Ford 351w MAIN CAP GIRDLE.

AUSTRALIAN Designed and MADE

Suits all OEM and aftermarket  351 Windsor blocks with a 3.00" Main.

Will accept up to a 4.25" stroke crank without modification.

Includes 10 x 8mm CNC machined Spacers to clear the 'hump' on the main Cap. 

Clears Oil Pump, may require sump modifications on some models. 

Designed and Manufactured here in Australia using the latest CNC laser Cutting Technology, from 6mm thick M350 Steel. It has been precision ground on both sides to ensure flatness. It has a very similar expansion rate to that of cast iron and 'will not spread' your main caps like an ALUMINIUM girdle.

This quality product ties your main caps together to help eliminate cap walk. It also distributes harmful 'Harmonic Vibrations' across the entire cap set rather than just 2 caps either side of a rod bearing pack. This product is a must in all Stroker, Turbo, Supercharged, Nitrous and high RPM applications. 

Our girdle is a simple creation and is carefully designed to cater for lateral movement of the main caps for most extra duty applications. It has been made of 6mm steel to; minimise stud length, oil pan clearance issues, and (flexible enough) to take up any small variations in cap heights, and of course extra engine weight. Any thicker is unnecessary, as a girdle would have to be at least an inch thick to add to the structural integrity of the block itself ( if your thinking that a girdle actually strengthens the block). However thicker girdles can be supplied, if requested, and a longer delivery time is required.

The Installation of Main Studs is HIGHLY Recommended. 

I use and supply ARP main stud kits.

The Kit for this application is an additional $279.00

If you require studs please contact me before you select 'Buy it now', thank you.
