Yes, he does

No I don’t. The factory suspension is removed and a 6” suspension lift including coilover is installed.

You have the 2" stock suspension lift then added 4" body lift?

No. The at4 has a 2” lift already, that is removed, then a 6” suspension lift is installed. Netting 4” of lift over the at4

Definitely misread the original question haha. Sorry for the confusion

Anyone else have these Fox 2.5’s installed on their truck yet? I’m installing my kit this weekend. I ordered a 35x12.5x17 tire with a 0 offset method wheel with a 4.75 back spacing. I’m hoping this 3.5” kit will clear without too much rubbing.

I have a 2020 AT4 Carbon Pro - I did the 2.5" lift (so 4.5" overall) with fox 2.5 coilovers  - I have Method 18 x 9" NV's with 18mm offset - they did not clear the tie rod, so we had to go with spacer and wheel lug extender to gain about 1.25" of backspacing, so clear the tie rod.  The method -12mm would be the recommended fit.   With 20" the tie rod will go inside the wheel radius, making that more flexible for offsets.

 

With 17" you will have the same issue I had, but not as bad due to 0 mm offset - might barely fit, but if not with a 1/2" spacer you should be good to go on the tie rod issue.  But you will need to do some trimming to fit the 35's.  Pinch point will be the front fender where it tapers in - you only have 2" - going with 35" over stock 33's should eat all that up.  I will be very interested to see how yours turns out, as I am looking to get new wheels and larger tires - so if you fit 35's will be interesting to see what all is invovled.   I still have stock 275/65/18 duratracs on mine. 

 

Here are some photos showing clearance - FYI - no issue on inside clearance on steering knuckle for tire - 4" of inboard room at least - so 12.5" section width will be no problem over stock 11".

Awesome truck! Thank you for the response. All these makes me nervous haha. I hate that you get different answers when you talk to different companies or people. Dirt King, Fox and Camburg All said I’ll be fine. Method recommended 0 offset with a 4.75 back spacing to fit the 35x12.50x17 on my Silverado. With that said the wheel wells are different from the Silverado to Sierra. So I’m keeping my fingers crossed for a smooth install.

How much smoother is the ride with these new shocks compared to the stock ones?

Tough question to answer - the OEM mono tube Rancho's actually ride pretty good on the street.  They are way too soft for off road blowing through the stroke very quickly and bottoming out.  But overall I found the OEM ride quality to be very good on the street.

 

The Fox/BDS set up is more flexible with DSC adjustments on front shocks for compression and rebound - at full soft or a few clicks odd the ride is excellent, however it is "firmer" than stock.  I would consider it comfortable, but if you don't like a firm ride, you would think the stock truck was smoother on the street.  Off road, no comparison with the better shocks and lots of adjustments you can really dial in the shocks and enjoy the truck.

 

If you like the stock ride - you may think this is too firm - if you don't like the soft stock ride, then this offers the best of all worlds with total dial in flexibility - on the street I run 2 clicks from full soft on compression and rebound right now.  Will try softer after some more miles on the shocks and springs for full break in.  

 

Overall it meets my needs and expectations and I am glad I did it.  I like this set up much better than the Ready Lift SST kit, with stock shocks I had on my 2019.  It is not for everybody, but if you are familiar with adj. off road shocks you will be pleased.

Thanks for the detail! Any reason you went with Fox over King?

    • 10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O. 
    • Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.    
    • apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
    • yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
    • 286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔
