Bolt on SOA kit?

[mancheman86]

Ive done some research and for my needs a bolt on Soa kit would be alot easier for me, I'm having a really hard time tracking one down. does anybody have a link or a suggestion other that a welded kit i could do? if i do this bolt on kit i will be able to drive to my work (far away) and weld the bolted on perches. don't have a welder or anyone to weld it close to where i live (out in the boonies)

put a XJ rear end...

You still have to move the perches. 

 

Learn to weld.

While I don't fully recommend it, many people have put the perches on without welding and then driven to where they could be welded.

 

Personally I'd just do some math and have them welded on ahead of time. If you're going with a big lift you normally need to do an axle upgrade anyways, might as well get two birds stoned at the same time.

that won't work

Rocky road outfitters used to sell a bolt on soa kit. No welding needed.  

I know people love to bash on RRO. But I have bought some stuff from them and didn't have any problems and I got quality products.  I have had their control arm drop kit on my XJ for like 7-8 years.  No problems. Works great.  Better design then Rough Country or Rubicon Express.

Here is a link. You have to scroll through some text and pictures.  But you can buy the bolt on soa by itself.   

If I soa my 88 this is the route I would go. I have a MJ AMC 20 under it and I don't want to move the existing perches.

What axle are you running currently? If you're going through the process of SOA, might be a good time to swap in a better rear end like a 29 spline 8.25 or a 8.8. Another plus is you could have it built and swap it over without the issue of not having welded perches. It might be tough to set your pinon angle though. 

 

I'd go with ruffstuff. This is a u bolt eliminator don't have to go this fancy but it's everything wrapped in one package, minus shock mounts.

I ordered the Rocky road kit, thanks for the advice guys I'll keep ya posted on how it goes

I ran the RRO kit on my MJ for years, originally it was bolt on with the factory D35 and later i welded the kit to an MJ D44.

It's sitting under my sons MJ now, I wouldn't buy the kit again but it worked well for me.

 

I will say that i have seen the RRO kit fail though,it got loose on a YJ D35 with stamped perches and twisted back and forth until it eventually pulled an axle tube out of the housing.

 

The cast factory perches would hold the SOA perches in place much better but either way keep a close eye on them or just weld them in place.

I'm curious about the bolt ons too. I was going to go quick and painless on my lwb 86 2.5 2wd for a quick lift in rear since I have multiple spare xj lifts for front. I also plan on complete gut and swap down the road with a 44 rear. When I called around 2 months ago, the guy on phone told me they were the same kit sold for lwb swb 4wd or 2wd. I asked how it could be the same with different drive shaft lengths concerned on the pinion angle. His answer was that's a good question I don't know and I needed to call back the following day to talk with another guy. Meanwhile the kits are a pay and wait deal. So I passed it didn't sound quick or painless.

 

Without a SYE, the pinion angle does not change when you go SOA.  The same kit would work in all cases.

 

With a SYE (specifically with the double cardan driveshaft, that's actually the deciding factor) it matters that the pinion be pointed 2 degrees above or below the output on the tcase (with below being favoured unless you're running an antiwrap bar, basically forget I said above as an option since we're better off not discussing that), and there is still some leeway there (if it's within 0-3 degrees it will probably be fine), which given the generally long driveshafts of the MJ you're probably going to be close enough.

 

That said, I still think the kit would be an abomination, and I almost always recommend a SYE and the double cardan driveshaft to go with a bigger lift like a SOA.  That's my opinion, not interested in discussing the SYE or not thing.
