This main plate girdle will hold the bearing caps on your 7.3L Ford Powerstroke more rigid from higher torque to help prevent block twist and keep your main bearings in line.

The longer studs are for the center holes and shorter studs are for the outer holes. Please refer to ARP installation instructions in the documents tab to proper torque specs on the studs.

Before installing this plate on your engine, use a calibrated straight edge across the top of the main caps to be sure they are all the same height. Some main caps may be higher and should be surface ground to the tops of the caps are all true/in-line so as to no distort the plate.

Majority of the time the caps are very close to being true across. The oil pickup tubes can vary quite a bit on how they were bent from the factory, so you might have to adjust it.

If you are unsure of installing yourself, seek out a competent and qualified technician to install this kit.
