This flat U-bolt kit fits Mack suspensions and is sold as a 2-piece pack for a complete installation. Each kit pairs one flat U-bolt with two nuts, giving the hardware needed to clamp the axle housing to the spring plate. The flattened bolt ends help reduce stress points and keep suspension alignment true, and the kit is built as a replacement for the OEM hardware.Interchanges:Mack 7QK3118P44Mack 7QK3150P7FUB-4804This unit is sold in packs of 2.FeaturesFlat U-bolt kit, sold as a 2-piece packIncludes flat U-bolt (FUB-4804-001)Includes two nuts (ANU-5835, OEM 21AX405)Suspension Parts categoryTech SpecsKit contents: 1x Flat U-Bolt (FUB-4804-001), 2x Nut (ANU-5835)Sell pack: 2 piece
