Leading A-Series engine specialist since 1981
Our AFS 'Advanced Fixing System' high tensile main bearing stud kit comes complete with a set of special waisted and centred studs for use with our four-bolt steel main bearing cap set.
Also included are our new forged 'AFS' multi point nuts and assembly lube to compliment the kit. Torque to 65lb/ft.
Please note that these are not suitable for use with standard main caps, only the MED steel caps.
The main cap fixing holes in the block may need to be deepened to ensure that the studs do not protrude from the top of the nut, or this will foul on the gearbox casing. Please contact us if you're unsure.
