When I do the SAS somewhere in the future, I was thinking of using coils in the front. Anybody done this? Pros and cons?????Any pics?

I think the hardest part will be mounting the coils, expecially if you keep a toyota width front axle. A 3 link setup with track bar would be the simplest and shouldnt cause clearance issues. Maybe go to a wider front axle and coilover shocks, or use skinny coils that go outside the frame

A guy by the name of Ron Christainsen in Colorado, did the very thing you are talking about. He was featured in the FourWheeler mag under the title DROOP’n. He used coils for his front set-up and it flexed very well. He also said that it was hard to control on the road. BTW, he was running 9” of lift total (I think). I spoke with him in Las Cruces at the Chili Challenge and he said he was going back to leafs in front. He had custom coil-over shock mounts and used 2 lower control arms and one upper track arm. Since then, I think he has also lengthened the entire wheel-base by 6”. Anyway, there is a lot of engineering that goes into a coil front. Taking ideas from the soon to be extinct Cherokee, or early Bronco, Grand Cherokee, these all could help indeveloping your design. I see lots of R&D work though. Just my .02

dude i know you dont get them in the states, but you might like to contact JD of this board about it..........86+ toyota landcruiser bunderia front end is coil sprung and they swap straight into the ifs pick ups and 4runners. it is a axe of bolt on job and i think the only thing you need to do is drill 2 wholes either side of the frame to hold the radius arms.

Nick,

Just trying to work out the cheapest/easiest solution to obtain stronger CV's (birfields) for my HiLux. I will be sticking to a leaf sprung front end.
A FJ80 front end is approx 1625mm wide (wms to wms).
Do you know the width of the Bunderia?

Also wanted to swap in an IFS rear as I read it was 3" wider. However I read somewhere that it was 51 3/8" wide (1305mm). This does not sound right.
Do you know the width (wms to wms) for an 86+ IFS rear diff?

I tried searches but have had no luck.

The added advantage of wider track is that I don't have to run wheel spacers.

Regards,

Grant.

Dude just checked with my parts guy (dsi) and he said that the rears are 58inch on all 86 or newer.
bundera is the same as the full-size troopie and i have seen 1 fj40 with this gear swapped in, it was a little wider than the stock fj, i guess on a hilux it would be even wider. you should be able to cover it with flares.

NICK.

for more info put a post on the gutsquishers BB, someone in australia will have done the swap.

I would think that a decent amount of thinking one could got a bronko radius arm and coil buckets and fab em into the front axle but u-bolts would be a pain. Look at coilover rears and compare notes and just expect a diff to be in the way of one side. Lots of the members here have done coil rear.

I say...if your going sas anyway just look for a ford dana 44 front end. That way you could use radius arms, eithier wristed or just longer and ford coils. You would only have to fab up upper coil pockets and a panhard bar. Check out the ford section on por they have all kinds of ways of getting insane flex out of those ford radius arms.
