Product Information

MSRP: $1,000,000.00
Average Price: $21,850.72
Manufacturer: JKS Engineering
Yes: 60 / No: 1

The B1 Body Lift by JKS offers an economical solution to tire clearance problems, without affecting center of gravity, spring rate or steering geometry like suspension modifications. Unlike universal designs commonly used by our competitors, JKS B1 Body Lifts are specifically designed to work in conjunction with the OE body mounts.
Our B1 Body Lifts actually provide 1.25" of additional tire clearance, as opposed to the standard 1" provided by other manufacturers. The Jeep® specialists at JKS have found this to provide the ideal amount of tire clearance without exceeding the safe working parameters for severe off-road use. Furthermore, no modifications are required to the fuel tank, air conditioning, radiator, or brakes, unlike taller body and suspension lifts.
Manufactured from premium Dura-Thane™ poly material with a hardness of 94 durometer, JKS B1 Body Lifts are designed to easily exceed the demands of four wheeling.

Pros: like how they fit over OEM mount-easy install
Cons: Grill support are a PITA, took as long as whole lift to install!
Recommended? Yes

Comments: Installed w/JKS MML--instructions said I did not need TC linkage bracket, but they were wrong. Could not get into 4Lo. Ended up with AA linkage bracket to divorce TC from body alltogether.

Price: $120.00
Pros: Easy to install with well written instructions.
Cons: Body bolt torque amounts a little too high.
Recommended? Yes

Comments: Installed with a JKS 1" MML. Very easy install. Recommended torque values a little too much (30-40 ft-lbs). I found 15-20 ft-lbs is best to keep the dreaded pop/clunk/rattle out of the picture.

Pros: Easy to install, Great instructions
Cons: None
Recommended? Yes

Comments: Installed in conjunction with a 1" MML. Went on easily. Did not run into any problem. Installed in about an hour and some change. The use of an impact gun helps alot. I loosened all bolts by hand then ran them off with a gun. Went very smooth.

Pros: 1.25" lift instead of the typical 1"
Cons: None
Recommended? Yes

Comments: Very easy install. As everyone else says, the radiator bump stops are a pain but freezing them before install helps as well as taking the headlight out and pulling with pliers.

Pros: 1.25" and ease of install.
Cons: None.
Recommended? Yes

Comments: I have owned and installed both this kit and the PA 1" kit (on my old YJ) and I prefer this kit. It gives the extra .25" over most others and the parts were great quality. Took less than an hour for the install.

Pros: Gets you 1.25" higher at the fenders and rockers.
Cons: None.
Recommended? Yes

Comments: I did a 1" MML when I did mine, so the install for the BL was less than an hour.

Even if you've never turned a wrench before.. this should still be an easy install.

Pros: Not a lot of parts to mess with. Pretty basic install.
Recommended? Yes

Comments: Great product...gives the perfect amount of lift without the hassle of messing with brake lines, fuel filler and so on. It really helped to hear what other people had to say about the install. The directions are fair, but the input that everyone on this site gives is EXTREMLEY helpful.

Pros: Easily installed, Good instructions.
Cons: None.
Recommended? Yes

Comments: Very happy with the JKS Body Lift. The Radiator Bump stops are a pain to install. Liquid soap helps. Also the body mounts nearest the rear tires are much more easily accessed with the rear tires removed from the axle.

Price: $85.00
Pros: Raises the body by 1.25", just as advertised.
Cons: none
Recommended? Yes

Comments: This is a great body lift. I have no comparison to others, but it has done exactly what I wanted. The only part I had trouble with on install was that I did not notice the differing lengths of bolts. I had the wrong length bolts in some of the holes and had to uninstall them. No trouble at all.

The quality of the components was excellent and I have no question of the safety of these parts.
