Price: $311.60
Pros: Nice road feel without excessive stiffness.
Cons: Exterior strut tube appears very slightly larger than OEM. Had to spread strut clevis mount very, very slightly to install the Bilstein 4600s. Dead blow mallet came in handy.
Recommended? Yes

Comments: Bilstein 4600 series are the actual items (not available in pull-down menu).

I purchased front and rear sets based on the vast majority of other comments as to the ride improvement. Reviews on other sites showed a very high satisfaction level--I agree.

Installation notes:
1. Great advice from JeepForum on how to install. See:

2. Exterior strut tube appears very slightly larger than OEM. Had to spread strut clevis mount very, very slightly to install the Bilstein 4600s. Dead blow mallet came in handy.

Comments: Bilstein 4600 series shocks/struts are what I installed.
Very nice improvement over 70k old OEM.
Not a major "wow" but they made my Jeep feel new again.

Install note for front struts: Exterior strut tube appears very slightly larger than OEM. Had to spread strut clevis mount very, very slightly (with screwdriver) to install the struts. Dead blow mallet came in handy.

Price: $300.00
Pros: Firmer ride, but not uncomfortably so, and reduced roll.
Cons: None evident so far.
Recommended? Yes

Comments: Not cheap, but definitely a big improvement in ride, quality and longevity over stock shocks. I expect to get 10 years/100,000 miles or more out of these shocks. Only nit: it's nearly impossible to slide the rubber bellows covering the shock rod down to eliminate bunching of the bellows in collapsed position.

Price: $292.00
Pros: Good control, look nice, 2" longer than stock
Cons: A bit stiff, more expensive than most shocks
Recommended? Yes

Comments: I recently installed my Bilstein HDs, and haven't even taken them off road yet. On road the handling is noticeably better, and I am looking forward to adding 2" to my Jeep now that I have the option.

Price: $70.99
Pros: Made by Bilstein... What else do you need to know?
Cons: Move along, nothing to see here
Recommended? Yes

Comments: I replaced shotso KYB rear shocks with Bilsteins. Although my Upper Rear Control Arm bushings are almost non-existent, it is hard to tell the difference. But the difference is still there. I'm wondering what kind of Coil Springs to install now. Tomorrow is install day for the rear upper and lower control arms and ball joint so I will have a 100% better understanding of the difference. Stock crappy 9/16" sway bar but I did chrow on some Energy Suspension poly bushings. Even that made a difference but next for the rear will be an Addco 1" Sway Bar and maybe Eibach Lowering Springs (message me and let me know what you think of those springs - I'm not into lifting it higher or off-roading. I want a little lower center of gravity). Same goes for the front. Soon. Hopefully.

Price: $260.00
Pros: Controlled ride, great quality, stiffer than stock but in a good way
Cons: None really
Recommended? Yes

Comments: My WJ feels a lot more controlled over bumps and imperfections in the road. The ride and handling difference between the Bilsteins and stock are night and day. The ride is a bit more firm, but in a positive way. Takes bumps like a champ on the highway too. Highly recommended!

Pros: Great shocks for the money
Cons: None really. Why buy anything else?
Recommended? Yes

Comments: Purchased from Summit Racing after having them price match, got them literally 25 hours later. Installation was pretty straightforward. One of the best shocks you can get for your money.

Price: $250.00
Pros: Excellent handling and very responsive.
Cons: Can be stiff for people ( not this guy though). Also not direct bolt on. Metal sleeve needs to be ground a little to fit.
Recommended? Yes

Comments: Amazing shocks. Handle great on the road and offer an excellent ride. You can feel the bumps alittle more with the stiffness of the shocks. But the zj feels safer now. Not like a brick on jello

Price: $4.00
Pros: Excellent ride quality
Cons: Spendy to buy new, only good for stock height.
Recommended? Yes

Comments: Got these for dirt cheap at a junkyard, and they are so very much nicer than the rock hard Mountain Ryder IIs they replaced. The softness means a little more body roll in the corners, but who drives a Jeep fast anyhow?

Price: $260.00
Pros: Much firmer ride More control No more "floating" after bumps
Cons: The ride is a little more harsh
Recommended? Yes

Comments: Great upgrade from OEM shocks/struts after lift. Even before putting on lift my WK was floating after hitting bumps above 45mph. This got a little scarry during rain storms. While putting on my RC lift I noticed some serious rust damage on my OEM strut and put the money in a new set of Bilsteins. The ride since then is so much better. The WK holds the road over bumps, does 10x better off-road, and the only downside is you feel the road a bit more on the highway (not much more) but certainly worth the trade off.

Pros: Smooth even when mudding, excellent handling
Cons: Can't say there are any.
Recommended? Yes

Comments: The shocks are very tight, nothing sloppy on street corners or mud ruts. You're still in touch with the ride, just a bit more comfy.

Price: $260.00
Pros: Noticeably smoother & quieter over the Gabriel shocks that were on the TJ when I bought it.
Cons: None yet
Recommended? Yes

Comments: My '98 TJ now has 138K on it and has a stock suspension. When I bought the Jeep 9 months ago, it had some old Gabriel shocks on it. They looked ancient and very rusty. I didn't think that my Jeep drove the way it should. I decided to treat myself to some new shocks and bought the Bilstein HDs after reading the positive reviews here.

The Bilsteins turned my Jeep into a much smoother riding and stable vehicle. The road noise and rattles are much lower, too. I am very impressed.
