Allison 1000 Transmission Crossmember for 1980–1997 Ford F-Series and Bronco
Once your Duramax is mounted, the Allison 1000 still needs a solid crossmember. Our transmission crossmember is designed to work with Carrick Customs Duramax engine mounts. It sets the Allison at the right height and location in your OBS Ford or Bronco, so you don’t have to measure, fabricate, or guess. This is a bolt-in crossmember that aligns with factory holes and only needs a couple extra holes drilled.
