You asked for it we responded. Head bolts for every Harley engine including S&S and all aftermarket manufactures. Four style heads are available with three available for every engine application. We even took the design one step further to give you a cleaner look on S&S engines. Original equipment head bolts from S&S all use a washer, either .100” or .250” in height. They need to do this because of the small flange on their head bolts in contrast to the large flange on the original equipment Harley head bolt which does not use a washer. With a large flange on all of our head bolts we were able to make head bolts for S&S applications that use the .100” washer shorter by the same amount so no washer is needed. There for our head bolts will not sit up high in the cylinder head giving you a cleaner low profile look. For the applications that use the .250” washer we supply a .150” stainless washer.
- Manufactured from 630 stainless
- Heat treated to 180,000psi tensile
- Extra deep broach eliminates "rounding out"
- Hand polished to a mirror finish
