Description
Steel Centre main strap for large bore engines, comes with longer high tensile bolts. Main top cap needs machining flat, no other modifications required.
On all performance A series engines, it is essential to ensure accurate and as near permanent location of the Centre main bearing of the crankshaft as possible. Flexure allowed here, especially at sustained high RPM levels, can cause spun bearings, crank or main cap breakage with severe or mortal damage to the engine. This item is NOT suitable for Cooper S blocks.
We also stock the MED High Quality Centre main strap and AFS stud kit for high performance 1275-based engine builds.
