Industrial Injection Gorilla Girdle 4BT Cummins RMG2G14MM-4BTFor the guys out there wanting to run higher horsepower out of their 4BT Cummins, the Gorilla Girdle from Industrial Injection is what you need. Under high RPM with higher horsepower engines the block itself will actually flex. This causes main cap walk and improper alignment of the piston and crankshaft bores. The Gorilla Girdle strengthens and stabilizes the bottom end by evenly distributing the load across the main caps with consistent clamping
For the guys out there wanting to run higher horsepower out of their 4BT Cummins, the Gorilla Girdle from Industrial Injection is what you need. Under high RPM with higher horsepower engines the block itself will actually flex. This causes main cap walk and improper alignment of the piston and crankshaft bores. The Gorilla Girdle strengthens and stabilizes the bottom end by evenly distributing the load across the main caps with consistent clamping force via included ARP main studs.IMPORTANT NOTE: This kit includes 14mm studs, which are found on the majority of 4BT engines. In some cases on newer 4BT engines, we have seen 12mm bolts. In this case, you will have to drill and tap the block to accept the 14mm studs. If you do have the 12mm bolts and wish to not drill and tap, please contact us, as we can typically have Industrial Injection build the girdle to accommodate 12mm ARP main studs.

Essential for new pups.
Heartbeat toys are the best when welcoming a new pup home. The heartbeat really calms them, and they carry the toys around forever! We have several, and all of the kids love them.

This works better than any other product tried
This is the best. I had tried hemp chews, chamomile and lavender ointment, and thunder vest. And at times all three for my dogs anxiety during storms and any loud noise. Nothing worked. Got this and it calmed him almost immediately and actually calmed him so much he just fell asleep. Glad I ordered two. One for upstairs and down. It’s very cute and soft. Great product with a great price. It’s holding up good so far. Only had for a couple of weeks. Hope it holds up for awhile. As he is not a chewer.

Its amazing
My dog calms down when I put her plush toy near her; when I hear the sound of its heartbeat, I know she's very still.
