How To Prevent Front And Rear End Porpoise On My 2020 Chevrolet Silverado

Question

Question:

I have a 2020 Chevy Silverado with the 6 cyl diesel engine. I tow a travel trailer that is 5200lb base weight ... probably 6000lb loaded. Also, I am using a load equalizing hitch, but the front end will porpoise a bit on bumps. Looking at Timbren TGMRCK15S or SumoSprings SS45FR. There is a huge weight capacity difference between these two 7100 lb. With my set up which do you recommend? Or do you recommend another product?

Suspension enhancement may help you, but first I would make sure that your Weight Distribution system is rated and set up correctly. If it is, then you can go with some sort of suspension enhancement. Both the Timbren # TGMRCK15S and the SumoSprings # SS45FR are rated enough for your rig. The biggest comparison of the Sumos and Timbrens is how stiff and rigid they are when unloaded. Timbreens are stiff and affect your truck when it's unloaded a lot more than the SumoSprings. If this were me, I would go with the SumoSprings because it will give me a better ride quality when not under load.

I checked with Sumosprings and the #SS65FR and the dimensions are 5 inches tall by 4 inches in diameter without the spacer.

If you are looking for the best option to get rid of sag on your 2022 Chevy Silverado 1500, you will want the Firestone Ride-Rite Air Helper Springs #F2609. These offer up to 5,000 pounds of load leveling capacity at 100 psi, but can then be deflated…

For your 2020 Chevrolet Silverado 1500, I recommend going with a jounce-style spring. This is very low maintenance, whereas air suspension requires you to maintain correct psi levels etc. This setup will also keep the factory ride quality since they…

For sag from towing a trailer the best recommendation I can make is actually a weight distribution system. Suspension enhancement will help level your truck while towing. But the advantage to a weight distribution system is that it levels the vehicle…

Hey Dustin, thanks for reaching out! I will recommend SumoSprings over Timbrens all day everyday because they are much more forgiving when the vehicle is unloaded. We've actually joked around here about how the Timbren kits will either give you…

Answer 8

It sounds like the purpose of getting the air helper spring would be to counteract the 1 inch compression you're getting in your rear suspension caused by the pin weight of your 5th wheel. If that's the case, I believe that the AirLift 5000…

If you are considering Timbrens like the #TDR1500DQ and the SumoSprings like the #SSR-307-47 for your 2022 Ram 1500 4x4, I recommend the SumoSprings #SSR-307-47. The SumoSprings will offer the same quality as the Timbrens in terms of suspension…

Answer 10

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

Personally I wouldn't go with Timbren's for your needs. They're essentially rubber bump stops that prevent your suspension from flexing when weights placed on the rear of your Canyon. The major issue with them is comfortability when you…
