Stud Girdle Kit and parts - Proform GM

The Professional Products Stud Girdle Kit for small block Chevys is one of the most advanced kits in the industry, yet is very competitively priced. Featuring precision die cast aluminum alignment bars with all other parts made from 4140 heat treated steel, this is a top quality kit, well suited for the professional engine builder as well as for the do-it-yourself enthusiast. This Stud Girdle Kit is the lightest kit of this type (bars are 23% lighter) yet is 20% stiffer than kits with solid aluminum bars. This kit won't fit Chevy factory aluminum heads. It will fit Brodix, World, AFR, Edelbrock, and others. The vast majority of small block Chevy cylinder heads utilize the 1.773-inch spacing between rocker stud pairs. Chevrolet factory aluminum cylinder heads have a 1.807-inch spacing between rocker stud pairs and this kit, and competitive kits, will not work on those heads.

Stud Girdle Features:

  • 23% lighter than solid bars
  • 20% stiffer than solid bars
  • Includes 16 adjuster nuts
  • .580” diameter nut seat
  • Spring loaded
  • Very affordable
