Carrick Customs Ford ZF6 Transmission Crossmember - 1980-1997 Ford F250/F350

ZF6 Transmission Crossmember – OBS Ford (1980–1997 F250/F350)

Perfect for ZF6 Conversions | Works with Cummins Swaps | No Floor Mod Needed

Looking to convert your 1980–1997 F-Series truck to a ZF6 transmission? Our updated and re-released ZF6 Transmission Crossmember is engineered to bolt directly into the factory frame holes, making installation clean and simple—with no transmission tunnel or firewall mods required.

Whether you're running a stock setup or a lifted truck, this crossmember is built to maximize driveline clearance and maintain compatibility with aftermarket suspension systems like radius arms and 4-link kits.

🔧 Key Features:

• Direct bolt-in for 1980–1997 F250/F350 frames

• CNC-cut 1/4” steel construction for maximum strength

• Large driveline drop section ideal for stock and lifted trucks

• Bolts to inside of frame rails (not under), clears radius arm brackets

• Great for Cummins conversions (requires new hole locations)

• Works with trucks that still have worn OEM body mounts

• Includes optional shims for fine-tuning transmission height

📦 What’s Included:

• Main Crossmember

• Driver & Passenger Side Frame Brackets

• Shims (for extra clearance if needed)

• Grade 8 Hardware

• Installation Instructions

🛠 Notes:

• Requires drilling two holes on the driver side for mounting

• Floor pan heat shield may need to be bent or removed

• On some crew cab or single cab trucks, you may need to trim a gusset on the underside of the cab for transfer case clearance

• We highly recommend replacing worn-out body mounts with S&B Silicone Body Mounts for better alignment and added clearance

This is the strongest, cleanest, and most compatible ZF6 crossmember available for the OBS Ford platform—whether you're staying all-Ford or throwing in a Cummins. Built for real-world installs. Built to last.
