Moser Custom 1541H Alloy Axles are without question the best in the business. They begin with premium quality alloy steel that is forged in Moser designed tooling, induction heat-treated to optimize torsional strength, and 100% magnafluxed. This process not only gives the axle the strength of a race only axle, but makes it ideal for street use as well. The axles are specifically designed and engineered to take the stress and strain of both racing and high performance street uses. Their axles are available in any spline count and can be made to fit virtually any rear end setup. All popular bearing sizes and bolt pattern combinations are available. If your future plans call for a narrower rear, Moser Custom Alloy Axles can be shortened and resplined to fit your needs and bolt pattern changes can also be made.
