so i was looking at the axle and leafs and if i dont move the leafs back on the main leaf my axle will
tilt down and mess up my drive shaft angle so i gotta drill a new hole in the top leaf and move the rest back. i hope it works i'm scared the top leaf might break at the old hole.

For the cost of a set of springs, are you willing to risk that?

yeah.... this is what i am kind of thinking all along here as well....

the whole "rear up front" spring thing happened a lot more when a decent spring pack was still 400 bucks or people couldnt get what they wanted as far as custom length or lift.
everyone now makes an affordable spring pack and it almost doesnt make any sense to putting the effort into trying to make rear springs work out front.

as well, unless you have healthy rear springs, you are only getting a few inches (3 max) out of a spring pack to put them up front and then you still have to cut and remount perches to make this work anyways.. or for it to work right..

spend the 300 bucks and order from marlin or even trail garbage and get yourself something better to start out with..

i know i should just buy a lift kit they are cheap but so am i.. lol.. i'm just doing this for now really just for something to do. i plan on getting a kit when i have the money this truck is off road only and i don't plan on driving it on the street after the lift is on new or not. the truck will not pass safty for the new sgi laws that will be coming anyways. i just like to work on things and try things out . and as for lift i got 5 inches in the front by useing the rears up front i have had the axle mounted just nothing lined up.

so i took the leafs to get drilled today at frame and wheel in regina. so now i need some ideas on how i should lift the rear. i was thinking 2" blocks and 2" shackels. i want to get as much flex out of the rear as i can. would i get more flex if i just use 4" shackels or 4" blocks? or would it not make a differance?

2inch longer shackles wont give u 2inch of lift cuz ur shackle sits an angle...

id say 2inch blocks would be fine.

ur not going to get it to match the front with out huge shackles or big blocks with stock springs...

u could get some f-150 springs... they should get u the right mount of lift with good flex.... u run them long side forward so u only need to front hangers...

i built hybrid springs for the rear of my truck.... they are 89 rears 51inches, with 2 old ford springs of an 70s, f-250 i believe... they ride ruff but still flex... out flex my 10inch shocks no problem.

4.5" blocks are a bad idea. I even think any type of block is bad. If you have put your rears up front may be check into installing 63" chevy's in the rear. You can buy the new mounts and the used leafs for probably what a set of blocks would cost you. Plus your front end would flex real nice with the rears up front. If you put the blocks on the rear it would only flex as good as a stock truck. Kind of defeats the purpose of the front swap.
Or lifted springs. They aren't that expensive anymore.

A shackle also only moves down half (the back half) of the spring. IE the spring hanger side stays at the same height, and the shackle side moves down 2" (actually the length of the shackle * cosine of the shackle angle, as you mentioned) so the centre of the spring, the axle, only moves down half as much.

So if you want an actual 2" out of a 2" shackle you'd have to move the hanger down 2" as well. (and have a 90 degree shackle angle)

You build them. Its pretty easy once you find the right size square or rectangle tubing. I used 4" -1/4" wall and drilled my spring holes and cut one face out of the tube. Then I sloped one end it at and angle so it would not hang up as badly and welded it to the underside of the frame

Stop by my place one evening. I have F150 rears under my 4runner but I mounted them short side foreward for my application. They flex really well from what I have seen so far and you can get a set at bucks for $40 but you have to pull them yourself which takes all of 20 minutes if you have a sawzall or a grinder with a zip disc. You just cut the u bolts off (which are under a lot of tension so be careful) then cut through the hanger's at each end.
