Post subject:  Suspension set up with 32' tyre for Sierra

hey guys, just after some opinions, I also want to see what has worked for others.
I have a set of 32inch 10.5 tyres going on f100 rims.

What type of lift have others used to fit these tyres and have them flexing. I know theres plenty of suspension talk. not much on this though.

Most people will fit that on a sierra with a 2" suspension lift and a 2" body lift and bump stop extension. If you are confident with a grinder and welder you could do a ruf and cut your guards and adjust your bump stops to suit.

Have a look in the rigs section there is heaps of info in there.....

2 inch suspension lift exstened shackles ruf and some cutting of the gaurds and some bump stop extensions should be fine when I get mine on I can show what I've done if you want

Guard cutting, bumpstop spacing, body lift fits tyres. Suspension is a separate concern.

ive got 2 inch body and no bumpstop spacing cos im a lazy fuck and they only rub at full lock a little bit. not enough to worry me but haha. also youll have to cut off your outriggers if you havent already worked that out

Tyre clearance and suspension are like peas and carrots, good together as Forrest says but are two totally separate things

I think i will start with the body lift as suggested with shackles. I guess theres only one way to find out and fit the tyres, see where it rubs and go from there.

Glad to know a body and shackle lift will be enough.

As a general, would a longer leaf spring say 2inch lift be better then a body lift?
Eventhough, body blocks seem to be the way to go.

Happy to trim gaurds, not too keen on cuttig off the outriggers. Is this a common thing for lifted sierra's??

It is impossible to run 32's without cutting the outriggers off. They will have to go.

You have no reason to use extended shackles. With otherwise stock/bolt on suspension, there is no gain to be had from them, only disadvantages, especially when used in the front, where the reduced caster messes with the handling and the increased leverage makes the steering less precise and slower.

Extended shackles might be useful as part of RUF or to trim rear ride height, but they do nothing effective unless they are combined with other (fabrication-heavy) modifications such as relocated chassis mounts, extended shock mounts etc.

Remember too that extended shackles only increase tyre clearance "static" - flex the suspension or bounce the car and the tyre ends up exactly where it would have with stock shackles. That's why I say body lift, bumpstop spacing or guard trimming are the only ways to fit bigger tyres, not suspension lift or longer shackles.
