Main Cap Girdle Chrysler


Main cap girdles designed for ultimate bottom end strength.

SKU: TW117 Category:


Available for 331 354 and 392 Chrysler.  No additional machine work needed.
A very cost effective way of adding extra strength to your bottom end, without the cost of 4 bolt mains. Dyno tests have proven the cost effectiveness and added rigidity. Helps prevent dreaded cap walk in high horsepower applications.  This girdle is my original design 9 bolt series, and includes both a spacer package and ARP main studs. ( please note that some applications require the 2 provided ARP main bolts to be used on the rear main cap for clearance issues)
Take a moment to view the last two pictures. This is a jr. fuel engine that lost a connecting rod. With my girdle installed, the damage was limited.  The girdle contained the broken rotating rod.
