Last year we did our BIG trip Perth Ayres Rock Simpson Birdsville Fraser Island Cape York Gulf Kakadu Gurig Katherine Kunnunurra Broome Perth - In all 17,000 kms

Prior to the trip I had my Tough Dog Foam Cells replaced under warranty as they had failed.

I also had Polyairs fitted to support the extra weight and the Camper van. (My mate had big problems in his 80 series also towing his Camper Van crossing the Simpson - he had Polyairs fitted by ARB in Bundaberg and never had a problem after that.)

We travelled on some roads with fairly big rocks being thrown around under the vehicle. Consequently the lower part of the rear shocks have been badly dented and the shocks are now useless. Has anyone had similar experience and does anyone know if a guard can be fitted to shield the lower part of the shock absorber.

ARB make protective gaurds that mount on the rear trailing arms, this is meant to deflect any rocks from hitting the shocks that have been thrown up by the front tyres to.

Give them a call.

Did a simlar trip last year. I had OME shocks with the ARB guard fitted - works well.

How did the underside of your camper go? Our Aussieswag copped a hiding.

Thanks Gary

We had no problems with the underside of the camper
The Kimberley if fairly tough and the angled stone shield at the front of the camper deflects any rocks from the rear of the vehicle.

As we left Dalhousie, my mate with similar setup and Kimberley had a rock get caught in the disk brake on the Camper - jammed the brake on - sheared the bolts on the brake mechanism and ripped out the brake line. Crossed the Simpson without brakes and had it fixed in Bundaberg.

We use 2" poly pipe, cut in half long ways, and held on with one hose clamp. Only cover the front of shock.

Poly pipe should be available from plumbers, irrigation/pump suppliers. You'd only need 150mm to do 2 shocks.

Seen it all, Done it all.
Can't remember most of it.

Hi trekki. yes i have the same problem with mine. What i use is thick rubber mat and hose clamp to hold it in place and make sure it also covers the bottom bolt. It's a cheap way and works well.

Using poly pipe or rubber matting on a shock will cause it to fail under extreme conditions. A shock is just a big heat sink, it turns energy into heat thru its dampening action, if you wrap it up it will not be dissipate this heat and the heat build up will eventually melt the shocks seals.

Thanks for your replies - Looks like one of the following

ARB Shield
Poly Tube
Rubber Mat

Make sure there is air flow
