3 Inch Block & U-Bolt Kit, 1978-79 Ford Bronco

Upgrade your vehicle's rear suspension with Rough Country's premium block and u-bolt kit. Our kits are specifically designed to provide a sturdy solution for sagging rears or adding lift height. Each kit features two fabricated steel blocks that reduce driveline angles, making them stronger than the standard cast block option.

• Tapered fabricated steel blocks reduce driveline angles and provide a more stable suspension system • Single 9/16-inch pin fits snugly into factory axle pad for a secure installation • E-coated corrosion-resistant steel u-bolts offer four inches of thread for easy installation • Heavy-duty design provides a sturdy replacement for the standard cast block option

Best of all, Rough Country's vehicle-specific kits are backed by our Satisfaction Guarantee!
