RK vs Clayton - most opinions wanted

I havent seen Joe around for a while, so I'm going to throw this out to the masses for some help. I am getting very close to getting a suspension lift for the new heep. The two I am currently debating are 1. RockKrawler JK 3.5 X FACTOR PLUS MID ARM SYSTEM and 2. Clayton Off Road Mfg. JK 3.5 (Full Traction is a possible 3rd). Since I am still a complete newb to suspensions, what puts one of these over the other? RK is cheaper & has shock relocation brackets, but I do not know if new shocks are required. CORM sells Bilstein 5100s for another $320. CORM is completely bolt-on, which means I could do all of the work myself. I do not know if RK is bolt-on or if welding is required. What else would I need with either of these kits?

1. RockKrawler JK 3.5 X FACTOR PLUS MID ARM SYSTEM
$1699.00 from Absolute Offroad
  • high clearance - high misalignment lower control arms front and rear,
  • high misalignment front upper adjustable control arms,
  • front sway bar disconnects,
  • and long travel stainless steel brake lines.
  • independent three link rear conversion with adjustable anti-squat geometry.
  • The rear axle on the 3.5” X Factor Plus Mid Arm System is moved back 1” to allow for greater clearance between the tire and the factory rock slider
  • rear shock relocation brackets that move the rear shock mounting position up 2 inches for better ground clearance under the lower control arm mounts on the axle.




2. Clayton Off Road Mfg. JK 3.5
$1,899.00 from Clayton Offroad Mfg.
  • 3.5 - Front coil springs (pair)
  • 3.5 - Rear coil springs (pair)
  • JKS swaybar disconnects
  • Rear swaybar extensions
  • Front set of brakelines
  • Rear set of brakelines
  • Front Adjustable trackbar with misalignment spacers
  • Rear trackbar bracket
  • Front bumpstop with allenhead bolt (pair)
  • Rear bumpstop with 2 allenhead bolts with nuts (pair)
  • Front lower double bent adjustable control arms (pair)
  • Front upper adjustable control arms (pair)
  • Rear upper adjustable round bent arms (pair)
  • Rear lower adjustable arms (pair)



OR should I ditch both of these and get the Full Traction 3" Ultimate kit for $1774.95... which includes:
  • 8 adjustable upper & lower control arms for both front and rear,
  • heavy duty adjustable front & rear track bars,
  • new generation front sway bar disconnects,
  • rear links,
  • bump stops,
  • off-set brakeline relocation brackets, and
  • ride frequency tuned coil springs for a comfortable ride

I can't tell from that picture and I couldn't find it on their website but does the Clayton kit use Johnny Joints?

I would have to call to verify.. I know I read from them they "Used a rubber bushing frame side, and a heim joint axle side" but I believe that was regarding a ?trackbar? I saw on their FAQ for other kits that JJs can be rebuilt, so that would lead me to believe they use them.

Are Johnny Joints good or bad?

BTW... feel free to vote based on the reputation of the company or on the parts you see here. I know you guys are not running these set-ups on JKs. Just let me know what you vote & why, please.

I just called Clayton's.. they do use Johnny Joints on flex points and a clevite bushing on the axle ends. The rear uppers have JJs on both ends. The front uppers have a 2" JJ built in-house (not Curries).

Full Traction uses "4130 Cromoly Heim Joints" and is fully bolt-on.

I do not know what RK uses for joints. I also learned the RK needs welding of the Rear Cradle, Rear Third Link Mount and Rear Shock Relocation Brackets

You are exactly right. There is some cutting and welding involved in the RK 3.5 Independent 3 link rear. You have to weld in the cradle and the upper control arm cross member, and you also have to cut your rear shock mounts and weld on the new RK ones that are higher up. It's a bad ass setup and you would love it on your JK. If you aren't into the fab part then you can also use the standard RK 3.5 setup that uses upper/lower CA's in the rear.

Personally I don't like what Clayton's setup does with the rear trac bar. To me it looks like they are dropping the mount on the axle end like a TJ needs. The JK's are the exact opposite. The bracket needs to be weld on and at the axle end to move the trac bar mount up. RK has re-engineered this to be stronger. There are a lot of busted trac-bar brackets that show up at the shop.

Joe has been having issues with his site and this site on his laptop. We are also right in the middle of moving his shop to a bigger 5k square foot shop.

EDIT: yes I have personally seen the setups you have mentioned. RK is still the best you can buy.

I have seen the RK kits and I know they work and work well. The others I have no experience with. I have installed a couple RK kits also the welding is very limited and the kit is well thought out.

Jack, Joe or Hackle, do you have any pics of the RK kit installed on a 4-door Rubi? Side shots, front, underneath, flexing, etc?

I dont have any of the above lifts, but a friend of mine had the Clayton 5.5 LA installed at their shop, and I was beyond impressed with it. If I only had the big $$$ to get one. Someday....
