Tech Insight

Steel AntiRock arms are a solid choice for rigs that prioritize durability and predictable handling over weight savings. The shorter 17" length compared to TJ/LJ arms makes them ideal for tighter front suspension packaging commonly found on XJ and MJ platforms. Pairing these arms with RockJock’s double shear end link bracket kit adds leverage tuning and offset flexibility without sacrificing strength.
