The Ultimate Jeep Wrangler Lift Kit Comparison – Install & Measurements

Recently, I was able to spend some time with the crew at Dixie 4-Wheel Drive in Moab, Utah, where we had a very unique opportunity—take six, bone-stock Jeep Wrangler Rubicons, six different manufacturer's lift kits, a whole lot of 37-inch tires, and install them to see how they would perform. This was such a cool experience and whole lot of fun, and I don't think anything like this has ever been done before. 

I get asked all the time, “what’s the best lift kit for my Jeep?” The truth is, there is no right answer to that. Everybody has a unique need for how they use their vehicle. Maybe your Jeep is a daily-driver and you occasionally take it out on the weekends. Or maybe it's a hardcore rock-crawler and a dedicated weekends-only vehicle. It could be you enjoy hitting easy trails. 

Other considerations include budget and whether you plan on doing the install yourself or you plan on paying someone else to do it. Honestly, there are a lot of factors that go into deciding on what the best lift kit is. Hopefully, by learning what I thought about these six different lift kits, you’ll be able to make an informed decision about the lift kit that's right for you.

I will say that choosing a lift kit from a reputable manufacturer known for making quality Jeep products is very important.

And now, on to the comparison!

To make sure the focus was truly on these six unique lift kits, the crew at Dixie 4-Wheel Drive equipped each Jeep the same 37-inch tires. I want to emphasize that this was not an apples-to-apples comparison—these lift kits differed from one another in more ways than one, including their height, price, and ease (or lack thereof) of installation. 

Some of the lift kits were 2", while others were 2.5", 3", and some even 4". Some of them were quick and easy to install, while some will end up being a little more complicated. Some were reasonably priced and others, not so much. But all of these factors were an important part of this comparison because what you want your Jeep to be capable of and what your budget is for making that happen is going to be different, sometime very different, from someone else. 

Now, let’s take a look at the six lift kits we installed. 

Rock Krawler 3.5” X-Factor “No Limits” Mid Arm System (Retail: $3876)

This system is an impressive bolt-on, comprehensive suspension kit that includes triple-rate coil springs, front and rear 2.25 RRD spec shocks, all new adjustable upper and lower front and rear control arms, front and rear adjustable track bars—to help ensure you can keep your axle centered—sway bar links, spring correction pads, a track bar relocation bracket, and bump stops. 

This kit was designed for Rubicon owners who want maximum articulation from a mid-arm lift with excellent highway ride and improved off-road ability. No hard copy instructions were provided in this box, but there was a card with a QR code to download the instructions. The online instructions were solid—they provided some nice details with good color pictures. 

The install was easy work for the Dixie team, but if someone was to do this kit in their own garage, it would probably take them two or three days—the better part of a long weekend—because it is such a comprehensive kit. 

The manufacturer provided solid information about the required measurements of all the adjustable components, which was great. One unique thing about the Rock Krawler kit is that it is recommended you drill a hole on top of both front control arm brackets so you can face the Zerk fitting upward and make it easier to service. We used a plasma cutter, but a simple metal hole saw would work just fine.

According to Bryce at Dixie 4-Wheel Drive, it's better to have the Zerk fitting pointed up instead of down so they don't hit a rock and get damaged. In this case, Rock Krawler calls for a hole saw cut out to clear their jam nut and Zerk fitting. We measured to see how far down the shock fully extended. Structurally speaking, it remained solid after we made the cut-out, which was important since these Jeeps were going to be used pretty hard.
