Key Features
These arms feature RockJock’s 2 1/2" Johnny Joints, the original and most durable high-articulation urethane suspension joint on the market.
Johnny Joints feature a smooth steel ball that pivots inside a proprietary urethane shell to provide over 30 degrees (per joint) of quiet, shock dampening articulation - without the excessive deflection found in soft rubber-based “flex joints”.
Johnny Joints deliver a smooth, comfortable on-road ride with the ultimate in off-road capability.
They are so trusted, that they are used by multiple commercial suspension companies, for both street and off-road suspension systems.
Arms are fully greasable via zerk fittings.
Finish is semi-gloss black powder coat on the arms and gold zinc plating on the Johnny Joint adjuster ends.
