Question:

I want to verify the item below works with my 2025 GMC Sierra 1500 Denali Ultimate with the 6.2L gasoline engine. We bought a 2026 Keystone Passport 2870RL camper and a four point anti sway hitch, but Camper World could not adjust out the truck sagging. Firestone Ride-Rite Air Helper Springs - Double Convoluted - Rear Axle Part Number: F2609

Happy to help Tom, you've got a solid truck for pulling a Keystone. That combination should tow really well once everything is dialed in.

Yes, the Firestone Ride-Rite Air Helper Springs # F2609 are a fit for your 2025 GMC Sierra 1500 Denali Ultimate.

The Firestone air bags and a properly adjusted weight distribution hitch work very well together. The weight distribution hitch redistributes the load, while the air bags provide additional rear suspension support to help maintain a level ride and improve handling.

I'd recommend taking a closer look at the hitch setup as well. If there's still excessive sag after adjustment, it could indicate that the hitch isn't rated correctly for your loaded tongue weight.

If you let me know the make and model of your weight distribution hitch I can make sure it's appropriately sized for your Keystone.

I put these air shocks on my 2020 GMC Sierra Denali P/U and they fit properly and the ride is great. I keep about 15psi in the shocks all the time and give it additional pressure when pulling heavy trailer loads or if i plan on loading up the bed with a heavy load. More than a year later they still do the job and I am VERY glad that I chose these air shocks!

@Aggro appreciate you stopping by! I agree, keeping a small amount of air in the bags for everyday driving and adding pressure when towing or hauling is exactly what makes them so versatile. I appreciate you sharing your setup, What are you typically hauling?

I haul just about anything but the item(s) that I haul the most frequently are bags of deer corn. I usually buy 10-12 bags twice a month so at 50lbs per bag means about 500-600lbs per load. With those loads I sometime bump the shock pressure to 25psi but most of the time I just leave the pressure at the normal amount of 15psi. The shocks have no problem giving me a good level ride at that pressure,

@Aggro That's a regular workout for the Sierra, 500-600 lbs of deer corn twice a month definitely gives you a good feel for how the Ride-Rites handle a load. It's great to hear they're keeping the truck level without you having to constantly adjust the pressure. Are you feeding deer on your own property or managing hunting land?

I installed this on my 2021 Chevy Silverado worked great on lifting up the suspension and took out a he squat but to take out more squat you’re hitch would be I believe 20” from top of ball to the ground

Tom, There was no guarantee this would work for my truck based on e-trailer expert opinions. They had concern of the exhaust being in the way on the right side of the truck. Me being an engineer/gear head. Decided to purchase and modify to remove the concern. What I did was installed all the equipment and added exhaust header wrap around the area by the springs. I then painted the heat resistance on the wrap and have never had a problem since. I'm very happy that I can increase my support of my truck instantly.
