89-02 5.9L 12/24 Valve Cummins Modified Block Stiffener Girdle Kit [HMPModGirdleKit]

Recommended for High HP high RPM motors. Will improve ring seal under strenuous load conditions such as sled pulling or drag racing due to overall stiffening of the block.

This kit requires the use of extra-long main studs to integrate the mains, OR you can use standard main studs and this girdle will clear without modification, but will not integrate the mains into the girdle.

Kit includes:
1-Modified Block Stiffener/Girdle
2-Pan Gaskets
*Pan Bolts, Long
2-Suction Tube Gaskets
36-Long Pan Bolts
2-Long Oil Sump Bolts

The stock girdle bridges have been removed and replaced with new laser cut bridges made to clear the HD 12PT nuts on the main studs and have holes that allow the XL Main studs to come through to tie the mains to the block.

Girdle thickness is just under 3/16th's.

Specially modified & welded by Kurt Haisley.

Availability may vary, these girdles are made in batches, please call for availability.
