// ABOUT ROCKJOCK 4X4

RockJock 4x4 is the house that John Currie built — home of the Antirock sway bar system that won King of the Hammers and the rebuildable Johnny Joint rod end that solved the flex-versus-street-manners problem for an entire industry. The catalog spans complete suspension systems, steering, and the CurrectLync heavy-duty linkage.

Everything RockJock makes is engineered by the Currie family's race program and manufactured to survive competition rock crawling, then detuned exactly zero percent for the consumer catalog. If it holds up at KOH, your weekend trail rig will never find its limit.

JAP carries 300+ RockJock components at wholesale-network pricing.
