Only problem is that the all pro springs are shorter, and with that, you get about a 90° shackle angle. that angle transmits ALOT more bumps and jolts into the truck than a shackle that is laid back some. Also when the shackle is laid back, it allows more droop, and the spring has more leverage on the shackle, thus a better ride. But i am sure you already knew that.Chrisf said:the 44044's and the allpro are the same spring rate I would think that they would ride similar
You need to look at eye to eye length not the over all length of the spring. over all length follows the arch of the spring, not the location of the shackle. the 44044's have more arch than the allpros would be my guess.... we need on of the allpro team to respond to this and answer all the questionsHick said:I dont flame, i give direction.
Stock length springs are 45"
44044's are 47"
all pros are 46.5-stock length, 47.5 long travel (mount moved 1.5" forward)
You can run long travel springs in the stock location, just need to watch the position of the center pin. the APOR hanger moves the axle forward, and only .5" down (.25" lift). So drop is neglegable.
that said, i still think i want to run 4" long travel springs in the stock location, unless i start running into firewall clearence problems.
your right. Also i want to know why all pro seems to like to design the springs so the shackle is at 90°.Chrisf said:

Yes, you can run the 44044's with a drop hanger (i would not recommend this due to too much lift) or you can run them in the stock front hanger with some minor trimming of the spring bushing. I recommend a 2 1/2" rear shackle in the stock postion (Performance Products make a really nice bent style for about $40.00, I highly recommend them.) If you use 44044's with the drop you will get 5" of lift plus the amount of the dropped hanger. 44044's in the stock postion with a 2 1/2" rear shackle nets you about 5 1/2" of lift on a 85 w/ 22r this is PLENTY for 35's with no trimming at all. You can do 37's with some minor trimming. You also have to weld a spacer on the drivers side spring perch (85 yota axle) in order to level out the ride. I used a 3/8' plate that did the trick perfect.Can you run the 44044s with a drop hanger similar to APs and longer shackles in the stock shackle position or is it better to mover the shackle position. This is on an 85. I keep hearing all different things. One moment I got is figured out then I hear other.
I've asked this question numerous times and Chris G. always seems to "run-and-hide" instead of giving an answer. If a longer leaf spring will flex better, then why not make the springs long enough to at least give some shackle angle...wouldn't that also improve flex? I have seen Chris post that Jon Bundrant(owner of AP) prefers a 90* shackle angle front and rear, so that's what they "recomend". When I ordered my rear springs from AP I asked Chris a couple times if I HAD to move the rear shackle hanger back to get the springs to work, and he said it HAS to be moved back. Well, we didn't move it and I got a perfect 40* shackle angle.Hick said:

Same setup here. I removed my bottom leaf. Might remove another this time aroundBen Holloway said:i run 44044s with one leaf gone, i love them, ive got it setup so my uptravel aint much but they sure droop nicely
