Hi, brand new to the forum here. I got my 2019 Trail Boss earlier this month and have been absolutely loving it, been doing a bunch of mods to make it sort of my own. I put new tires (Falken Wildpeak At3w 295/70r18) and they rub a tiny bit but its not that big of a deal. At this point, the last thing on my list for this truck is to level it out, but I'm reading that the ReadyLift UCAs (their 1.75" kit) rub against 295/70r18 on stock wheels. I don't have the $ to buy new wheels with a more negative offset, so I was wondering if anyone here has had (and fixed) this issue. Theoretically if I just ran small spacers I should be able to clear the UCAs no problem right?

But, the OEM UCA are junk.   The angles with the level are in the "grey" area and your axels are not happy either (in my opinion) The TB angles are already in grey area.   (go look at them.   Not level).   You re adding another 1.75-2" of that angle and the ball joint is not happy either.   You will have it apart, just do the UCA at the same time.   don't pay for (2) alignments).  :)

Ok, thanks. I think I understand what you're saying. So the ReadyLift kit should be fine with my tires as long as I run a slight spacer to clear the new UCAs?

You can run spacers to solve the problem - pending how much space you need.

Careful with the spacers... unless you go over 2" you will beed to cut your studs.   Don't forget this step!

I just put a set on mine. Yokohama geolander x-at 295/70/18. Also have the RL level kit with new UCAs. They fit but it’s tight. No rubbing against the UCA. Not sure about rubbing the mud flaps I had already removed those.

This isn't universally true.  Many wheels will allow stud protrusion past the face of the spacer.  Mine do and I'm running 1-1/4" spacers and no trimming.

Awesome. Will likely order the kit soon. Worst case I have to go over to autozone and get a 1/4" spacer.

I’m running a 1-1/2” spacer and I got good clearance of the UCA. Stance looks 100% better and I’m still on stock TB DuraTracs for now.

The studs are not touching the back of the rim on your rig?   Are you sure?

This is what the rest of the world sees. (and what every reputable manufacturer tells you to cut the studs)

"The rest of the world sees"??  🤔

 

My studs stick out past the face of the spacer by about 3/8".  Luckily for me, the stock wheels have pockets between the lug holes that are plenty deep enough to accept that.  Too bad for the rest of the world.  😂

      MPG at 600 miles

      By Chuck FB · Posted

      I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality.

      We had two Toyota’s with that engine in the mid 80s. We had 50 gallon fuel tanks, a toolbox full of tools, an air compressor and assorted parts for our equipment. We beat those up and down pipeline ROWs until we started buying diesel trucks. Then they became parts runners and first vehicles for our teenagers first cars. Our shop Forman wrecked them both two years apart when we hired him out of high school as an apprentice. Good thing he’s an excellent mechanic. It took awhile before he could be called a good driver.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      I have a 2025 GMC Canyon Denali.   On a trip recently the engine failed.  The dealership diagnosed a bent valve and says there is a service bulletin that indicates to 'relace the engine'.  The truck only has about 14K miles and is under warranty.   The failure occurred 5/11/2026.   So far I have worked with GM Customer Assistance and Roadside Assistance.  Evidently no engines are available and nobody will offer a date when a new one will be.   Coming up on two months with no repair or timeline and no loaner from the dealership.   GMC Customer Assistance is 'ghosting' me and keeps closing the cases I've opened with no resolution.   Hoping someone can help me on how to escalate this issue.
