H&R Spring Review

[JustSumDad]

The spring is physically longer with additional coils though, so without a longer bump stop it could bottom out, as the H&R lift is quite small I don't know if this would be a problem, the OP on this post had issues, but Erskine didn't so difficult to call, personally I'd go with Tom's rule of inch of lift = inch of extra bump stop for peace of mind.

ok, I figure the rear adding a hocky puck to the bottom of each side is minimal. Not sure how they secure, but I will work that out when I see the setup first hand...
how are front bump stops done?

This is what the extended front bump stops look like - you can get these ones on eBay or if you call Terraflex they apparently still sell theirs but just don't have them online. they just snap into a cup on the body above the upper control arm.

I have tried several times, and I still can't get mine into their home. The day I get them in ill celebrate. All the difficult things I do on cars and can't get these in

A great member from here sent them up to me from their place.

They appear to be for 2" lift. do you just cut them down to match a lower lift?

A 2x4 on edge using the tire as a fulcrum seems to work for most.

found another reason to use longer bump stops, tire size considerations.
Even if your setup cannot bind the springs and the shocks are protected via stock bump stops as mine are.
larger tires may still rub in full flex and this can be mitigated with a bump stop extension.

The tires on our rig are 245/65R17 and we have not found any rub, tho I have yet to flex it fully out (two corners off the ground and wheels cranked over)
I might add 1" bump stop to the rear as we do the springs, front bump stops are in very good condition and like I said, unless the tires rub, nothing to worry about.
IF they do rub in the future we can do the fronts then.

I contacted H&R tech and asked about the springs compressed length, it is equal to the stock spring so bind is not an issue.

You could probably cut a bit off, don't know how easy they are to cut though.

Can't hurt to give it a go. At least I know once it goes, it won't be coming out...... ever.

Using the 5100s with any type of stronger springs is ill advised
SITTING SOMEONE UP WITH A BAD PROBLEM

Anyone thinking or wanting to use the Bilstein 5100 adjustable front shocks , think again
If you do want to use them, not sure why but,.....
You should not install them any more than sitting at the 0 mark, that is it
Any higher and it will create a disaster , degrading the springs within a few months
It preloads the springs which is very bad much like cheap spacer lifts do
These shocks should of never been built in the first place
4600s are cheaper , are the same internally , and are built for the KJs/KKs to keep the same spring perch at stock distances
Jeepinjarhead and I have discussed this and just today I seen a discussion suggesting someone use them
Please do not , unless you want to spend the extra money , set them at 0 just to say you have them

Hi Tommudd
Our original 06 kj renegade 350k+ miles.
I had auto repair shop swapped to 4600 shocks w original coils back at 140k At 240k I had to replaced front suspension stock parts new struts as well . so it's still a daily driver ... I now have bought 5100 with no coils and read your 2011-2021 posts recommend
For stock ride height 925/947 or 926/947.
I run 235/70/16R . My current ride height
Measured is 17.5" in front and 18" in rear.
I'm sagging... so is there a coil at 350lbf that will put me back to stock as the 925 or 926 coil and 947 /948 in rear? We're in our 60's now and keeping the kj up to ramble about in SoCal desert area cities. Not looking for lifting but reliance. We did really like the stance change the kj had with the 4600 on but we could not go too much off-roading in washes due to front fender tire rubbing at times with the 235. Hence 925 or 926 coil is great as long as I don't have to modify due to new installed lift height.
Thank you for consideration and your time.
