Rear Syspension Enhancement With Air Bags, Air Tank, and Remote - Good For Air Horns Too

Question:

I have a 2020 GMC 3500 HD 4X4 dually truck. I want 8000 lbs Timbren airbag rear suspension with mounting brackets for frame/axel. HD air compressor system with remote/wireless control. 2.5 gallon air storage tank. Able to add train air horn.

If you want the Timbren Springs rated for 8000 pounds you will need the Timbren # TGMRCK25D Rear Suspension Enhancement system. This system is quick and easy to install and much more cost effective compared to adjustable air bag systems. Please note that the springs are rated for 8000 pounds but does not change or add to your vehicle's weight capacity.

If instead you want an adjustable air bag system I would recommend the Air Lift # AL88341 air helper springs which include internal jounce bumpers which is important if you have an air bag or air lines failure. (Note that the air bag systems have a 5000 pound capacity.) These could have the air pressure manually adjusted, but since you prefer an onboard air compressor I would recommend the Air Lift # AL74000EZ which includes your compressor, air lines, wireless controller, and EZ Mount system for a no-drill installation.

For your air tank I recommend the Bulldog # BDW42005 2-1/2 gallon tank with 1/4” and 3/8” NPT ports.

Hopefully you have a source for that "train horn" since we do not carry then.
