Who is Formula 4x4
Comfort. And control.
Formula 4x4 is Australia’s specialist in comfortable, capable 4WD suspension. Developed in-house by Australian enthusiasts with over 45 years of aftermarket expertise, every kit is engineered and rigorously tested across the country’s toughest conditions, from sealed roads and daily commuting to desert tracks, beaches, and heavy touring.
Comfort is at the core of the Formula 4x4 design. Progressive-rate springs and carefully matched components deliver a supple, compliant ride around town while remaining controlled and capable when the going gets rough or loads increase. Whether you’re after more clearance, better load-carrying ability, or simply a more refined drive, Formula 4x4 kits are built to improve the experience without compromise.
