running a shi**y aftermarket “lift” consisting of (we’ll assume) CNC machined blocks of AL - top it off by running tire/wheel setup that is way off what was originally designed for the Raptor, & throw the air pressure all over the place- dart on wall, & having issues w/ ride quality & wobbling @ hwy speeds isn’t surprising really. You’ve also compressed the stock springs up front altering the geometry & rebound etc from what was designed from the factory.
aftermarket wheels- even pricey ones- are almost always a tier below OEM when it comes to consistency/quality- who knows if the wheels are actually all exactly the same size/offset/weight?
I concur w/ other- road force balancing, torquing lugnuts to proper spec, getting alignment done, but ya F’d w/ the suspension geometry on a truck that quite literally has the most R&D on its suspension in the history of pickup trucks. Good luck I guess?
I used to get run a winter tire setup on my old G8 GT & the rims I had seemed to always accumulate solid chunks of slush/ice on the barrels, this would always result in my car vibrating/shaking like it was about to come apart until the stuff fell off or I got out & wacked it off w/ something
at any rate, having wheels unevenly balanced or tires out of round can have extremely noticeable effects on ride quality, & those effects are compounded as both speeds increase & the well as the weight per corner....& sounds like in most cases here ALOT more weight is being added per corner on a vehicle that ALREADY has some of the heaviest running gear on the road
