One heavy-duty crossmember built to handle whatever drivetrain you're running — for K-series 4x4 Squarebodies.

This is the CFM Industries universal 4WD transmission crossmember, fabricated for K-series 4x4 Squarebody Chevy and GMC trucks, K5 Blazers, GMC Jimmys, and Suburbans. The factory crossmember was never designed around the drivetrain combinations people actually run in Squarebodies today — engine swaps, transmission swaps, doubler setups, and transfer case changes all throw off the factory layout. This solves that.

Built heavy-duty and designed to work across a range of setups, it gives your transmission and transfer case a solid, properly-located mounting point no matter what combo you're running. It can also pick up ground clearance over the saggy factory crossmember — a real benefit when you're wheeling.

Why It Works

• Universal drivetrain fit — built to handle engine swaps, trans swaps, doublers, and transfer case changes.
• Built for K-series 4x4 — fits K10, K20, K30 trucks, K5 Blazers, Jimmys & Suburbans.
• Heavy-duty fabrication — a solid, purpose-built mount, not a tired factory piece.
• Ground clearance upgrade — sits better than the saggy factory crossmember for more clearance.
• Swap & doubler ready — designed for the setups Squarebody builders actually run.
