Yes I have is set with the 1mm disk (Minumim Tension), for spring spacing and I raised my truck in the rear 1.5". You can go 2mm and I think 3mm if you need.Minimum. We are on our way to TN from GA.. My wife is driving and stated she cannot believe and stated she can not belive the difference.

Most 1 ton trucks come with the factory overload spring, which need to be removed for installation of RoadActive Suspension. Removing the overload allows proper fitment and ensures the system works as intended. The RAS® Mega-Duty kit will reduce squat and provide significant improvement vs the factory overload spring.

Any time I get around 1,100–1,300 lbs of tongue weight, the rear of my truck ends up more than 3+ inches lower than the front. In my opinion, that's not a safe situation. The RAS completely solved that issue for me. Not only did it level the truck under load, but it also improved the unloaded ride quality. As an added benefit, it virtually eliminated axle wrap and noticeably reduced sway, both when towing and when driving unloaded. For my setup, the RAS has been one of the best suspension upgrades I've made.

After driving back from South Carolina this morning, I can confidently say the unloaded ride is considerably better with the RAS installed than it was without it. The truck feels more stable, smoother over bumps, and overall more controlled. I wasn't expecting such a noticeable difference when unloaded, but so far I'm very impressed with the improvement.

Which ones did you get the HD or MD? After driving back from South Carolina this morning, I can confidently say the unloaded ride is considerably better with the RAS installed than it was without it.

Not true! I have been runing them since 2006 F250! suspension component that works as a sway bar, a traction bar, and a helper spring points directly to the RoadActive Suspension (RAS) kit. Works as a sway bar, a traction bar, and a helper spring.

Has anyone run these on their 2500?

Same no dirt roads, so I put it in 4hi on a straight stretch of road, set the cruise to 45, and go.

Does our 4-wheel drive system need to be exercised? If it is not used a lot?

I have a 2026 SLE with most of the options, and it tows great.

Can you put one in the front diff in our trucks?

You have been weighed, measured, and found wanting ( A Knight's Tale)!

Yes, when we put the car up for the winter. We run all ethonal out and add rec gas with stabilizer. Otherwise, as you know, it will attract too much water sitting for the winter. Our race car was built to run high ethonal, so from the fuel cell to the injectors are braided ethonal safe lines. Have not had any problems. But last year, my mother ended up in the hospital, and I took 3 months off, and the car was a true PITA to get running again with the old VPE85.

We run VP-X85 in our race car. But I was running Rec gas because I fill up the boat at the same time and was getting 50 cents a gallon off.

Love that color!!

I second the Dueller Ascent AT.

I agree, it must be a better compound. The difference is not subtle, either at low speeds on boat ramps or on my steep driveway. The Goodyear would spin and then gain some traction, and the Bridgestone do not. Before this truck, I had AT3W, and they would also spin. I am sure many are better in the dirt, but that is not my use case.

The main reason I did not run the KO3 is the siping is only halfway through the tread blocks. And drive in too much rain.

I only run top-tier fuel. But recently, with my Chevron discount, I have been running 90-octane rec gas, no ethanol.

Thank you.

Maybe I have not towed heavy enough. I cant tell the difference.

Does anyone know if the L8T can advance timing i.e., could it advance it enough to take advantage of 93 octane while towing on a hot day, not to pull timing due to pinging? Per AI. No idea if it is true. Yes, a GM truck with the 6.6L L8T V8 engine can benefit from 93 octane, though the gains depend on how you use the truck. [1, 2, 3, 4, 5] Because the L8T features advanced engine management and variable valve timing, its computer will automatically advance the ignition timing when it detects higher-octane fuel. The primary benefits of 93 octane in an L8T include: [1] Improved Towing Performance: When pulling heavy loads or driving up steep grades, your engine runs hotter and is more prone to engine knock. The ECM will pull timing to protect the engine on lower-octane gas, whereas 93 octane allows the engine to maintain full power under stress. [1, 2, 3, 4] Better Throttle Response: You may notice a sharper throttle feel and slightly better low-end torque. [1, 2] Maximum Output for Tuners: If you add an aftermarket handheld programmer, the engine can be fully optimized to take advantage of 93 octane, yielding noticeable horsepower and torque gains over the factory tune. [1, 2, 3] If you are just driving unloaded without a trailer, the standard 87 octane recommended by GM is perfectly sufficient and cost-effective. However, if you are regularly towing, hauling, or looking for peak performance, 93 octane is highly beneficial. [1, 2] If you want to optimize your truck's performance, tell me: Are you planning on adding any aftermarket tuners or programmers? How often do you use the truck for heavy towing or hauling? I can help you decide whether the premium fuel upgrade is worth the cost for your specific driving habits.

Banks diff cover added. For those who have not greased their 9 zerks in your frontend, do it. Mine were bone dry.
