This flat U-bolt kit fits Mack leaf spring axle applications and is built as a replacement for the OEM hardware. Sold as a 2-pack, each kit contains one flat U-bolt and two nuts for clamping the spring plate to the axle housing. The flattened bolt ends help reduce stress points at the clamp area and keep suspension alignment steady.Interchanges:Mack 6QK3114P54Mack 7QK3118P54Mack 7QK3150P10Mack 7QK3150P12FUB-4795This unit is sold in packs of 2.FeaturesSold as a 2-piece packEach kit includes 1 flat u-bolt (FUB-4795-001) and 2 nuts (ANU-5835)Nut OEM 21AX405Suspension category hardware, fasteners and fittings partTech SpecsSell pack: 2 pieceKit contents: 1x Flat U-Bolt (FUB-4795-001), 2x Nut (ANU-5835)
