I placed an order for the BakFlip MX4 for the Carbon Pro on December 9. Initially they gave me a 12/31 delivery date. Then they revised to a 1/31 delivery date. Last week, they gave me a 3/4 delivery date.
Also @rikhek - I was going to go with the Ridge Grappler in a 285/70r18. Smaller tire (34") but little wider at 11.5". Curious how much clearance you have between tire sidewall and stock UCA with those 285/75s? Extra 1/4" width on my tire means (theoretically) I would have 1/8" less clearance from sidewall to UCA on my anticipated setup of 285/70s. Thanks man.
@rikhek - any other pictures from front/rear with that level and tire setup?
I was thinking of going with the Zone Offroad 1.75 kit. (https://zoneoffroad.com/products/175-in-leveling-kit-2019-2020-chevy-silverado-trail-boss-gmc-sierra-at4?variant=33477556338776) They claim to have maintained factory steering geometry and specifically not affecting the ball joints / UCAs by putting them in a severe bind by changing the angles too drastically.
