DMR-22361-1 5 cap halo girdle is made from 1/2" thick steel for S/B. This halo girdle will stabilize main caps 1 thru 5 to help prevent main cap walk (flex) which will lead to premature main bearing and crank failure. Will work with DMR-5942 billet main bearing caps. Will fit stock pan and all aftermarket pans but not Toro pan. Fits 307-330-350-403 Oldsmobile engines. 1 thru 4 main caps will need to be cut to 2.17" in height. DMR-5942 main billet caps are already made to 2.17". Will accept DMR-5850 full length windage tray. Also needed is DMR-5301-2 (.125") rear pan baffle to bring the rear cap height up to the same height as the other 4 caps.
 
DMR-22361-2 5 cap halo girdle is made from 3/8" thick steel for B/B. This halo girdle will stabilize main caps 1 thru 5 to help prevent main cap walk (flex) which will lead to premature main bearing and crank failure. Will work with DMR-5943 billet main bearing caps. Will fit stock pan and all aftermarket pans but not Toro pan. Fits 400-425-455 Oldsmobile engines. 1 thru 4 main caps will need to be cut to 2.5" in height. DMR-5943 main billet caps are already made to 2.5". Will accept DMR-5850 full length windage tray. Also needed is DMR-5301-2 (.125") rear pan baffle to bring the rear cap height up to the same height as the other 4 caps. 

Use a 5 cap halo girdle up to 600 HP. Anything larger that 700 HP should have a full pan rail girdle. On a 403 because of the windowed main webs subtract 100-200 HP from the above numbers.
