Hey guys. What's the go with falcon rears and rears up front? Pros and cons? Seems to have good flex. I am running 2" body lift, 3" suspension on new heavy duty springs. They are too stiff and my flex sucks. What do you rekon?

good articulation but its a bit more to it than rip the old springs out and bolt the new ones in on the driveway on a Saturday morning

if your new heavy duty springs are too stiff which is what you'd expect from a new set of heavy duty springs you could try playing around pulling a few leaves out it wont cost you anything other than a bit of time and some blood sweat and tears but don't try pulling too many leaves out and making them too flexy or you'll end up bending them with a bit of RH Jandel and also risk shearing the diff pinion if the axle housing can twist/torque around too far what brand springs are the new HD springs you put in there?

Ive got the same in mine hd lift springs 3" ive taken a leaf out of the fronts ans one out of the rear still have the height and more flex mine is a single cab so is really light.

Start by taking out the shortest leaf on each side in the front and see if it makes a difference, you may end up removing two of the short ones each side or to get the flex you want, just don't go too soft as it can cause issues with diff wrap/rotation esp. under braking

Yeah I hear there is a bit of measuring and welding involved with it. My springs are from 4wdBits.

Thank you, I think it's a 6 leaf pack so 4 should be fine I'll give it a go. Can I leave the leafs on to take some out? I have no way of hoisting up my truck at the moment.

Sweet man I'll give her a try.


I don't want to have massive flex just to have a few inches more than what I have now.

Picture is about max flex there... The body angles too much for my liking I'd rather it sit straight and the axle articulate more.

my profile pic. is Rears up front, 4 leaf but old factory rears not new or HD.

Yup I found that I can get loads of downtravel have limted the up travel with extended bump stops so crossover steering doesnt hit the sump. Seems so work well are you running high steer?

You have to remove the leaf pack to remove a leaf its the easiest way only need a jack n some basic tools to do it.

That's pretty much the same flex I want on mine. Just enough and not too much.

Sweet. Gona have to get some of my gear back it seems!

I'm not running high steer which sucks! It's a bit expensive for me at the moment.. Which sucks because part of the steering arm has hit my drivers side front shock and put a small dent in it...And I wanted to get a cert.

So your still running your diff torque rod? This really limits your flex and is elemiated using high steer. Its needed when using the push pull j-arm steering under brakeing keeps diff from pulling to one side.

That is correct.

Tho I wouldn't recommend doing it, I took the torque rod off mine and it still behaved fine, tho being a truck driver I'm probably used to a bit of brake steer anyway

I can deal with that for better flex. What does a torque rod do anyway? What is the risk of not having one?

It stops your truck steering left (pretty sure it's left) under braking. Because the steering is push pull rather than side to side as the diff moves under braking it changes steering geometry. If you take it off your truck will no longer be warrantable and will be dangerous. In short don't do it unless your truck is low speed off road only.

If you can't afford crossover steering leave your suspension as is and fit lock right diff locks both one end or both. The only thing better than locked diffs is flex and locked diffs but not flex on its own

what you have to factor into it mate is the more offroad capable you make your truck the less onroad capable you make it its not hard to get your truck really offroad capable and end up with absolutely scary and dangerous body roll, torque steer, bump steer, death shakes, lack of braking from oversize tyres, lack of torque from oversize tyres, driveline vibrations from lifting etc to the extent you don't even want to drive your truck anymore coz it handles and drives like a dog on the road, eventually you learn the balance how far you can mod shit and still keep it an on the road compromise by all means experiment and learn by modding shit and get your truck going places but bare in mind what the onroad consequences are

Can second that, my old hilux when I first got it had the torque rod removed by the previous owner and by christ it could find the shoulder or the ditch beside the road damn quick under any half decent braking. In went hi steer pretty quick.

I guess I'll leave it i then haha. I understand the concept of the better offroad the worse on road. I'mm not going crazy with mods as I can't really afford it. I'd like lockers front and rear but I haven't even got my 4.88's in yet! LSD rear and plan to lock front. Sweet thanks for the info.

What's the go on inverted shocks? Worth it?
