Because the Impala was made in such small numbers, GM didn't bother to design a specific proportioning valve for the SS - but our kit solves both problems! The Stealth Brake Bolt changes your brake pressure to 65% front/35% rear to reduce brake dive, even out pad wear, and firm up the brake pedal. The 'Bolt II' Brake Metering Bolt removes the flow restriction that causes the front brake delay, allowing all of your brakes to engage simultaneously and significantly improving your braking ability. Our kit includes both bolts.

Instructions included. 1 kit needed per vehicle. Only for vehicles with 4-wheel disc brakes.
