1958 GMC S300 Performance and Racing Products

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

Knowing your coolant temperature can help to prevent burn injuries. Thermo Cap, with its built-in calibrated thermometer, indicates the coolant temperature. This is useful information prior to cap removal. Never attempt to remove Thermo Cap when the coolant temperature is very hot. The escaping hot coolant and steam may burn you. Check the Thermo Cap temperature indicator to determine if the coolant is cool enough to make removing Thermo Cap safe. If the coolant is very hot, then thoroughly rinse the radiator with cool water, until the coolant temperature drops into a cooler safe zone Thermo Cap’s integrated coolant reclamation valve works great with your coolant recovery system. Your radiator can reclaim coolant from your overflow bottle. Wide 30 degree to 270 degree Fahrenheit temperature range. Calibrated in centigrade and Fahrenheit. Color-coded temperature ranges.
