Trekline Motorsport's Rear Lift Blocks provide an excellent way to lift the rear of your vehicle. These lifting blocks not only look great but are incredibly strong and will stand up to the elements. Many companies out there are selling Aluminum lift blocks which will crack and deteriorate over time. Stick with a heavy duty steel block for the superior strength and longevity.
These blocks are 4" thick lift blocks. That means they have an average height of 4 inches thick. The blocks are Tapered so the front measures a little lower and the rear measures a little higher. If your vehicle has a stock block from the factory and you plan to replace it, you will want to use a block that is taller than the stock block by the amount you want to lift the truck. (Ex: 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 give the lift you want).
These blocks are for trucks with 2.5" wide leaf springs. We do not recommend running them on applications with 3" wide leaf springs.
