Review on ๐Ÿ”ง Upgrade Your Wrangler JK Suspension: American Automotive 3" Front + 2.5" Rear Steel Coil Spacers + Shock Extenders - Leveling Kit for 2WD and 4WD by Joseph Elvis

Revainrating 4 out of 5

The kit is inexpensive but you will need additional parts.

I installed this set of spacers 2.5" front and 2.5" rear on a 2016 JK 2 door. The parts in the kit were good quality but if I were to do it again I would replace the hardware with better nuts, bolts and washers. The instructions are a bit easy, but there is a process on YouTube. One bad omission of the kit is that there are no spacers for the bolts holding the front shock extensions to the bottom flange where the shock was mounted - I had to make them out of tubular steel. You won't get any significant torque without clamping this flange, so these washers are a must. I installed the kit myself and had no other issues but my mechanical skills are high. My total setup time was 12 1/2 hours including collecting my bikes from around town, washing them, prepping the hubs and installing the wheel spacers so maybe 4 hours was spent on things other than the lift and an hour was spent spent to find out what a shock absorber seal is and how to use brake line extensions. I also took my time, walked lightly and slowly, and didn't use power tools. Here is my general opinion. The kit is nice and inexpensive, but you will have 5 issues to contend with. First, both axes are off-center. For the rear you need a bracket to move the steering rack. For the front you need an adjustable crossbar. Without them, the geometry won't be correct, despite what other reviews say. For front you will need longer anti-roll bar end links, order a kit for rear and install them on the front. The steering wheel is off-center and requires a traction adjustment. The instructions show the wrong adjustment point, you are adjusting the tie rod, not the tie rod. Finally, the caster is too large and the road holding is very unstable due to the angles of the front arms. This can be perfectly corrected with the help of front wishbone mounts. In my opinion, there's no way you can just put this kit in, go, and have a well-driving jeep. However, once I've added and completed all these other elements, it's great. The hardest part is making the spacers for the rear springs. Fill the base with foam so you can push the bolt up and attach the nut to the wrench so you can position and hold it in place. It should be firm, don't stop until it is. If you lose that screw you could bend to the point of losing the gasket and then you would be in trouble. Finally, the front brake line extensions should extend the lower brake line bracket, not the upper bracket attached to the frame. I don't know why this isn't in the instructions, and you should also unplug the wiring from the rear calipers. There's a lot of extra wire in there, and it can be lengthened by simply cutting off one of the clips.

Pros
  • Very good price
Cons
  • Unbelievable price
