These are custom blocks for the Titan that are the proper width and offer an offset pin to bring the axle forward about 5/8". These are fabricated from steel plate and powdercoated black. These are very strong and wont crack like some cast blocks but also light weight. There is a slight taper in these that works well on the lifted applications. Ubolts are grade 8 and extra long and should be trimmed to length after install. Price includes shipping in the 50 states.
