Originally manufactured for the Stage-Right type transmission brake application for the 200-4R transmission, these brackets are designed to prevent accidental up shifting into Overdrive, Neutral, Reverse or Park. The release button on the shifter handle must be used to shift from Drive to Overdrive, Neutral, Reverse or Park. Laser cut from 11 Ga. Type 304 stainless steel, these Shifter Detent Brackets are a direct bolt in replacement for the original bracket and use the original bolts. No modification required. Great for racing with the stock shifter.
