  1. Your stock wheels are +24 offset, these are -18. That's a total difference of 42mm (1.65" outboard), Yes, your larger tires will rub and you'll have to trim the back of the fender liner. I have a 3.75" lift and my 285-65-20's rubbed badly with a -44 offset. Pretty major trimming of fender liner.
  2. These are BORA spacers 1.75". The tires poke about 1" on stock 20's. Quite a bit of fender liner trimming. If you go with a smaller spacer, you'll have to cut the factory studs in order for the wheels to fit flush against the spacers.
  3. Yes. I like that sound. I have Goodyear Wrangler Ultraterrains. Too quiet. I don't like overbearing loud exhaust but tire noise, yes. I know. Weird.
  4. 2021 Sierra AT4, ReadyLift 1.75 Level Kit, 285-65-20 Goodyear Wrangler Ultraterrains (34.6 tall 11.2 wide) 1.5" BORA spacers, minor plastic trimming. Sittin' perfect.
  5. First Mod, filled up the wheel wells. 285-65-20 Goodyear Wrangler Ultraterrain (34.6" tall x 11.2" wide) ReadyLift 1.75" Level Kit (includes UCA's)
  6. I went with the ReadyLift 1.75" front level with top and bottom spacers and new UCA's. A couple comments on this kit. If you are going with stock tire size/Stock wheels, you're fine. Any tire size larger that 275 wide with stock wheels will rub on the ReadyLift UCA's. The new ball joints are HUGE. So I had to use spacers to push the wheels out to clear the UCA's. Not really a huge problem, but the entire purpose of doing a lift/level is to put on bigger tires. A 275mm tire is NOT a bigger tire. ReadyLift needs to address this so this kit will work for 35x12.50's. Other than that rant, I like the kit. Nice, smooth ride. The perfect level for me. (1/2 inch lower in front, which is what I wanted), Reasonably priced. My tires are 285/65/20's Goodyear Wrangler Ultraterrain. (34.6" tall x 11.2" wide) Love the tires and the level look.
  7. I also totally disagree with the engineer that there is no excess wear and tear on the lifters and pushrods! What a crock! All in the name of ONE mile per gallon. One word. Pulsar LT.
  8. Yes, November ? 2020 through March ?, 2021. There is a topic on this forum specifically about the defective lifter issue. A GM tech who works at the engine plant stated that engines built before and after those dates have the "good" lifters and lifter springs and should be fine. But I still disabled DFM anyway with the Pulsar LT, even though my engine was built way after the defective date. DFM causes way too much wear and tear on the lifters and pushrods with the constant activate/deactivating! V8 all the time is the way to go. Be sure to remove the device prior to any dealer service appointment. Only takes a couple minutes to install/uninstall. Here's the link to the defective Lifter thread... Lifter issue: TSB PIP5776E - published June 18 - 2019-2021 Engine, Driveline, & Exhaust - GM-Trucks.com
  9. I just installed the Pulsar LT on my 2021 Sierra AT4 6.2. Five minutes to install the hardware. 10 minutes to program. Very easy. Speedo calibration for bigger tires worked perfectly when checked against GPS on Google maps. My truck doesn't have Auto/Stop so I cant speak to that. But the DFM is NOW DISABLED. I have a Borla exhaust and I could always tell when it kicked into "chopper" mode. Now V8 all the time. Pricey, yes. Worth every penny.
  10. '21 AT4, 6.2L, 285/65/20's (34.75"x11.25") No level, No rub. VERY minor trimming of passenger side mud flap. (Utility knife cut off about 1/4" of plastic) Solid rear glass!
  11. After searching for a year I found my truck. Wow. Love this thing. Just upgraded to 35's.
  12. Filled out the wheelwells a little today. Stock tires were GY Wrangler Territory 265/60/20, new rubbers are GY Wrangler Ultraterrain (10 ply) 285/65/20. 34.8" tall... pretty close to 35's. I had to do a little minor surgery only on the passenger side mud flap. Driver's side cleared by 1/4". Just had to trim a little off the passenger side with a utility knife. Pretty easy. Stock wheels, no level, no spacers. AT4 stock suspension. Balanced out perfectly. Discount tire... highly recommended. See before/after pic.
