Need a set of factory replacement u-bolts for your 2011+ Duramax 2500/3500HD or maybe something longer to accommodate a lift block or traction bars? These U-Bolts are available from stock length and up to 8" longer.
Each set of u-bolts will come with the following;
- X4 3/4" U-bolts with your choice in length
- X8 Heavy Duty Washers
- X8 Heavy Duty Nuts
Something to keep in mind when choosing length. You can always go longer in size, and cut off any extra thread that you have sticking out past the nut when properly torqued.
The u-bolt is measured from the underside of the u portion, to the bottom of the threads. For reference, factory is roughly 10.5" on the 2500HD and 12" on the 3500HD. When needing a factory replacement set, ours will be 11-12".
