Added Larger Tires? You Dropped in Power. Ford Has an Answer​


Ford Performance recently released Bronco calibrations for the 2.3L and 2.7L EcoBoost engines – M-9603-B23 and M-9603-B27. Now, as of Nov. 29, these calibrations support gear ratio changes up to 5.38.

“More importantly,” said Mike Goodwin, Engines/Drivetrain/Calibrations Product Manager at Ford Performace, “customers can now upgrade base models with M190 front drive units to the M210 with E-lockers. Now customers can go up to 37” tires and 5.38 gears.”

The M190 front drive unit (FDU) is found on non-Sasquatch Base, Big Bend, Outer Banks, and Black Diamond Broncos.

Goodwin reminds 2021-2022 owners upgrading from the M190 front drive unit to the M210 FDU (M-3002-446BF or M-3002-470BF) that they will need the calibration to reconfigure the driveline control module. You’ll also need new half-shafts: the same ones M210 FDU-equipped Broncos use (M-3429-BR).

If you’ve already purchased one of these performance calibrations, you can access the new ratios and module configuration capability by updating the ProCal 4 firmware.

More to Come​

Watch Ford Performance Parts for new releases: In addition to the currently available 4.46 and 4.70 ratios, FPP will be offering Bronco gears, FDUs, and complete axle assemblies in 4.88, 5.13, and 5.38 ratios.

Oh no, my poor wallet.

Edit— Just did the math... 108.475 final drive ratio if you have the manual transmission in 4x4 low with the crawler gear. You hit 3000 RPM going a grand total of 3 MPH on a 35" tire. Insane.

Its a trap, guard the wallet... what am I talking about?? 🤷‍♂️ Just do it... It'll make spinning the 35s effortlessly and better fuel economy could be a side effect... plus you could be one of the first...😆... That has some ROI, right???

Did you not get one? They offered them for 15 years.... there was no 2 year wait either, and much cheaper... you should have jumped on one... but they sold out now.
