Do it Right!
When installing any lift/leveling kit on leaf springs, you may find that your stock u-bolts may not be long enough to be compatible with your new setup. Even if you are able to get the nut on, you may not be able to get enough thread engagement for the assembly to be considered "safe." That's where Rocktrix extended u-bolts come in. Made to work with any lift kit between 1.0" to 3.0", our u-bolts will ensure that your ride is safe and reliable for whatever journey on which you want to go.
- Extended U-bolts (Square Bend) ensure proper thread engagement when securing your lift pack and leaf springs to the vehicle.
- Increased reliability and safety when used with a lift kit.

These U bolts are tiny. They may be long enough but they are not large enough diameter to go on your truck, not even close.

This item was supposed to fit a 2002 Chevy 2500 HD. Diameter of bolts did not match existing bolts. Contacted an axle & frame shop and were advised not to use them. Returned for a refund.
