The Speedmaster PCE287.1010 Main Girdle and 12-Point Main Stud Kit is engineered specifically for Ford 351 Cleveland engines with 2-bolt main caps. This kit combines a main girdle with high-strength 12-point main studs to dramatically improve main cap clamping force and reduce cap walk under high-performance and racing conditions, helping protect your bottom end during hard use.
Designed as a direct-fit solution for the Ford 351C Cleveland block, this kit is an ideal upgrade for street performance, strip, and track builds where added rotating assembly stability is a priority. The 12-point stud fasteners provide reliable torque retention and make installation and removal straightforward with the proper tools.
