tracs require specific axle lengths, so please call and speak to a Cobra representative for assistance.
