Improve rear ride height and suspension geometry with Zone Offroad ZONU3021 2-inch cast iron lift blocks. Designed for leaf spring trucks, these tapered blocks raise the rear of the vehicle while helping correct pinion angle after installation. The durable cast iron construction provides reliable support for off-road and everyday applications, while the black finish helps protect the blocks against corrosion and wear.
The Zone Offroad ZONU3021 lift blocks use standard 5/8-inch male locating pins with 11/16-inch female openings for secure alignment between the axle and leaf spring. Each block is CNC-machined to ensure accurate pin placement and consistent installation. The tapered design is intended to improve driveline alignment, making these blocks a practical choice for suspension lift projects that require additional rear clearance and proper pinion positioning.
These rear lift blocks are finished with a black powder-coated surface and cast in the USA. They are sold as a pair and are designed for compatible leaf spring applications, including 1978-1987 Ford Bronco models. Verify vehicle configuration, spring design, and required installation hardware before purchase. Professional installation is recommended to ensure correct fitment, alignment, and safe suspension operation.
