H&R springs 52107 vs 52109 on TJ

Hi guy's and gal's,

I'm new to coil sprung jeeps but have had 7 or 8 jeep cj's and yj's previously. I'm wanting to lift a 2000 tj sport short wheel base (not unlimited) with a front bumper, maybe a winch, spare, rear seat, and hard top with H&R springs for a lady friend. H&R spec's the 52107 for this application, and show approximately 1" of lift, they spec the 52109 for the unlimited, with approximately 1.5" lift. I have read much of what is online, in the forum, and even called H&R without coming up with an answer as to what I would get if I put the 52109 on this TJ. H&R couldn't or wouldn't give me any information on the specs other than the amount of lift, and they couldn't or wouldn't tell me what configuration the test vehicle was 4 or 6 cyl, hard top or not, etc... They would only say they spec each number for a generic specific vehicle. They really weren't much help. So, has anyone used the 52109 on a tj that is not an unlimited? If so, what did you end up with in lift, handling, and ride quality? I'm asking because I'd like just a little more lift than the 1" of the 52107's. Any feedback is appreciated.


Here is a photo from the forum showing the difference between stock, 52107 and 52109 springs. Note, photo may not show due to my post count.

Hmmm had no idea they were different. Been looking for a pair of rears only for my jeep and can't find any ugh. Will be keeping up with this though.

Have you read this thread.

https://www.jeepforum.com/forum/f9/1-...-lift-1150250/

Edit, I would venture to say the reason H&R won't tell you what you want to hear, is that these spring are actually a lowering spring for a totally different application.

I am multi-talented, I can talk and piss you off at the same time.

Yes, I have, it was a good read. Thank you though. The only things I have found are TJ's using 52107, and LJ's using 52109's. I'm wanting to see about using the 52109's on a TJ.

Glad to see these pictures of the coils. I'm wondering if the LJ rear coils will keep the factory rake that my TJ would have had. I'm not terribly heavy but there is an add-a-trunk, the soft top, and a hard top in the rear. I'd prefer not to lose the factory rake.

The company has a design philosophy that won't work if you put their LJ springs on a TJ, so don't be upset that they haven't invested the time in trying it, because they have a sizeable product line-up, and I doubt they're making enough sales to be inefficient.

Somewhere in here is a thread with a TJ at about 3" - 4" of lift using the H&R rear LJ springs. He liked it a lot, but it will take some searching to find it, because this forum's been looking like a ghost town lately.

It may be worth the search to find what he used up front. If you use all 4 LJ springs on a TJ, you may be the first person to report the results, but deviating from intended use sometimes requires experimentation.

I say all this because my first improvised lift kit for my TJ was mis-matched. However, I hit a home run on my second try, so I've always felt it was worth the risk to experiment. I also had this experience with my Trailblazer, of getting it right on the second try.

Oh damn that's more lift with the rear LJ springs on a TJ than I was expecting.

Yes, some of the LJ owners noted the H&R springs gave them more rear lift than they were expecting (and most of them liked it), but of course it will be even greater on a TJ, but a significant lift on a TJ will be complicated because of the usual reasons (e.g., the TJ's shorter wheelbase, etc.)

Maybe the numbers of views of other threads like this one will allow H&R to see there's interest in their products in the Jeep community, so maybe going forward they'll invest a little bit of time in R&D for new Jeep products ?

That sure would be nice. The reason I like the H&R springs is because it doesn't provide a radical lift which is something I don't really want. I'm running 31s which is all that my usage requires. Stock/close to stock is all I'm going for while potentially improving the ride which some seem to have said that the H&Rs provide.

Yes, I think there are a lot of people who just want a spring upgrade instead of a radical lift. I've upgraded the springs on all of my vehicles, but I wouldn't want to lift higher, not even on the Wranglers.

At a minimum, H&R's dual-rate approach will improve your sway control, so H&R's TJ springs on the short wheelbase will be a noticeable improvement. Somewhere in here there's a monster thread with numerous testimonials.

The most off-roading my Jeep sees is beach work down here on the South Texas coast so there's literally no need for additional height. Stock articulation suffices as well. The 31s are nice from an aesthetic stand point. Anything beyond that is simply unnecessary. If I went any bigger, I'd have to start looking at a regear which is not something I'd care to do with on the D35 so I'd be looking at new axles and it'll quick devolve down the rabbit hole of supporting mods lol.

I've gone through some of that mega-thread I believe. Still haven't decided which way I want to go for shocks...Rancho, Bilstein, or Fox.

A fairly new development is the Rancho RS5000X. It gets a lot of good reviews, but most of the H&R threads' posts pre-date the 5000X. As a result, those older H&R posts mostly talk about Bilstein and OME.

I've read a bit about those and it seems to be what's in flavor combined with the H&Rs. I forget about the OMEs...that would be an interesting choice as well.
