Comparing Timbrens and Air Bags for a 2014 GMC Sierra 2500

Question

Question:

I just purchased a 34’ 5th wheel trailer with about 2250# of tongue weight. Currently the trucks squats about 2.5”-3” once hooked up. I’m looking for a rear suspension enhancement that will maintain the factory bed height with trailer. What would your recommendation be for my vehicle? Timbren SES versus airbags for a 2014 GMC 2500 Duramax?

The two most popular suspension enhancement options for a 2014 GMC Sierra 2500 are the Timbren Springs part # TGMRCK25D and Firestone Air Bags part # F2613. I recommend the air bags as they are adjustable so you can always get the perfect level of comfort and support. The air bags will also get you closer to level when compared to the springs above. The benefit of the Timbrens is that they are easier to install and don't require any adjustments.

If you do go with the air bags, you can take a look at the video below of when I installed these on a similar model year. It would also be worthwhile to consider an on-board air compressor, the Air Command F3 Compressor System part # F2589 but this is optional.
