Description

The Moser Engineering A2864MUST axles are precision-crafted from 1541H alloy steel, a premium material chosen for its superior strength and durability. Each axle undergoes a rigorous manufacturing process, including forging in Moser-designed tooling, induction heat-treatment for enhanced torsional strength, and 100% magnaflux inspection to ensure a flawless, race-ready component. This meticulous construction makes them ideal for the demands of both high-performance street driving and competitive racing environments. Engineered as a direct fit for 1964-1966 Ford Mustangs equipped with either the 8-inch or 9-inch rear end, these axles offer a 28-spline configuration and a 5 x 4 1/2" bolt pattern. The included specifications detail a hub diameter of 2.430", a flange diameter of 6.00", and a bearing journal of 1.381". The axle lengths provided are 26 inches for the driver's side and 30 inches for the passenger's side. Options for custom lengths, different spline counts, altered bolt patterns, larger hub diameters for custom disc brakes, and flange machining are available upon direct contact with Moser Engineering. This package includes pre-installed bearings, studs, and retainer plates, offering a convenient upgrade. Customers can select their preferred stud length and bearing/retainer plate options to further tailor the axles to their specific needs. Moser Engineering also offers the flexibility to shorten these axles for narrower rear-end applications or to change the bolt pattern if required, ensuring a versatile solution for custom builds.
