It's downright rediculous. Even with 8" off-road jack extension from my UTV it still barely lifts it enough to put 37's on, I had maybe 1/2" between my garage floor.
I think the reason this is the 37pp has a slightly different spring perch than the 35 trucks, it's thicker providing around 1/4" more lift due to slight increase in preload. I would bet that's why most 37pp only see around 1" of lift and the 35 trucks closer to 1.5".
Almost certain there aren't any differences around clutches and/or shift points, PN are same for each trans. It's possible the shift tables that are adaptive might be different but that is something you can reset in Forscan to some capacity as I have done that. The actual Trans tune being...
20's are the new 17's didn't y'all get the memo? Now 24' spinners while hitting the whoops would be legit. I'm also going to downsize to 33" cuz #rubberbandlife
Seems like this has turned into a MPG thread! Sweet, I recently did 600 mile trip over Cascades from West to Eastern WA (not the longest trip) but lots of elevation change with average speeds of 75-80mph. My total average was 16.5mpg with 37's. Prior to that my 1,000 mile trek back from...
I'm 50/50 on this, I think in some circumstances it's handy to have especially for the masses. The implementation of it's pretty clever and seems to be where lots of Motorsports oriented Fox stuff is going. I have Fox 3.0 RC2's (triple adjustable) on my Can Am X3 and I still prefer those as I...
Yup, looks like I clearly botched that one. I was able to do Glare Free lighting, all the other main tweaks but this one got me. I was also rushing some being late at night and learned my lesson. Time to find a VERY long road to fix this....ugh
I really appreciate you sending me this!
I was confused since under the Forscan Speedometer Calibration instructions it references changing both PCM and TCM initialization and I could only find the PCM. I did see the TCM function under service procedures and did that so seems thats where I...
Quick follow-up to this. I just added 37's and reset the BCM settings (MPH spot on within .1 per GPS) as posted in #577:
726-15-01 C104 019A 0AAD
726-15-02 C126 8BB6
After that I did the PCM/TCM initialization and also reset the TCM shift module (not sure if that was needed). Now my 10AT is...
Thought I'd give a quick update on my thoughts having around 4k miles bone stock (35 Package) to now switching to a 37 setup pictured above last week. I recently did a 600 mile road trip and spent some time off-road in dried lake beds and FS Roads with around 12-16" of snow in places. I'll...
I'm more wondering if they are planning to make a 1000HD kit or it's more worth using their designed spacers with the equiv 1000HD bag for extra load handing and hopefully longevity? I've read the standard 1000 (non-HD) bags don't generally last that long.
My 23 has done it as well and is usually when I'm using Carplay. I recently did an APIM force reset through Forscan so hoping maybe that helps, I'm not sure.
I REALLY wanted gunmetal on my Avalanche as I'm 50/50 on black wheels. I find you lose the contrast against the vehicle and they can look a bit bland at times. With that said, the satin finish on these are nicer than other more matte black wheels.
Made the switch today from OEM Cast 35's to KMC Mesa Forged 17x8.5 +0 (23lbs) and OEM FP 37's. Suspension is stock 35 unmodified and no rubbing and fitment is spot on. Back is perfectly flush, front pokes maybe 1/2" which is slightly more than I'd like but manageable.
Couple Notes:
OEM Cast...

Might have missed it posted here but what is the OEM 37PP setting under the BdyCM Module for 37” Circumference in mm? Trying to adjust my tire size going from 35” to 37” and would like to use the OEM value.
I meant that if you put 1.0" Eibachs on a 35 truck this would effectively be 3/4" higher than a 37pp assuming they are starting 1/4" taller from the start. Mainly, getting at what is the minimum level requirements to gain proper clearance/travel for 37's and it seems the 1.0" Eibachs are about...
Interesting, so all things being equal the 37pp only sits 1/4" higher than a 35 in the front? The net from 1in Eibachs then is 3/4" (for 35 truck) which is close to equaling out what the 37pp bumpstops limit.
Not sure if I "had" to but I did. Fairly certain in normal glare free mode the fogs would be off with highs just like before. I now have mine on Glare Free (with baja fogs) and the output is amazing.
Since we were discussing this in the other thread and I have also been between these two options I have a few questions. In what situation are these topping out aggressively? I would wonder given there are significant amount of people that have the 1.5" RPG collars why the inconsistent...
