2015 Yukon XL Fox vs OEM ride quality?

[Mondaytown]

I'm still a noob on suspension but I worked in transmissions for years, the number one thing I told customers is to add an aftermarket cooler if you're planning on doing any towing at all. They aren't very expensive and they'll pay for themselves many times over in the long run.

Yes the tranny was blown when I bought it. Definitely a weak point. I put in a circle d stage 3 billet trans with a plus 500 stall billet. Running the Mishimoto radiator and trans cooler with the thermo delete.
