1/4-Inch Steel U-Bolt Lift Blocks

The PMF Suspension fabricated lift block offers a robust solution for elevating your truck's rear end. Constructed from durable 1/4 inch steel and meticulously hand-welded, these blocks are engineered to provide a secure and stable lift. Unlike stacked blocks, PMF's design integrates the u-bolts directly, eliminating concerns about shifting or failure and offering a cleaner aesthetic. These lift blocks are available in 1/2 inch increments, enabling you to fine-tune your truck's stance with exceptional precision. They are designed to accommodate up to 3/4 inch u-bolts and feature multiple pin locations to assist in centering your axle within the fender-well. For axle centering, PMF's Adjustable Ubolt Top Plates are required and sold separately. The block height is measured at the center, directly over the axle, and various pinion angle options (taper) are available to help align your driveshaft, with taller lifts typically requiring more taper. Optional bumpstop tangs are available, which act as a contact point with the frame's bumpstop. However, on some lifted applications, these may not be functional due to tire-to-body interference. PMF also offers air bag tangs for inboard bag setups, though this requires custom mounting hole drilling. Custom length and larger diameter u-bolts, including bent-in-house options, are available, with 3/4 inch u-bolts automatically including new top plates. Please note that these lift blocks are considered a custom order item and are non-returnable. They are sold as a pair.
