Hopefully the last Rock Krawler 3.5 XK thread we'll see

Well I was fortunate enough to have the lift donated by a friend that owns a parts company in the Cleveland area. I got up today and opened the box read over the directions and grabbed my tape measure.

Pic 1 and 2 are stock suspension. All pics of the vehicle on the ground are in the same postition and down after a 2 mile ride to load the suspension.







The first measurement from the ground is 32 inches.

now you'll see the vehicle lifted and disassembled. The next measurements cam from both the factory lower strut mount and the RK strut mount. There is a 1.5 inch difference.



That just mud and a slight bit of rust you see.

Simple hand tools are all that is really needed, but impacts sure do speed it up. Make sure you have a torque wrench ready. It's so easy my 14 year old son Tyler did the passenger side.

The rear poly spacers were a breeze to install, although the fronts were easy too. Anyone with simple hand tools, a floor jack and stands can do this in the driveway in 3-4 hours if you don't know how to work on vehicles. This complete job took me less than 1.5 hours after the stands were under it. Shot of the read.

Done and back on the ground the front netted a 2 5/8 inch actual increase. The rear was 2 inches. Job was easy. The ride hasn't changed and now there is plenty of room for my new tires and wheels. Those will be installed when the tires show up. 255/75-17 BFG Mud Terrains that are on closeout from DirectDiscountTire. I should have them by Wednesday.

I can't remember who wrote it, but in the last week on one of the other Rock Krawler threads someone suggested it was a combined number of front and rear. I was sure it was too. To add another 2 inches to the front would be too much front the UCA's to handle. The front is just 1.5 inches longer than the stock strut mount which translates to 2.5 overall lift in the front.

Personally I think they could have shortened the rear poly mount 1/2 inch and leveled the package out nicely.

Another change I would have made in their design would be to make the strut mount surface area longer and add two bolts on the pinch clamp. I think this would added support to the system for offroading. I wouldn't purposely and repeatedly get this system airborne for fear of failure in this area.
