Construction & Design

The ARP Mandrel Bolt Kit is meticulously engineered using ARP's proprietary 8740 chromoly steel, a material known for its exceptional strength-to-weight ratio and fatigue resistance. The shot-peened finish not only enhances durability but also provides a smooth surface that resists corrosion and galling. The bolts feature a precise undercut design that allows for optimal stretch and preload, critical for maintaining secure connections in high-performance environments.

The 12-point head design facilitates easier installation and removal, especially in tight or hard-to-reach areas. The extended length and full thread engagement ensure that the bolts can handle the stresses of high-performance driving, off-road use, or heavy-duty applications.
