The Big Brown Truck of Happiness delivered the H&R Sport Springs (P/N 52107) yesterday. Today I got a chance to unpack them and give them a once over.

They sure don't look like they are progressive rate springs. The coils are evenly spaced and the wire diameter is uniform end to end. Good thing I didn't have my heart set on these being progressive rate springs. The paperwork that came with them says I'll get 1" lift front and 1" lift rear. That remains to be seen after install, of course. The interwebs says anywhere from 3/4" to 1 1/2" of lift. I'm really light, so I'm betting on this being closer to the 1 1/2" lift of things.

The springs themselves came packaged in a really nice box, inside another box that was strapped, and included sales literature and a bunch of stickers. No installation instructions, which wouldn't be especially useful anyway. The springs are heavily powder coated, and look to be of very good quality. Nicely finished ends and that sort of attention to detail that makes one think of a quality manufacturing process.

@AOR gave me a great deal on a set of Bilstein 5100's to go with these springs, so when they get here the whole mess is getting put on the Jeep. Got all the tools, nuts, bolts, misc. parts and help rounded up for the install. The fasteners of interest for the install have been regularly sprayed down with PB Blaster for the last week and a half. It should go as smoothly as TJ suspension work usually goes when the time comes.

You're 100% certain they are progressive rate springs? For some reason I didn't think anyone made those for the TJ.
 
I'm 99.9% sure they aren't progressive rate springs. H&R is known for making some really good progressive rate springs, but these aren't one of them. It was noted on other sites that they are, but I was skeptical. If they are, it's some magic with the heat treatment and temper, because I put calipers to them and they are pretty uniform in wire diameter and coil spacing end to end.
 
Did they sell them to you advertised as progressive rate?

I believe Currie and Savvy springs are progressive rate.
 
Nope, the only mention of progressive rate springs was in the H&R general engineering notes for all of their springs and in the generic sales literature on line. They have a good site by the way; the tech articles are pretty informative on the materials they use and their manufacturing process. The product description on the H&R site for these specific springs didn't mention the spring rate or "progressive rate" one way or another.
 
Got it. Yes, I've used H&R springs on every European vehicle I've ever owned from my M5 to my M3. They make great suspension components, no doubt.
 
I remember you telling us that. We'll see how they do with TJ suspension components. I've read all over the place that these springs paired with the Bilstein 5100's make for a great combination. Other shock combinations, not so much. I think that @Ahoragi is running these springs on his TJ, but don't remember what shocks he paired them with. It will be interesting to compare notes.

Just so this doesn't get lost and for future reference: Running light, my TJ weighs in at 3,300# and loaded out it comes in at 4,100#.

Running light, the clearance from the flat part of front control arm frame bracket is 11 3/8" L&R. The rear is 11" on the L and 11 1/4" on the R to the bottom of the rear lower control arm frame bracket.

I always ran my H&R springs with Bilstein shocks, and it was the nicest ride ever. If you look any almost any European car forum, the general consensus is that the Bilstein / H&R combo is the best ride you can get for the money.

Of course those are European cars, so I'm not sure how they'll be on the TJ, but my guess is they'll be great. I run the Bilstein 5100 shocks and absolutely love them.
 
I have no worries on the road because of the stellar reputation of that combination. It's at 25 mph and below with high articulation that has me a little worried. I spend a lot of time in that speed and road surface range, and it remains to be seen what these things do in that situation. Just as a guess, and from what others have said, it should be fine as well. I've got a couple of "roads" in mind to give them a good thrashing out. A nice combination of washboard, potholes and other surface imperfections. There's one section of an old skid trail that they put piles of dirt all over awhile back to keep people out of the area. When they went to open the road back up, they just knocked the high spots down a bit and left a really ugly section of road about 150 yards long. It'll be a good test for going slow over big bumps. You can twist the crap out of your suspension with no effort involved at all. Lots of second growth trees to winch off of too.

Curious how these springs and shocks combo has done for you? How the ride quality, how much change in height did you get, and would you do it again or recommend something else?

I still like this combination a lot. The ride is firm and controlled, without being harsh or jittery. On washboard roads you'll need to air down and disconnect...or drive faster than is probably advisable.

I got right at 1-1/2" of lift with these on my light SE.

I'd buy them again, and recommend them to anyone with a TJ and tired stock springs. Especially if they aren't looking for a lift.

Hope that helps.

Awesome. I don't need any significant lift for my kind of wheeling, just something to offset the extra weight of my skids. Wife and kid still need to be able to get in and out, and I hate doing engine work on lifted rigs. Thanks!

Where is the best place to purchase these springs and the shocks ?
