When doing an MX-13 compressor swap, you always want to go genuine OEM to avoid alignment and oil feed issues. This Wabco 440CC unit bolted right up to our 2015 Peterbilt 579 without any clearance headaches. Coolant and oil lines lined up cleanly. Checked build times after installation and it hit factory spec effortlessly. Motorspares Direct shipped it out immediately. Highly recommend for any shop working on PACCAR trucks!

We had a 2017 Kenworth T880 taking forever to pump up air pressure on morning pretrip inspections. After ruling out system leaks and checking the governor, we found the original compressor was passing oil into the air tanks. Ordered this genuine PACCAR 2139800PEX compressor along with a new dryer cartridge. Perfect drop-in fit with exact port alignment. Air tanks fill up fast now and stay dry. Fast commercial freight shipping and no core charge made this a great transaction.
