Reverse Piston Springs - HEAVY DUTY - SET OF 17

ATI Racing’s Reverse Piston Springs are a heavy-duty upgrade specifically engineered to dramatically shorten transbrake release times in Powerglide transmissions. Offered as a set of 17 springs, this high-tension assembly replaces the stock springs to deliver faster and more reliable reverse piston retraction under high hydraulic load, crucial for quicker reaction and reduced lag. Manufactured to ATI’s rigorous performance standards, these springs maintain consistent pressure over repeated cycles, supporting dependable transbrake function in both street machines and bracket racing setups.
