Dorman 949-356 air suspension compressor for the 2013-2018 Ram 1500 supplies compressed air to the nitrogen-filled air suspension. This Dorman air suspension compressor addresses a known failure: the original can fail when leaks push the motor past its duty cycle and melt the plastic piston.
- Dorman OE FIX design for the leak-driven compressor failure
- Durable aluminum internal piston
- Improved seals to prevent leaks
- Motor rated for greater thermal capacity to help avoid future failures
- New valve block inside a rugged die-cast aluminum case
- Vehicle try-on, corrosion and material testing for fit and service life
