Shock extensions are recommended due to essentially maxing out the travel when raising the front suspension, so they are useful but not required. I found that a 2" crank didn't severly limit the shocks travel. a lot of people crank the stock keys and get an alignment and all is well. It's the amount you lift that adversely affects ride quality and requires new UCAs. It's basically the same concept as lifting a 1500 with just a different means. 2" is a safe bet that won't hurt anything. Now I will say that the last time I messed around with t bars was when I had my 03 HD, so it's been a while, but I'm sure the suspension is basically unchanged.

Thanks. I plan on getting control arms and shocks later once the factory shocks get worn out. I will do a little experimenting when I do to see if the extensions actually make the drop stop the down limit in the suspension or not. I am pretty sure they will. I am really just curious for other people doing it as I won't be adding them until I do control arms. I would rather the limit stay on the shocks like it is without extensions rather than beating the control arms on the frame.

Anyone ever try the BFG AT KO2s in a 275 70r18 on a 2015 2500HD? Searching all over the place and seeing a lot of people considering but haven't seen any confirmation if they fit with no rub. Not trying to change anything with the t bars!

I had 275/70/17s on my 2011 2500HD. No issues. Loved them. Looking to buy some for my 20s now.

I just put BFGoodrich All-Terrain KO2's, 275 70R18, on my stock 18's and am extremely happy with the outcome. Tested at full-lock and no rubbing of any kind, and not concerned that there would be any rub with suspension compression at full-lock/bumps.

 

Even though only .5" wider and 1" taller, they really do make a world of difference in the appearance. No real off-road testing yet but I am sure they will perform well.

I have 285/60R20 Duratracs on my 2014 2500 and they fit fine. I have the bars turned a couple times but I am not leveled. No scrubbing though.

      The Peckish Synapse

      Well that book won't sell many copies. Taking ones right foot off the loud pedal never gets applause. Funny really, It isn't that people don't know what to do...they just don't want to do it. But they will complain about it. About bad craftsmanship, about the cost of fuel, about the cost of part and repairs and mainly they complain that the solution while still possible isn't one they are willing to do.    I observe this daily. 'Gas cost to much!", they wail, while they mat it passing at 80+ mpg and scoot down the road like gas cost a dime a gallon. Then complain about the few that will lift and save both fuel and iron like they are owed and own the road.    Good thing they haven't an ounce of influence on my equipment. The rest I just laugh at. Stupid is as stupid does, right Forest?

      Today I filled up with 4.899 gallons of fuel at a cost of $4.899 a gallon. $24 bucks. 290 miles. 59.2 mpg. After my 4% COSTCO discount just under eight cents a mile.

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!

      Brake Pad Warning Message

      By TrueBlue · Posted

      I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.
