Forged from a billet piece of chromoly 4150 then a rigorous heat treating process to result in the same tensile and yield strength as BIS80, with a higher ductile factor ensuring the material is elastic and able to bend further than BIS80 before terminal failure. Designed for 3" + lift, this kit offers around 5 degrees of castor correction @ 3" and moves the diff forward approximately 15mm. SPECS Increased caster - suits 60mm to 100mm lift Newly designed Pivot Box for increased ground clearance over standard Drop Box design - improved clearance over factory. NOTE : GU owners with the big spherical bush on the chassis end of the Panhard (Typically S2 onwards) may require extended bump stops to prevent the radius arm/bolt from fouling on the panhard mount on BIG bumps/hits. They will not hit under normal driving conditions. To fit a sway bar to these arms you will require a spacer in order to clear the front drive shaft. Sway bar spacer kits are available here. Freight quoted includes all major capital cities within Australia.
