moving spring hangers for better shackle angle

Just wonderig if i was to cut the rear spring hangers for the front springs in my zook and weld them back on 25mm forward. Would this create the same thing as a half ruff as its a nt i cant just redrill the hangers and it will look more stock and create the better shackel angle and wheel base extension am i right ?

and also i can still use front springs

could i aalso do this in the rear?

thanks in advance for any info

cheers jesse

It will help a bit but you wont get the big advantage of added flex by using the longer rear springs

ok so it will be more of a ride improvement?

Better ride, a bit of extra flex from the shackle angle and better hill climbing and decending due to wheel base.

If you are going to all that hassle is it possible to move them back an inch and fit rears ?

yeah but i thought rather than buy new springs and pull them apart to make them softer just use fronts do rear spring give extra lift as im running 2'' lift will i need 2'' lifted rears for the front?

For all the work, you won't get enough gain.

You could get the same effect by redrilling the spring pads to bring the axle forward 1" and cutting the front shackle hanger off and moving it back 1" That's easier because the shackle hanger is welded to the bottom of the chassis only, where as the spring hanger is welded to the bottom and inner side of the chassis.

Personally, I don't think you're going to see enough benefit to make this worthwhile. You're also going to create a monster because when you get sick of the crap ride and short travel of fronts you'll have to undo the work to put rears in it.

Rears do provide more lift - they have more arch in them, but they also have a lower rate os the spring sits deeper into it's travel at ride height. That's where most of the better ride comes from.

ok i read a thread in sierra bible. It said the you cant redrill the spring hangers in a n/t as they were smaller than the w/t hangers, is this true? i will use the rears up front i have a standard height set i found

Yes it's true, that's why it's in the bible ;)

On average the rears give you about 1 to 1.5 inches of lift depending on the shackle you use.

Zookster, i did this mod when i went RUF.

I did it this way as i didnt want to do a chassis extention simply because of the front bar set up/powersteering etc.

Its a pain to cut the rear mount of, as Steve said, its welded to the bottom and inside chassis rail and can be quite dangerous as you need to cut near fuel lines. There is also a chance that you will weld it on unparrallel to the other side, which will have dramatic effects on handling.
It would be better to make up a plate to go either side of your standard mounts, and weld/ bolt that on, then redrill back however much.

Finally, no point doing this with standard front springs, get rears.

ok first of all thanks for the help and info i will go that way around and make some plates drilled further back and weld them on my shackles are 115 mm center to center

cheers jesse

done this on mine also.

didnt get the whole RUF gain but a big difference to std front springs.

I also used a spring relocation aka RRO kit and i am looking at longer springs one day too
