RE 1.5 SOA - five leaf or six leaf to start?

I am replacing sagging wrangler springs this weekend on my 1987 Wrangler with an existing SOA lift, and I have four six leaf 1.5 inch SOA rubicon express springs. In addition to replacing the springs, I need to correct a 4 degree pinion angle with a 4 degree shim (I already have a SLE) to get rid of driveline vibrations that occur at exactly 60 mph. My current perches are about 1.5 inches high, and I bought new perches that are about 3/4 inches high - to help reduce any additional lift from the new springs that might aggravate the pinion angle. I have a full size 35 inch tire on the back, big rhino bumper with winch on the front, hard top, and 4.0 I6. If anything, this Jeep will only get heavier with the things I am doing to it.

On one hand... five springs seems smart to avoid aggravating the pinion angle issue. On the other hand... six springs seems smart due to the weight of the vehicle. What do you guys think? (I plan to start with six all the way around and hope the shorter perches will minimize the lift change).

I first ran the 5 packs on the front & 6 packs on the rear (HPD30/Ford 8.8).

Eventually I removed the bottom leaf from the rear 6 packs to make them 5 packs, so they are all 5 packs now, but the spring clips are in different locations. I did so to help lower/level the ride out a little.

I have a bunch of heavy stuff up front and out back and this combo works well.

Like you mentioned, starting out with all 6 packs may work out well for you.

My current set-up is with a HPD60 where the perch shoulder is ~1/2" tall. For the rear 14B FF, I used Rock Tactics perches which are ~1/4" shoulder height.

Sounds like everyone plays around with five and six. Ill start with six all the way around with the shorter perches and see how it goes.

I ran the 6 leaf packs in front for the last 2 years in my YJ. I always figured I'd run them like that and see how they broke in, then remove a leaf if I wanted to soften/lower the front. I was too lazy to ever actually remove the packs to do that so they stayed 6leaf until I bent one of the main leaves and RE sent me a new spring. While I was rebuilding the bent spring I removed the 2nd from the bottom leaf in each pack so I'm finally running 5 leaf packs. I haven't had the Jeep out since I did that but I'm sure it will be fine.

To my understanding the 5-6 aren't any different other than the extra leaf intended for anti-wrap which of coarse is for rear . When doing my lift I assumed the 6 was intended for the front due to the weight of the engine so I called RE and asked . They told me it didn't really matter because I had an anti-wrap bar anyway . My jeep sat that way for a few days until I switched it to the intended setup , no difference in stance . It was just a piece of mind move . Couldn't be happier with the spring btw.

Thanks guys for chiming in.

I do have an anti wrap bar... so I guess fives all the way around would be the intended setup.

It might come down to a six pack and a coin toss. Maybe, I have just read too much.

I looked at it like this. It's simple to make a 6 leaf pack a 5 leaf. Making a 5 into a 6, not so much. I think you'll be fine either way.

Did you notice any difference going from 6 to 5?

I haven't taken the jeep out since I changed it. Just did that a couple weeks ago after Dixie Run when I bent a spring.

and quite flexy, too, I might add.

He seems to be slowing... I suspect it is his age catching up with him... so I'll whore a pic in his stead...

Yep, they are similar, but not the same.

The spring clips are in different locations along the length of the leafs, and the leafs (beside the main leaf) are different lengths.

Hey Randy, yeah, I'm slowing.
