King springs and Koni shocks

Two years ago we cracked the spring caps off the chassis on the Canning Stock Route. We had the chassis repaired and modified, but I noticed the other day that the one spring cap had a crack in it on top. The crack was not in a critical spot, but nonetheless it needed repair. The new Obieco box had to be removed so the work could be done, so I took the opportunity to do some other work including upgrading the suspension.

I have long gone with ARB springs and Koni shocks, and still recommend it for most 4WD applications, but the weight I carry and the extent of corrugations I travel over means I was looking for something a little more substantial. The guys at Kings Spring on the Gold Coast were most helpful when I visited them. I walked away with a massive set of rear springs made from 24mm, yes 24mm steel! These springs are huge and are made for extreme weights. King Springs will not allow them to be fitted to a Patrol unless the Patrol has chassis strengthening.

While the box is off the back a bit of work needs to be done

– adjust fitment of exhaust

-repair fuel tanks

– repair some wiring to trailer plug

– fit new springs to front

Note strengthening of spring caps
