High-Strength Main Cap Security for GM Rear Ends

The Moser Engineering Main Cap Stud Kit is a critical upgrade for anyone building a high-performance GM 10-bolt or 12-bolt rear end. When you increase horsepower and torque, the factory main cap bolts can become a weak point, potentially leading to cap walk or catastrophic failure. This stud kit replaces the standard bolts with high-strength chromoly studs, providing superior clamping force and stability for your differential main caps.

Why Use Studs Instead of Bolts?

• Superior Clamping Force: Studs provide more consistent and higher clamping pressure than traditional bolts, ensuring the main caps stay securely in place under load.
• Chromoly Construction: Manufactured from high-strength chromoly steel with a black oxide finish, these studs are designed to withstand extreme stress without stretching.
• Prevent Cap Walk: By providing a more secure anchor, these studs help prevent the main caps from moving, which is essential for gear longevity.
• Versatile Fitment: Specifically designed for GM 10-bolt and 12-bolt rear ends, offering a perfect fit for a wide range of performance applications.

Whether you are building a drag car, a street/strip machine, or a high-torque truck, securing your main caps is non-negotiable. This kit gives you the peace of mind that your rear end internals are held together by the best hardware available.
