Winding the Torsion bars up will increase the angle on the CV joints & limit the available down travel effecting both the handling & wheel travel. A diff drop kit raises the front of the car leaving the suspension where it should be.

How does a diff drop kit raise the car?????
The diff is mounted rigidly to the chassis. All the diff drop kit does is lower the diff hence reducing the angle of the drive shafts. Ideal when you raise the vehicle.

Yes you are right 120. After rereading my reply I was wrong. The kit still needs the torsion bars wound up. It just fix's the CV angles.

Mark,

ATS4x4 in Geelong, Vic, did mine with the diff drop kit (Suspension upgrade) - you can also get the diff drop bracket and bolts from Snake Racing - check out their web site for price.

Hi Guys,
Diff drop only drops the diff, doesnt change the front geometry at all, still have the issues with limited down travel. The purpose of the diff drop is to keep the driveshaft angles reasonably straight so you dont chew out CV boots and ultimately your CVs will last longer.
To increase the droop you need to change the shocks to a longer one as far as I know. Need to have a minimum of 60mm of droop is what I have found to be the general consensus, but opinions will vary.

Some replace the torsion bars and some don't.

At a bare minimum I would purchase the ARB support brackets and weld them to the control arms. Inside the control arm where the torsion bar mounts, there is a crush tube. I would weld around this as well.

I would replace them with the after market ones especially if you are going to uprate the spring rate of the bar.

I have fitted Darren's from ATS drop kits and they are a nice, well made kit. No affiliation. I just fitted it to a customers vehicle.

The 100 series IFS cracks the control arms where the torsion bar adjoins. The support brackets bolted will aid but if they are welded, the strength is increased two fold. It consequently doubles the thickness of the steel around the control arm. As for the crush tube. When you look at them once removed from the vehicle, they are only held in with a pitiful spot type weld. If some movement is allowed, like on full suspension travel when the control arm is allowed to flew, failure could possibly begin to occur. If it was mine I would weld it to be sure.
Just my thoughts and opinion.
You will have to email me direct for pricing as I don't like advertising on forums.
I purchase the drop kit from Darren at ATS and then fit in my workshop.
You can get my contact details from my rig profile.

As I said before, these are my opinions only. What you need to do is consider all the opinions offered on this forum and then decide which best suits your needs. I am happy to discuss this further directly if you want to.

Cheers

It should read "when the control arm is allowed to flex, no flew"
Sorry for the typo.

I originally had the dealer wind up the torsion bars but then bit the bullet and went the ATS setup. A huge improvement both on and off road. If you have the diff drop done make sure the bash plate is reset hard up against the radiator.
