These fittings are 100% stainless steel. The angle fittings are made from s/s forgings. These fittings are designed to connect to stock, late model fuel injection fuel lines, both the inlet line and the return line. Many of these fittings are supplied as part of our Fuel Rail Kits but we also offer them separately for those enthusiasts who are doing a custom fuel line installation. All of these fittings, except the 52185 and 54187, have 3/8-NPT male threads. The 52185 has -6AN threads and the 54187 has 1/4-NPT male threads. The 52185 can be useful if you are running a -6AN fuel line from your fuel rails and need to connect to the stock fuel inlet line. The -6AN part of the fitting threads into a -6 hose end on a fuel line.

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.
A Professional Products Stud Girdle Kit will keep your rocker arms in line. Without a girdle, the rocker studs can flex back and forth which robs horsepower due to inaccurate valve timing. Our Stud Girdle Kit firmly clamps all the studs together resulting in more horsepower through elimination of flex.A.580-inch diameter seat sits on the rocker ball for better retention. Internal set screws (3/8 or 7/16) provide secure locking. Note: Use of this kit requires tall valve covers.

NOTE: Dimension “A” must be 1.773" on your cylinder heads in order for this kit to fit. Will not fit heads with 1.807" spacing on stud pairs.
