Industrial Injection Gorilla Girdle



Click for verification of this site


The purpose of the engine main bearing girdle is to increase block rigidity and tensional stiffness. It does this by joining all the main bearing caps and oil pan rail together. Industrial Injection girdles are designed by using the latest CAD software and machined using a CNC milling machine and lathe.

Engines that use a main bearing girdle make more power, by decreasing friction in the main bearing bore and overall alignment of the piston and crankshaft bores. The main bearing girdle will strengthen and stabilize the bottom end of the cylinder block evenly distributing the load across the main bearing caps virtually eliminating main cap walk. The 14mm girdle is being used on engines producing well over 1500hp. All hardware is included for installation.

  • Increase block rigidity and stiffness
  • Stabilize & strengthen bottom end
  • Complete kit ready for install
Clearance Modifications to the oil pan are required when using 14mm Gorilla Girdle Kit.
