Any body have trouble getting Camber in specs? What options are out there if so? Upper control arms? Camber kit bolts?

Has anyone looked at these struts? they advertise up to 2.5 of lift versus the bisteins wich lift 1.8 ??

It would be nice to get the look of the RC 2.5 kit without any spacers as the 2.5 kit is exactly the look i like on these trucks

Bilstein's also offer up to 2.75" but this depends on application (brand of truck). On our trucks they are good to 1.85". I think you will find the Summit's claim also depends on application.

I put on 5100s at the max height setting along with BFG KO2s in 275/60r20 and my MPG plummeted 3-4 mpg. Leveling kit and 1 size taller than stock and can't even get more than 18 on highway if I'm nursing it. Averaging 16.5. That's with hand calculating and pretty close to computer after recalibration with Hypertech. Anyone else similar issue? Thinking about lowering 5100s a setting or 2 and getting a lighter tire in stock size back on bc I didn't expect that big a mpg hit.

My truck reads an avg of 14 over 400 miles. Bilstein set at 3rd setting. KO2s 275/70/18. Average 13 mpg in town. Probably less since I haven't adjusted for tire size.

I believe the biggest hit is going from a street tire to a true A/T tire.

I've just read folks doing 2.5" lifts and putting bigger tires than mine on and claiming to get 21+ on highway. Maybe they are full of crap, who knows. My highway is barely more than city mpg. Running all stock I had a 300 mile trip that averaged 23, since these minor mods I can't do better than 18 highway so that's a really big hit.

What's in your diff? If you have the 3:08 I bet that might be why. Most people with the 3:42 haven't had as much trouble. The 3:08 is built for economy and larger tires and changing angles won't do well with lower ratios

 

Let us know

3:42 ratio, only 3.42 available in the All Terrain

Ive got 3.42 as well with 2 inch level and I can only get near 20 on highway like 19.5, but I drive 80 and the front end is shaped like a brick now. If I ran 60 I bet id see those 22mpg numbers.

 

When I go to an AT tire I expect to take a hit though.

Poor fuel economy?

 

With the larger tires, the speedo/odo counts revs, not distance traveled. Vehicle goes faster/further per rev.

 

IE the speedo is under-reporting your speed. Also under-reporting distance travelled.

 

You will need to apply a correction factor using your odometer's readings to get true mileage.

 

Use a tire size calculator to get the difference between stock and your size.

 

Apply the correction to your MPG calculations.

What was the weight of the previous tire vs new tire.

Its a pretty big jump, think stock is 43ish and that size K02 lists at 54.5.

 

Stock size K02 is 53.1

    • Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.
    • Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.
    • Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.
    • Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
