It’s here!  We are proud to offer version 2.0 of our B-Series Cummins HD High Mount AC Bracket Kit.  Like the first, this kit is the solution to the low mount AC compressor mounting that makes Cummins swaps difficult in narrow chassis vehicles.

Since most conversions start with salvaged Dodge trucks, we utilize the versatile and affordable 1989-2002 Cummins diesel Dodge Truck “Sanden” Compressor.  Installation requires a 1994-1997 Dodge or 4 bolt 4BT* low offset fan support and pulley assembly.   This kit will fit 4BT and 6bt B Series Cummins engines.

Our current kit is compatible with the Gen 2 fan hub and these alternators:

  • Denso
  • Delco
  • Ford

Kits compatible with the 24-valve and Common Rail engines are coming later this year.

TROUBLESHOOTING

  • Are you using a 4 Bolt 4BT fan hub and pulley?  You need a longer belt.  This belt is not included in the kit.
  • Belt too close to the engine?  Add a shim or small washer under the bottom bolt of the tensioner mount plate.  This will adjust the angle of the tensioner and keep the belt from coming out of the fan hub pulley.  On rare occasions, two thin shims will be necessary, but always start troubleshooting with one (usually a 5/16″ washer). 

We assemble to order each Cummins HD High Mount AC Bracket kit.   A replacement Conversion Friendly Sanden style compressor has different rear AC line connections options.  These rear compressor heads can duplicate GM, as well as many other applications.    An external voltage regulator kit must be purchased to allow proper charging of the Dodge “Denso” alternator without the factory PCM.

    10/10 product! And great customer service. Currently swapping a 12 valve into my 78 F250. This mount and set up is hands down THE BEST OPTION for us narrow frame guys. Wish I would’ve found this before trying other options, not worth the time.

    Ordered this ac high mount kit for my land cruiser 80 in 2019. I have been to many times overlanding in bumpy ride and I can assured you this kit is tough because it is made out of steel unlike the older style billet aluminum where it will leak coolant overtime due to different metal expand at different rate. I would say the installation is straight forward, just make sure you do have a new thermostat and seal when you assemble the unit and apply plenty of anti-sieze on all bolt threads. Thanks Melissa and Jones for all the help as well as the update tensioner kit.
