Unleash Ultimate Performance with the New AMD Transmission Tunnel - Perfect for 81-91 Chevy GMC C/K Squarebody Trucks and SUVs that are swapped!

AMD has developed an all-new solution to your engine and transmission swap clearance needs! 

July 2, 2024 – Enhance your 1981-1991 Chevy GMC C/K Squarebody Truck, Blazer, Jimmy, or Suburban with the all-new AMD Performance Style Transmission Tunnel. This innovative transmission tunnel is meticulously designed to offer optimal clearance for transmission swaps, replicating the benefits of the factory 4x4 floor without the necessity of replacing the entire floor pan.

Designed to suit C10, C20, C30, K10, K20, and K30 models alike, the AMD Performance Style Transmission Tunnel is a versatile choice for enthusiasts looking to upgrade their Chevy GMC C/K Squarebody Truck or SUV. We have tested a 4WD carpet kit with this tunnel installed, and it worked seamlessly as this is designed after a factory 4WD floor pan. 

Installation Tips: Ensure you verify your application before ordering to achieve a perfect fit. This cover is designed for easy modifications, allowing for custom applications that do not require floor shift or transfer case cutouts. 81-83 trucks may need some additional fitment at the rear of the tunnel. 

Achieve the clearance and functionality you need for your classic Chevy GMC vehicle without compromising on quality or performance. Upgrade with the AMD Performance Style Transmission Tunnel today.
