I am considering the "drop diff" modification to the front end of 100 series IFS (2003 build) and would like some feedback from those who have been running this mod for a while.
Specifically a response would be appreciated in relation to any unusual wear on front driveshaft / suspension components and any affect the mod may have had on the already suspect 100 series radiator fan causing radiator damage during water crossings.

Comments also appreciated on any mods /methods to reduce the fan /radiator problem during water crossings.

Perry,

I've had the ATS4x4 suspension kit fitted since September last year. Handling has improved as has towing ability. The heavy duty springs hardly move when the Kimberley Kamper is hitched up.

There has been no appreciable wear on components since being done. I got the diff drop which brings all the angles back to factory - so in theory there should be no more wear than standard.

I can't comment on the water/fan situation. I've got an ARB delux bar with winch fitted. It has the intercooler guard and a plate which joins the bottom of the b/bar to the centre bash plate. This is where the three spacers are fitted which leaves a gap of about 30mm.

We haven't had much rain so the rivers aren't high enough to be a problem. After staring at the 'gap' for a while I decided to get a length of 50x3mm angle. I have cut out bolt holes that correspond to the bash plates and now mounted this. It's a bit hard to explain, but the angle goes accross the truck - E/W with the front part of the angle being vertical. This covers the gap in the bash plates and 'may' stop pressurised water from jetting up into the radiator. I haven't tried it as yet - that'll be at the end of this month. (I have photos but need can't post them here)

If I'm not happy with this then I'll replace the angle with a length of square tube, the same width as the spacers.

There are still gaps for water to jet through the bullbar but I think the alleged problem was the gap between the plates. Others have mentioned that a certain Sydney fitter removed the foam from around/under the radiator, hence allowing water to jet through with more force. I've checked mine and it is still there in the factory position.

Hope this helps,

PS - The photo of the camper in 'members rig' is BEFORE the suspension upgrade :-)

Darren McRae suspension mods are the way we went and couldnt be happier.
slow driving through the water and we had no problem last year in the gibb river, mitchell falls, kalumburu, cape leveque etc. towing a Tvan.

Hi Perry, I have had a W.A. suspensions diff drop kit with Bilstein shocks and Lovell Springs and torsion bars done on my 2003 T/D.

I'am wrapped with the performance difference and the overall lift.
Only thing was to do and extra wheel alignment check a month later once the suspension had settled.
Once I get a set of 285's all round it should look spot on.

Cheers Brooksie.
