Outer Limits 4x4 Board

i was wondering if anyone had a good site or info on leaf spring length/width im chasing a set of longer springs for me 47series ute ive read on ebay of a bloke puttin 60 series into a 40 are they a good option for the extra length im chasin?? ive already got extended shackles and i just need the longer spring to get me a better shackle angle
thanks for any info

check out the cruiser bible you will find heaps of useful info in there.. specifically 60 springs in a 40.

The ironman website has all their spring specs on it. It's a good reference.

ok sweet i had a look at that ironman webbi and i think i got a option i might be able to go with,
goin by the number only really checked the length and centre bolt positition

rear 60 series on the front of me 47 (might have to thin the pack out a bit)which give aprox 100mm extra length and bring the front diff forward about 50mm (not sure if this is a good thing or not tbh)

and 79tray back rears on the back of the 47(thining again mayhaps) which are about 170mm longer and move me diff back about 40mm

now i havnt actually looked at the pin size or spring width so after i do that, ill probably be back to square one and because the front gets moved forward it will have to wait till i can do the ps conversion to boot oh and ill need to organise drive shaft spaces to :( ill probably be broke or to old to drive the ute by the time im finished the way this is goin heheheh
