rjc racing block girdle
Don't be fooled into thinking that the "chinese budget girdles" out there even compare to the quality and durrability of the RJC girdle. This girdle has been in the 8s on stock block cars and is the industry standard. For those of you who deserve the best instead of the cheapest. Basicaly you get what you pay for when it comes to bottom end strength and this is one area where it is not wise to scrimp. Be sure to insist on a genuine RJC girdle when ordering from other vendors.

This block girdle was designed with one thing in mind, strength. Made from 3/4" thick 1018 billet steel plate, flame cut out for rigidity, blanchard ground to ensure flatness then CNC machined to exact tolerance. This girdle is 100% made in USA.

This girdle is designed, manufactured, sold and tested in house, by true Turbo Buick enthusiasts.

This girdle was specifically designed to allow the back yard mechanic to be able to install it, not just the professional engine builder.

Here is the girdle being checked by by one of our Cordax Measuring Machines. This machines accuracy is guaranteed to within 0.00005. (50 millionths)

This ensures a perfect fit every time.

This is the billet aluminum pickup tube extension that is included in the kit. It comes with the mounting hardware and two  extra gaskets.

This eliminates the troublesome task of extending the pickup tube.

This is a girdle installed on Jason Cramer's block, the engineer that designed it. He and his dad, Tom have built many girdled motors since this one.. This engine produces over to 700 hp and propels Jason's GN down the quarter mile in 9.77 @ 139 This is in a full weight, t-top car with all of the accessories and A/C at 3620 lbs. We have customers cars with stock blocks running 8.90s at over 156 mph reliably.

The girdle comes with all of the mounting and installation hardware required. We use ARP® and grade 8 fasteners.
