hello all
posting up a different question from the normal "how to lift my MU" instead i would like to make my MU handle on tarmac better and be nicer to drive on long trips, im not looking at doing any high spped cornering just want to make my MU a little safer on the road and wet weather conditions, as most of my driving is done on tarmac and graded dirt roads now. i will also do some ocasional towing(rx7 race car or beetle race car)
current setup is nothing special just heavy duty peders 4wd shocks all round and peders leaf springs which have an extra leaf over stock i think. tyers are currently falken A/T on standard 16x245 rim, i will be looking for some good value for SUV tyres for these rims.
all advice appreciated

I trust you mean tyre size 245x16 which sounds about standard. You already have the heavy duty suspension which should be good on road but could be a little harsh in the ride comfort area. Fitting lighter shocks might help a little but at the expense of handling. Personally for what you want there is little to do the the suspension except maybe checking all the ball joints and bushes and replacing as necessary. For your stated use try changing to a HT type tyre. These are lighter in the sidewall and have a road oriented tread so should be much nicer. The Firestone RV has a good name but there are 1000s or other good ones as well. Remember HT tyres are not for off road except sand and even then not sand with rocks in. I like your choice of race cars. One of my brother in laws has a has a fwd beetle race car with the VR4 engine that was originally built for the Beetle cup in Germany.Its fully road legal. Another brother in law has done up a mid 80s beetle with 2.5 Subaru engine in the back that is very quick but soon to be turboed. My last brother in law is a life member of the Formular V club.

It sounds like you have already done the obvious upgrades so the sway bars would be the next step.
From experience Isuzu's wallow in comparison to Mitsi's and Toyota's so it would make sense that larger sway bars would help this. Once you've "settled" the suspension into a corner they seem fairly solid but i felt a LOT safer in my old Challenger cornering even though the grip level should be on par

From my experience putting a heavier rear leaf springs in and bigger torsion bars and heavy duty shocks is only going to make the ride harsher, like mine is now. I think maybe I should have left the normal springs in and put air bags in the back and adjusted the torsion bars when needed. But now to solve all your problems, sell the MU and buy a Wizard, the rear end has coils and the ride is 100 times better even after a new set of bigger springs were put in. I tow a 1200 KG caravan and the weight on the tow ball on the Wizard leaves it sitting higher than the MU. The ride in the Wiz is comparable to say a Falcon wagon when we are not towing of course. Cheers Bruce.

for sway bars you can get these. pureisuzu.com/sway_bars.htm but over 300US The bushes are all available individually but dont know if you can get a complete kit. With the swaybars something you could try on the cheap is a sway bar from a 89 - 91 jackeroo. No promises but they are likely to be stiffer due to the higher center of gravity and higher weight. They should bolt straight up but once again no one has tried this before so no garentees and all the usual disclaimers

i wanted to put michelin LTX AT 265/70 16's on my MU but after buying it i didnt have $370 a tyre at the time so settled on a good set of 2nd hand bridgstones the same specs, $100 a tyre 6-7mm i think.
i wanted michelins though cause we had such a good run on them on our work ute since new, the tyre guys were surprised when we went back for new ones, i think we got 130K out of the first set and they were still warrantable, the ute has done 200,500k now and still has 5-7 mm on the second set, and its not like we take it easy lol.
sway bar bushed sorted out my mates new ute, (and a new head + gasket and thermostat) lol i said buy a isuzu not a mitsy lol, interested to see how you get on.

Winding the front up seems to firm them up in the handling a bit. That and the HD springs in the back of mine and it handles tarmac fine. It even steers ok when getting sideways under power.

Anouther thing that will help for an on road only truck would be 19 inch rims and lower profile tyres. Maybe go extreme and put 22s on

Winding the front up seems to firm them up in the handling a bit. That and the HD springs in the back of mine and it handles tarmac fine. It even steers ok when getting sideways under power. Jimmy One thing I discovered recently while doing the front bushes is the front upper A- arm bushes need to be set when at rest. If you look in the wheel arch at the upper bushes, they have a large bolt running through the two bushes, with a nut and large washer at each end. If you take the nut and washer off you will find the inner metal sleeve of the bush is serrated, so as to lock in position to the washer. That is the bush is not free to rotate, but torsionally flexes the rubber. ..... So from that I think it is a good idea after a torsion bar wind or adjust, to while the suspension is at rest, slacken off those nuts to reset the bush.... then re tighten I think it made a difference to the ride... as winding the torsion bar shouldn't make any real difference.... still the same weight and forces acting on it.... just the neutral position is moved.

Prices change so much between time and supplier that listing this would be almost useless. As an example for a wheel bearing Holden 300 suppliers A 80 Supplier B 160 Bottom ball joint Supplier A 68 Supplier B 44 Holden dont know Center driveshaft bearing (bighorn) Supplier A and B 180 Holden 53.
