The ReadyLIFT Rear Block kit will safely raise the rear of your 2500HD Trailer Package by 1". This kit is based on OEM designs and is never made out of lightweight extrusions. To ensure maximum strength and durability, these blocks utilize cast-iron construction. By adding this block, you will gain a slight rake back on your truck which is ideal for hauling or towing.
