Big-O-4x4 manufactures a range of Custom and replacement 4WD parts and accessories for any 4WD.

For any customised bracket, flange, manifold, infact anything that no-one else wants to build - then I'll do my best to make it for you. I offer competitive rates for CAD drawing and laser cutting of those odd ball and difficult to fabricate components.

 GQ & GU Swaybar Disconnect System. The all stainless steel sway bar disconnect system to suit GQ & GU Patrols. By lengthening one sway bar link pin to suit the installed lift on your vehicle - means that to get maximum wheel travel, only one side of the sway bar needs to be disconnected - unlike most other disconnects which leave your sway bar dangling down ready to be snagged on the first obstacle you come accross.
