5" Rear Block (2-Leaf)
Does the rear of your truck need a little extra boost? The BDS Add-a-Leaf kits are the perfect answer. This kit comes with complete instructions, new center pins, and new leaf alignment clamps. Order one kit per axle. Add-A-Leaf kits are sold as pairs except for dual add-a-leaf kits which are sold in sets of four.
U-bolts are not included in add-a-leaf purchases but are listed here for reference. The u-bolts listed may be longer than necessary for add-a-leaf installation. U-bolts sizes were based on maximum OE leaf packs which can vary widely due to towing packages, GVWR variations, etc.
