GM HD 3 Piece Crossmember

Pricing: $999.99


The WFO GM HD 3-Piece Crossmember is a great place to start your Straight Axle Conversion. It fits the 2000-2010 Duramax Diesel Trucks AND the 2000-2007 2500HD/3500 Gas Trucks. You can use the crossmember with a traditional 4 link setup or a radius arm design.

The three-piece design allows for easy maintenance to the transmission or transfer case when needed. It can be used with the stock transfer case or a 273-Custom Transfer case upgrade from Transfer Case Express. The center section of the crossmember is designed for automatic transmissions and would need to be modified (shortened) for manual transmissions.

The link pockets are 2 5/8" wide with 5/8" holes so you can run large 1.25" heims or Duroflex Joints.

It easily bolts up to the factory holes. Then you drill 8 additional holes for extra reinforcement.

It comes with all necessary grade 8 hardware and powder coated black for a sleek design.
