Tuff Country Rear Axle U-Bolt Kit for Select Chevrolet/GMC 1988-2010 (4-inch Lift Blocks) - 17857
$68.89
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1988-2010 Chevrolet and GMC K1500, K2500, Silverado, and Sierra models equipped with 4-inch rear lift blocks.
Tuff Country rear axle U-bolts are engineered specifically for trucks with aftermarket suspension lift kits. When installing 4-inch blocks, factory U-bolts are too short to safely secure the axle to the leaf spring pack. These extended-length U-bolts provide the necessary reach and clamping force to maintain suspension integrity. Each bolt is zinc plated for superior corrosion resistance, ensuring durability against road salt and moisture.
- Designed specifically for vehicles using 4-inch rear lift blocks
- Zinc plated finish for maximum corrosion resistance
- Includes four (4) U-bolts with required nuts and washers
- Direct replacement for undersized bolts in lifted applications
- Manufacturer Part Number: 17857
