Teraflex

looking either between

1. JK Wrangler 2.5" Performance Budget Boost w/shocks | TeraFlex Suspensions


2. 2.5" JK Lift Kit w/Shocks (2 dr) - Wrangler JK 07+ | TeraFlex Suspensions


first 2 differnces i saw was price for one. 2nd link is like 200 more but has shocks. first one is spacers.

which one would last langer? i like the 2nd one cause it had the coils.

My vote would be for the coils. Better long term solution IMO.

Either way can't go wrong with TF products!

Agree. BB will lift your Jeep for less, but the stock springs will sag over time and aren't very good to begin with. New springs will serve you better in the long run.

Check with vendors here on the forum...doubtful you'll find a better price, and often free shipping.

I have posted on this topic as well.. From the responses i received the one that made my decision for me was that someone mentioned the new springs will sag over time as well, just like the springs they replaced so you lose height with both lifts with time. But, new coils and shocks will help your jeeps performance instead of just making room.

That was the summary and I agree totally, BB lift is the cheap way for larger tires and that 'look', coils/shocks is the performance way.

I guess it depends on what your using the jeep for.

I went through this this past summer. I went with the coil spring lift with shocks. I figured either way I was removing the springs, so I might as well put new ones in. Good luck with your decision!

Get the teraflex leveling kit, it adds 2 in the front and 1 in the rear to give some added clearance and get rid of the stock rake on the vehicle. Cheap, too, especially for a DD. I went this route, have yet to pop it on yet, 33 inch DTs tires are on the way.

I got a metal bumper an winch and my front end sagged. I added the TF spring lift and the sag was gone. I've had it for 3 years and still no sag. YMMV

Yes, go with option 2. You will be happier in the long run. We had a guy call us yesterday. Just about 3 months ago, he did the BB on his wifes JKU. Then last month he added a bumper and winch. Now, he has the sag and the factory rack back. He is now shopping for a coil lift!

I also agree. Let us or any other vendor here help. We can usually offer you more than just looking around on the net. Feel free to PM, email, or call at any time!

I've had both TF BB and coil lift. Both BB and coil lifts from TF come in three varieties: 1)with shocks, 2)with shock extensions, and 3)no shocks. So there are really six options.

BB vs. Coil Lift
If you have, or are going to get, an aftermarket front bumper, you should go with the coil lift. With stock bumpers and no winch, the BB will provide a smoother (stock) ride. The TF front coils are stiffer than stock, so the coil lift with stock front bumper and no winch will give you a stiffer/bumpier ride, but after adding the aftermarket front bumper and winch, the ride smoothens out again.

Shocks vs. Shock Extensions vs. No Shocks
I was told by a Teraflex Rep that the shocks that come in the kit are comparable to the stock Rubicon shocks in quality and ride. The kit with shocks will give you an inch or so more downward travel. I would recommend this option for those with manual transmission or an aftermarket front driveshaft. If you have an automatic transmission and stock front driveshaft (like me), you might want the kit with the shock extensions instead, passing on the additional downward travel to avoid contact between your stock front driveshaft and tranny pan or tranny skid. Get the kit with no shocks if you want aftermarket shocks but don't want Teraflex's.

Durability
I would think that any of the above options would provide many years of service. I haven't heard anything that would indicate otherwise.

Other considerations
1. Wheel Spacers: If you're running stock wheels, you'll need 1.25" or 1.5" wheel spacers to avoid your rear tires from rubbing against the swaybar link bolt.
2. Control Arms: After adding the lift to my JK, I found the handling to be quite flighty/jumpy on bumpy roads and while braking. I added front lower control arms and increased my caster to about +5.5 degrees, and that fixed it. Others did not feel the need to add aftermarket control arms. Try it without aftermarket control arms first before buying them.
3. Trackbars: I didn't like the additional stress that the rear trackbar drop bracket put on the stock trackbar frame mount, so I eventually removed the drop bracket and replace the rear stock trackbar with an aftermarket adjustable one. I also replaced the front trackbar with an aftermarket adjustable one to recenter my front axle, but it was only a little bit off center, no big deal but if you want to do it right, the axle should be centered.
4. Coil retainers/Limiting Straps: If you go with aftermarket shocks (Teraflex or otherwise) which give you more downward travel, you may find the need for coil retainers or limiting straps to prevent your coils from popping out on full drop. Test it out after your coils settle. I've heard a few stories of coils popping out on the trail from too much downward travel.

Yes, that is my set up, no rubbing, and I haven't even trimmed my pich seam/rails yet. I think I may look into to some lightweight bumpers though. The other rigs seem to have gotten more lift than I did.

I vote neither.

I added bumpers and winch. Then the stiffest OE springs available from a JKU. Then the performance BB with shocks from TF.

It was okay...


The good:
The stiffer springs were the right spring rate; the 2.5" was the right height.

The bad:
No correction for the front trackbar --- the swaybar links looks like an unholy terror with their angle. No correction for caster --- the Jeep wandered all over the place and I had to add cambolts and tack-weld them in place.

The ugly:
The trackbar relocation mounting bolt sheared off on my first trail use with the lift. It stayed in place though, even stayed torqued. Took me quite a while to figure out why the handling was squirrelly.

The shocks they offer aren't bad but aren't all that super-duper. If I were to get another JK, it would be lifted with either a Rock Krawler 2.5" lift (and Bilsteins) or an AEV.

my tires are not 35s...they are 305/70/16 so that may be what you are seeing. I have some heavy bumpers too and am looking at the new RR light weight ones.

My tires are 315/75R16, basically 35's but probably measure just under and I have stock bumpers. Will probably add heavy ass XHD bumpers though. Oh and have an OR Fab tire carrier on the way.

Check out the new Rugged Ridge Light weight bumpers first. They look good and are lightweight.

The pics of your Jeep were the height I wanted out of the lift. I should have known better since I did the Unlimited Spring swap to get my Jeep looking less squished with the stock wheels/tires. I was contemplating switching bumpers or getting 3" coils, but I really rather not have to deal with the front bumpstops again. Actually I found the fronts the harder of the two to get installed.

so heres my plan please dont judge on any. its my jeep like what i like. sorry for coming out straight forward.

Lift -
2.5" JK Lift Kit w/Shocks (2 dr) - Wrangler JK 07+ | TeraFlex Suspensions
Rims -
20 inch black rims (havent decided which brand yet)
tires -
33's AT's

would the 33's look to small with the lift or should i go for 35's? heard if i go 35's then ill have to regear. could i manage 35's w/o regear? would it be okay for highway driving still? i usally drive a 1000 mile trip (500 miles to home then back) once a month but the my 2012 with the 3.6 and 3.21's have 275/75/R17 and measuremeant came out to like 32.16 tall size. so going to a 33 shouldnt affect anything beside like 1 or 2 mile off speedo? correct??

Thanks,

P.S. looking on Rough country at there XD Rockstars. 20 inch rims with +10 MM offset. if i ran the 33's and there 1.5 spacers. it shouldnt rub at full turn correct?

Why 20" wheels? The first time you do any serious offroading with those wheels and 33" tires, you will probably have some wheel damage. You won't have much sidewall to protect the wheels. If you don't plan on anything but dirt roads, you should be ok.

You probably won't need spacers with 10mm offset. I'm running 35" tires on 17" wheels with 12mm offset and I don't have any clearance issues.

x2 on the 20" rims.. You need to run bigger tires or you will be getting new rims. As a ball park a 20" rim needs around a 38-40" tire for proper sidewall spacing.
