Never worry about the bottom end holding together again! Adding our new girdle kit to your Mopar will greatly increase its strength. Illustrated instructions  are included. The Big Block girdle ties the main studs into the pan studs and block skirt area, too, and there is no machine work required. The kits are supplied with studs for their superior clamping ability. When installing studs, the block must be line honed, unless it was previously line honed with studs. Using longer studs will not alter the main bore alignment. This kit will require that your block either has been, or will be line honed with main studs.

Customer Testimonial:   "Just a little background so you'll know who I am. I am a 60 year old Dodge fart  who has forgot more than most of the guys ( I call them magazine mechanics) will ever learn about Mopars.  FYI...your girdle works!  Dyno at 8500 RPM for 15 seconds. 2 bolt main Mopar crank, 746 HP & 676 ft/lb of torque. Shhhhhh.... don't tell anyone. I pulled the bearings and they look perfect. No cap walk at all. "      Hull Motorsports   Ellenwood,Ga
