Upgrade your vehicle's suspension with Trekline Motorsports Rear Lift Blocks, designed to provide an exceptional way to elevate the rear of your vehicle. These robust steel lifting blocks not only boast an attractive appearance but also offer unparalleled strength and durability to withstand the elements. Unlike many aluminum lift blocks on the market, which can crack and deteriorate over time, our heavy-duty steel blocks ensure superior longevity and performance.
These 5" thick lift blocks feature a tapered design, with the front measuring slightly lower and the rear measuring slightly higher. If your vehicle has a stock block from the factory that you plan to replace, be sure to choose a block with the appropriate height to achieve the desired lift. For example, if there is a 2" factory block and you want to lift the truck an additional 2", you would need a block measuring 4 inches thick to replace the factory block and still achieve the lift you want. Choose Trekline Motorsports Rear Lift Blocks for a reliable and long-lasting suspension upgrade.
These blocks are designed for 2.5" - 2.75" wide leaf springs. Not Recommended for vehicles with 3" wide leaf springs.
