This flat U-bolt kit fits Mack suspensions and comes as a pack of two complete kits, each with one flat U-bolt, two washers, and two nuts for a full hardware set. The flattened bolt ends help spread clamping stress evenly across the spring plate to keep the axle housing properly aligned. It replaces worn or damaged U-bolt hardware on the axle-to-spring connection.Interchanges:Mack 6QK3123P8Mack 7QK3131AP8Mack 7QK3154P8This unit is sold in packs of 2.FeaturesSold as a pack of 2 complete u-bolt kitsEach kit includes one flat u-bolt (FUB-4775-001)Each kit includes two washers (FWA-0180)Each kit includes two nuts (FNU-4719)Suspension Parts categoryTech SpecsKit contents (per kit): 1x Flat U-Bolt (FUB-4775-001), 2x Washer (FWA-0180), 2x Nut (FNU-4719)Sell pack: 2 kitsUnit of Measure: Pack of 2
