American Powertrain Releases High Tunnel Hump For The 1967-79 F-100

New from American Powertrain – the replacement High Tunnel Hump for the 1967-1979 F-100. This hump allows for additional clearance while being easy to install. See more details below.

Official Release:

American Powertrain now offers a new replacement High Tunnel Hump for the 1967 – 1979 F-100 pickup that provides additional clearance and easier installation. The new 100% gel coated fiberglass tunnel hump from American Powertrain is designed to work with both American Powertrain’s TKO and MAGNUM Pro-Fit transmissions. Unlike the standard factory steel hump for the ’67- ’79 F-100 pickup that has minimal clearance and required the factory hole to be blocked, this replacement offers a cleaner install with only one hole included for the shifter. Installation is easy using only screws and bonding adhesive.
