I'll be throwing a new axle under my truck in the weeks to come once I do the seals, put in a trac loc, and stang brakes (upgrading to 8.8 from a 7.5). While im at it Im going to buy an add a leaf kit ( Tuff Country 85350 - Tuff Country Add-A-Leafs - Show All - SummitRacing.com ) and i would just like to know what size u-bolts i need if i put these or if stock, what specs / size should i be looking for?

 

28-spline 8.8, right? If so, I recommend these: U Bolt, 5/8" x 2 3/4" x 10" [UB275] - $13.25 Just cut the excess off.

 

correct. Thanks a lot.
