I have never been very happy with the way my truck flexs. The kid i bought it from installed a pro comp lift that is rock hard. It might as well be lifted with cinder blocks.

Anyways i had some first gen 2wd rears laying around.

Question: are these too soft to handle the weight of the sbc???

I know RUF are a popular swap/ but is 2wd ok?

here are some pictures of the new stance with 2wd rears.
i love shackle angle now!!!


still need new u-bolts, and a flat pitman arm, then i wanna try these babies out.

Plus i think i moved the axle forward an inch or so, and she doesn't look so tippy anymore!!!!!

Ron's 85

anybody have any input. 2wd rears too soft???

yoder519

im guessin sbc= shortblock chevy? i would say theyll be to soft. but thats just me. id say theyll flex like no other though haha

Ron's 85

yes i agree with your flexible answer. I was kinda hoping that somebody running RUF's would answer this question!!!!
i hope they are VERY flexy.

small block chevy yes!!!!

will i have too much negative travel???

i will keep you posted.

until then bring on the advice!!

looks good, you may want to add one more leaf just to make the pack last longer. but youw ill love these springs, yes they are super soft and flex great.

Ron's 85

thank you for the input 85toy. the truck i pulled them off of had 270 thow on the tach. you think they will settle more than they aready have??

anybody have a flat ifs pitman arm for sale in washington 360????

i hope when i remove the rear blocks she'll sit level until i
find a set of rears??

i think im gunna get some perches and try out the 63's!!!

how much up travel should i expect? im thinkin 2 inches or so to the bumpstops!!!!

does that sound about right?

Ron's 85

I got side tracked the last couple of days with these!!!

NEW! drilled/vented v6 rotors on hubs 25 bucks!!score

i am also collecting parts to finish this front suspension!!
anybody have a flat pitman for sale in washington!!!

plus i did a little camping/fishing with my boy and the old man up at Silver Lake.

85toy

they wont sag more with normal driving but if you wheel if hard they may break after awhile.

Ron's 85

BREAK!!!!!!

Hmm maybe i will add a leaf or two.

does anybody else have experience with these 2wd's????

i got the truck out and flip around start removing the rear blocks.

slow n steady

85toy

reason being that if there are too few leaves in the pack the axle will twist under heavy load, which is called axle wrap. and that can damage the leaf springs, but adding another leaf will make the pack stronger and less likely to twist.

Ron's 85

I AGREE. when i moved it around the garage a little today a noticed that it's REALLY soft up front. which is what i want!!

im waitin for my u-bolt flip to arrive. then i will decide after a few flex tests.

when i decide to add the leaf, where should i put it? i think i might be affraid to cut the centering pin on the pack due to previous nightmares!!!

i think i should put it on the bottom.

i was also wondering how much up travel most people have with this setup!!!!

it looks to me that i might have 2 inches or so, MAX!!

I've seen it done, throw an AAL in thier if they are too soft.. really though, the best way to tell is to drive it. just make sure if you leave it, get some sort of anti-wrap.. I like the shackle angle too..

Ron's 85

yotaman, when you say add a leaf, do you mean put the leaf on top too??? i hope to have it on the road this weekend if the new flip kit arrives!!!

When I built my ruf pack I used the top 3 main leafs from the rear pack and the lower 3 leafs from a 3" all pro front spring pack.

This picture shows the 2 rear main leafs and 4 lower all pro leafs. I ended up swapping the third leaf for a softer pack.



From the research I did on them, I figured using some new leafs mixed with old would give me a longer lasting pack. And I would run at least 5 leafs in the pack, if not 6. As my pack is now, it doesn't take much to go into negative arch. I will be installing bump stops this week, and wheeling it this weekend to see how everything performs.

Ron's 85

i did a few flex tests and YES it did go into negative arch fast.

tomorrow i am gunna pull the springs back out and rework them with a few of my old pro comp springs.

Hey E type R, i have been watchin your build!!! lookin good

LIVES4CRAWLIN91

why not add the second leaf out of the old pro comp frts into the ruf pack an see ifthat stiffens it up and also adds a lil more uptravel...

Lysmachia

If you end up buying an add-a-leaf, the vendors have instructions. I think WabFab and ToyTech both sell AAL's

Ron's 85

sorry i have been slow on the build lately i have been visiting family out of town. hopefully this week i will have a chance to redeem myself.

I probably will use a pro comp leaf. im cheap!
