Jeep CJ7 Springs Install ~ Superlift 4” Lift ~ Ep. 89

On my 1984 CJ7, I get rid of my Rough Country springs and replace them with a Superlift 4” lift with Rock Jock shackles. Step-by-step installation by JeepCare in Huntington Beach, CA.

Own an amazing old CJ?! Would you like to share it on my channel and you live in the Southern California area? Post a comment and we'll see if we can arrange a video walk around of your Jeep.

Got a cj7 in Camarillo!

[@tcsadventures]

@@paulreyes9752 What year’s your CJ? How long have you had it? Stock or modifications?

[@JoelFJB]

Thanks for the content and its awesome how you put the part in and numbers, great job man

[@tcsadventures]

I try to make the videos as instructive and helpful as possible - so it’s nice to get some positive feedback. Thanks!

[@JoelFJB]

@@tcsadventures yeah man it is greatly appreciated!

[@9greatdanes981]

I was happy with the factory spring. I wasn’t happy with any of the lift kits I’ve gotten, but I need them. I will move the steering box forward, add a Dropped Pin arm, wrangler spring conversion, forward shackle conversion. I will change it to a spring over, extend wheel base a little

[@tcsadventures]

Good luck with your project!

[@tonib9703]

Great video, Intellitronix makes a direct fit LED gauge cluster for the CJ

[@tcsadventures]

Thanks! They look nice, but I’m going to stick with the old school original dash. I’m trying to keep the body as original as I can. Appreciate the comment!

[@CJ-rk5eg]

You’ll have to do a follow up video to review the ride with the new springs. Thanks!

[@tcsadventures]

Definitely! I’m trying to keep from having too high of expectations - lol! But I do think it will make a big difference off-road. It does ride better on the street. These springs are probably a true 4” lift. The Rough Country was at least 5”. So I’m not riding quite as high. Thanks for watching!

[@CJ-rk5eg]

@@tcsadventures That’s a pretty tall lift for CJ, raising the center of gravity and increasing roll risk. Trade offs happen with every choice. Looking forward to seeing the next CJ video.

[@CJ-rk5eg]

@@tcsadventures how are the new springs working out, both on and off road?

[@tcsadventures]

I haven’t taken it off-road yet, but there is an improvement in the ride on the road. The new springs are less stiff and it’s less jarring when you go over a bump. I’m also riding an inch plus lower with the new lift.

[@Peedee1942]

Beautiful jeep

[@tcsadventures]

Thanks!

[@trellaford]

Hi There - Very nice CJ7. Do you know what your castor angle is? The new springs/shackles would have changed your castor angle with the different ride height.

[@fernandoelizondoortiz4655]

Nice looking jeep, congrats. I always thought the shackles where supposed to be at a 45º angle to get a smoother ride. I'm currently looking for a solution to it. Any thoughts?

[@tcsadventures]

I have no complaints about the way my CJ drives now. Superlift was a big improvement over the Rough Country springs. As to the shackle angle, I left that to Dustin. He works almost exclusively on Jeeps so he’s the expert. I can tell you that when I do the work myself (more on my sailboat diesel and outboard than my Jeeps) I almost always talk to tech support. I would rather get the manufacturers advice than opinions on line. Whichever shackle you go with you can call tech support and usually get great advice. In terms of an update, after the new lift, shackles, and steering upgrades - the jeep rides and handles much better. I had really bad bump steer before the upgrades and the RC springs were so stiff it felt like riding in a covered wagon (or at least what I imagine a covered wagon felt like). Thanks for watching and commenting!

[@shivadelon2306]

Nice bro 👌👌👌👌♥️♥️

[@barbarosariogul433]

is this the correct way to mounth the shock ? shock boot up ? or down ?

[@mikecostello9671]

What size tires are you running I like the look. Nice rig, learning a lot. Thanks!

[@tcsadventures]

They’re 33” on the stock wheels. I have a video on the channel where I do a walk around if you haven’t seen it. Thanks for watching!

[@gravesgarage]

Cool!

[@TheSuperduke08]

Thanks for posting this subbed you

[@miniken1]

What type of thread lock is that? I’ve never seen a product that gets applied after bolts are installed.

[@tcsadventures]

@@miniken1 I could be wrong (I usually am), but I think he’s using it to see if the nut loosens later. I have a friend who owns another Jeep shop and he puts a thin paint mark line across the bolt and nut during installation of parts. It makes later inspection easy to see if a nut is backing off the bolt (if the line on the nut and bolt are no longer in line). I think he’s doing the same thing with the thread lock. I suppose to, it could be of some help in keeping a nut from loosening. I don’t know the brand of thread lock he was using. I’m sure someone will let me know if they think I’m wrong.

[@KevinPlemons64]

What would you guess the proper amount of torque applied to the shackle bolts would be? 20lb-ft, 30lb-ft, more, less. I rarely do suspension work and usually just tighten until I think it "feels right"

[@tcsadventures]

I don’t know the answer to your question for stock shackles. Below is info Currie put out and I think my RockJock shackles are by Currie. Below that is a link to a Jeep forum where they’re discussing shackle torque. Hope that helps! 76-86 Jeep CJ and Scrambler - Shackle Install Instructions Assemble shackles onto the Jeep with the grease fittings toward the outside, and the lock nuts on the inside. Tighten the center brace first to 85 ft. lbs., then torque the shackle bolts to 16 ft. lbs. Do not over tighten the shackle bolts! Check torque on the shackle bolts after 100 miles, and re-check periodically after that. Grease with multi- purpose chassis grease or moly lube. If you have any questions during the installation of this product please contact our technical department at [phone].

[@gregorycary9982]

I also own a 84 CJ7. I was wondering if you are still liking your 4 inch lift. Any driveline issues. thanks

[@tcsadventures]

Yes it’s a huge improvement. Drives a lot better on the street and I haven’t had any issues with the lift.

[@tcsadventures]

I should also mention that the factory front drive shaft was replaced years ago when I put the Rough Country lift on. The RC lifted the Jeep 5” and the original front drive shaft wasn’t long enough.

[@229saint]

Hi, I have the same set up. Rough Country 4 "lift. Very stiff. I'm looking at upgrading springs, shocks and possibly shackles. Would you do the Superlift 4" again after having ridden on them for a month or so?

[@tcsadventures]

I would say yes it’s been worth it. I don’t know about your 4” RC, but mine gave me a lift of over 5” so my ride height is lower with the Superlift and I’ve had to get used to the different look. This Summer I plan to get it out more off-road and I’ll do a video update. I still use the Rubicon for long trips… we just got back from Death Valley. Thanks for watching!

[@micahgray1]

How does your jeep drive going down the road? I have an 86 and have a wandering problem with bump steer! I really wish I could solve the issue.

[@tcsadventures]

In episode 79 I get new steering components and it made a big difference with bump steer. The Superlift springs were an improvement too. Much less stiff than the Rough Country and less jarring when you go over bumps.

Where are you located guys? I need to fix my 1980 jeep cj7 I am in New York’ city

Southern California… a long way away!

[@chadneedham4211]

Do you have a list of all the components you installed on the Jeep suspension?

[@tcsadventures]

No list, but there are inserts in the video with all the information for the springs and shackles.

[@chadneedham4211]

@@tcsadventures ok have you upgraded the axels?

[@chadneedham4211]

What bilstein shock are you running?

[@tcsadventures]

They are 5100 series: www.amazon.com/gp/aw/d/B01BPKFERC/ref=ppx_yo_mob_b_inactive_ship_o0_img?ie=UTF8&psc=1

[@tcsadventures]

The axles are stocks. But upgraded differentials. Detroit locker in front and Truetrac in the rear. You might be interested in Episode 20 where I do a walk around of the CJ and talk about what’s original and what’s been upgraded. (shot before the springs and steering upgrades). Thanks for watching!

[@carmelomorasca3321]

Are the springs softer ?

[@tcsadventures]

They’re a lot softer.

[@Table1000]

do you want to sell the rough country springs

[@tcsadventures]

I left them with the shop and they got rid of them as scrap.
