hi, installed my lift on monday got wheels and tires installed today. i havnt put a lot of miles on it yet about 50 monday and 75 today. the lift went on pretty easy doing everything by myself took about 6 hours. All the parts were heavy duty all there brackets are much beefier than stock and they all made the stock brackets alot stronger i was more than pleased with the kit. Me and my family were pleasantly suprised on how good the ride was it soaked up the pot holes and didnt shimmy around the wash board corners. This morning i carried it and had my wheels and tires installed i ordered 5 15x10" wheels and took those with me and bought the tires locally for the free rotations didnt noticed till i got there they sent 4 15x10" wheels and 1 15x8" wheel so i went ahead and had the 4 installed. i used the procal to center the steering wheel, adjust tire pressure to 20lbs and to change tire size for the speedometer. i am very pleased with my lift and tires all the 35x12.50-15 tires balanced with 3 ounces or less weight. I had the little 225x16" tires ran about 2700 rpm at 70 now with 35's i run about 2200rpm at 70. i reset the mpg on the dash wich was pretty accurate always within 1/2mph of hand calculation. so far after 75 miles it shows i lost about 1/2 mpg on just normal everyday driving we will see in a week or so how the hand calculations come out.

 

another shot.

 

Looks good. I started with the series 2 lift and still have parts of it on my jeep now. Great lift for the money.

 

Same lift and love it. Got a little shimmy. Can't tell if its tires or not. Only through steering wheel, can't feel it in seats

 

Could be your tires. The only thing I did to my lift was add adjustable lowers. Made a huge difference in how it drove.
