Testimonials
“The 3-inch lift and track correction completely transformed my 79 Series. It finally feels stable on the road and unstoppable off it, with the added bonus of being street legal and engineered properly. The 4200kg GVM upgrade means I can load up for work or touring with confidence.”
“The Foam Cell PRO shocks are unbelievable on the 300 Series. Smooth on the highway and tough in the bush. With the 4050kg GVM upgrade, I can carry the gear I need without worrying about weight limits. It’s the upgrade every 300 owner should consider.”

“I tow a heavy camper with my Ranger, and the 3,650kg GVM upgrade has been a lifesaver. The Foam Cell PRO shocks soak up everything, even when fully loaded. It feels stable, capable, and ready for anything I throw at it.”
“The ORI 3.5-inch lift paired with Fox 2.5 shocks has turned my Chevy into a beast. The 4,250kg GVM upgrade and 35-inch tyres give me the stance, clearance, and carrying capacity I need. It’s the perfect mix of comfort and performance.”
“My Ram 2500HD is now the ultimate tow and touring rig. The 5,300kg GVM upgrade means I can legally and safely haul heavy loads, and the Fox 2.5 shocks smooth out every bump. Sharp 4×4 absolutely nailed this build.”
