Looking to Reduce Sag on a 2024 Chevy Silverado 2500HD Towing a 2025 Alliance Delta 321BH 8,253 lbs  

I drive the same truck and pull a 37 ft camper with a distribution hitch. My 2021 Forest River Surveyor Legend is just under 10,000 lbs loaded with 1,400 lb hitch weight. Yes the truck sagged alot. I bought the same Timbren that James D recommended. I do not have the bounce like I used to get and quite honestly, it rides so much smoother when it is loaded. Unloaded, the ride is exactly the same as stock since the Timbrens are not engaged. If you do not have 1-2 inch clearance unloaded, call Timbren and they will get it right. It was well worth the money. Since the Timbren engages with more weight, the sag is diminished by quite a bit. It is now maybe a 2 inches difference than when it is unloaded. I upgraded to a weigh safe distribution hitch with the timbrens and what an amazing ride difference. The installation seriously took 15 minutes. Jack up the rear of the truck by the hitch a little bit. Pop out the factory bump stops with a flat head screwdriver and soap up Timbrens and let the jack down. I never took the tires off. The Timbren is well worth the money.

Scott, We had a Chevy 3500hd towing an Alliance Paradigm 385FL. To level out the squat, we installed the Timbrens and they did the job. They also helped with the porpoising we were getting on bridge transitions. Helped smooth them out a bit. Loved them so much, we installed on our new 26 F450 too. Good luck, Bruce (A fellow Allie)

The unloaded ride suffers a little, but loaded they’re great pulling a 5W with 3100 on the pin it’s great. Level and much more stable. Good investment.

I have a 2022 Chevy 2500HD that I use for my roll-off dumpster business. Before purchasing these, I called Timbren and spoke with one of their representatives. She explained that they offer two different systems: one designed for carrying heavy loads in the truck bed and another designed primarily for towing trailers. I described how I use my truck, including towing gooseneck and fifth-wheel trailers, and asked which system she recommended. Based on my setup, she recommended the trailer version, even though I also haul heavy loads in the bed. I purchased that model, and I'm very happy with the results. They perform great when towing heavy trailers and also provide excellent support when hauling heavy loads in the bed. Overall, I have no regrets. If anything ever happened to the set that's on my truck, I'd order the exact same ones again without hesitation. Etrailer item #TGMRCK25D

I used the same unit as James, I’m glad I chose the Timbrens. 2026 GMC 2500, Towing 2026 Reflection 337, 11,700lbs. About an 1.5” squat a lot less chucking than standard suspension. I did have the RAS system which I did not like, it change the ride to a stiffer ride. Normal driving with the Timbrens have found no difference in the ride.
