Posted: Tue Feb 07, 2006 22:31 Post subject: DIY Suspension Lifting - The How to |
|
|
I know this guide has been a long time coming, for which I can only apologise, but I hope it will motivate some of you into lifting your Troopers. This guide covers suspension lifting for ALL Troopers / Bighorns, and indeed any other Isuzu based 4x4 (yes, even Fronteras )
At the time of writing, my 3.0DT Trooper was riding at +65mm (2.5"), all of which is covered in this article. It has now been lifted to +90mm (3.5"), which is a bit more complicated to say the least, and at present there are still some more mods I need to do to regain some lost downward travel. I know what is needed, and once it has been achieved successfully I shall write about it and let you all know how it's done.
For now though this should get you thinking ;
http://www.itocuk.co.uk/docs/trooper_susp_lift.doc
It CAN be done, and if you know your way around a toolbox it's actually fairly straightforward, if maybe a little time consuming. _________________

Can't understand why shackles 3" longer than stock will only give 1.5" lift ? Please explain. _________________ Wine is fine, whiskey's quicker.

Simple lever principle. The axle is approx half way along the leaf spring. If one end of the spring stays in its original position ( the front ), and the other end is 3" further away from the chassis, then the axle will be half that amount, i.e. 1.5" further away from the chassis. _________________

Hope you dont mind me posting this here (if you do im sure someone will remove it)
It shows what can be done if you have a bit of imagination, one Frontera with a live front axle:
Cheers

Soooo, Mark, don't leave us swinging, details required, how & with what, ie what front axle was used, diff ratios etc etc. If its not yours, then your mission, should you choose to accept it.......

Hi Steve,
Yes this is my old beast, and some of the details can be found here: http://www.muddy-fronteras.co.uk/Axle%20Conversion.htm
It now looks like this sitting on its 33x12.5 grizzley claws just waiting to get a gearbox and have a 3.2V6 Isuzu lump in!
Cheers

Thanks for that Mark, nice looking truck. Glad you're paying for the petrol when you get it in, still with a smaller lighter body & manual g/box it will be a lot less thirsty than the same in a Trooper/Bighorn. Like you, I've mused about an solid front axle setup for the same reasons. I don't really need one (whats need ever had to do with a grand plan though , ) & her in doors ain't going to let me have one (on our current wagon anyhow ) but I reckon that a Range Rover front end or early Prado ( The Land Cruiser looking ones with the rectangular head light) would be a good donor. I'd want to keep it coil sprung to go with the excellent back end setup, & obviously keep the same diff ratio, possibly need custom R & P. (Ouch, expense wise)
Like you, I've seen some write ups from the US & keep adding to the info filed in the back of my mind.
Cheers, Steve. _________________ 95 Bighorn Fieldstar LS 3.1 TD |

No problem Steve,
the original lump was a very thirsty 2.4, im hoping that the more powerfull 3.2 will not be as bad with less weight to move.
The only reason i used the leafs and not the coils is because the rear was leafs to start with.
the truck now stands at 10 inch over stock and the live axle has transformed its off road abilitys!
looking forward to getting the 3.2 in and going out to play in the mud!
cheers

Word of warning - if doing the ball joint flip, do it before winding up the tortion bars !! Learnt this one the hard way. Undid the balljoint and couldn't get the lower wishbone to move to get it back together. I had to unwind the tortion bars with a jack under the wishbone to get it back together, then lift back up again.
If you've done the tortion bar windup - you'll know that's a lot of cranking with a breaker bar _________________ For great insurance deals on 4x4s, imports and more, contact Adrian Flux :

What is the ratio, roughly, turns per inch? _________________

We cranked mine about 12 - 15 X 1/2 turns for 25mm. It actually moves quite dramatically! _________________ 1999 Cougar with a NICE motor..

Normally about 4 full turns to the inch, maybe more depending on the bars themselves. _________________ |

That would be about right..difficult to judge if you can't get a complete 1/2 swing as in my case (the kerb got in the way!) _________________ 1999 Cougar with a NICE motor..
