The B&M Megashifter has it all, form, function and classic style. This all adds up to bring you a quality shifter that's been one of the most popular automatic shifters of all time. The light truck Megashifter is better suited for truck and bench seat applications with its overall height of 14.85-inches tall (2.25-inches taller than #80690 Megashifter.) The positive ratcheting action won't allow you to over-shift and miss a gear at that critical moment, along with the reverse lockout feature meets NHRA/IHRA safety rules for those weekend grudge races at the track, while the look and feel of the T-handle and accordion style shift boot really shows off its racing heritage. Other features include a black console that you can trim to match the contour of your vehicle's floor, 5-foot long shifter cable, cable brackets, transmission shift levers, chrome plated top plate with lighted gear indicator and everything needed for an easy at home installation. An optional T-handle with a 12-volt button is available separately for actuating a trans-brake, nitrous oxide or other accessories for the hard-core performance enthusiast. This shifter fits most popular Chrysler, Ford and GM 3 and 4-speed automatic transmissions. Note: AOD transmissions require optional kit #40496, GM 4L60E through 4L85E transmissions with PRNDL switch will require optional kit #70499. Overall Dimensions - 14.9L x 6.4W x 14.8H
