Hey guys so im having some issues with the ride quality after installing a lift and tires/rims. The truck feels a little sketcky to drive on freeway after you hit 70, You feel a little bit of vibrating once ur goin 70+ before i got the tie rods replaced, the vibration was way worse and freeway driving felt sketchy. I got them replaced and it helped a ton but still past 70+ it vibrates a bit and doesnt feel dialed in. i cant tell if its the tires or if i have a suspension part worn out, everything looks solid under there And its been at two different shops recently and they said everything looks good. Alignment was done two days ago. Im starting to think that its because of my rear end setup which i think Is very stiff. I have the belltech Adjustable front shocks on stock springs and adjusted to 2 inches of lift, rear has the bilstein 5100 made to fit a tahoe i believe, (not 100% Positive if there for a TB or Tahoe,) ill have to double check, it also has the 2 in longer z71 springs in the rear and a 2 inch zone body lift all around, its on 16x8 method 702s with +30 of offset and 5.6 of backspacing, on 1 inch 6x5.5 adapters. There fit on 285/75/16 goodyear duratracs. The ride Just doesnt feel dialed in yet even though everything looks solid. Its got 65,000 miles and the owner was an older fellow that didnt drive it very much. so im thinking alota the suspension parts should still be in decent condition, Most of the stuff i think is still original besides front shocks,outer TREs, CV axles, and Rear shocks n springs. Ill double check what front end parts were replaced just to be sure. Ive read some other onwers that had z71 springs and HD bilstein shocks say that without the rear loaded with stuff the ride was very stiff, and with the truck loaded that it feels way better, i have nothing in the back besides a small subwoofer and a little bit of recovery gear but im just not sure if the rear setup thats whats affecting the ride quality on the freeway or not. Ill be providing some pictures of the suspension and so Any feedback would be great! Thanks guys. - Ben
