TCI 374401 - TCI TV Boost Valves

TCI 374401 - TCI TV Boost Valves Details
Applications exceeding 450 horsepower can definitely benefit from the increased clamping force generated by higher line pressures. Depending on what pressure regulator spring is used, the TCI® 374401 TV boost valve will generate maximum line pressures from 275-300 psi. across the board. The 0.570-inch diameter boost valve has 41% more surface area than the largest OEM TV valve, raising pressure in Drive and Overdrive ranges.
TCI boost Valves replace stock in all 700r4 & 200 4r applications. The boost valve increases clamping forces generated by higher line pressure. The 890-374301 is best suited for applications stock to 450hp. The 890-374401 is best for applications exceeding 450hp (best when used with the low rev. boost valve 890-374410), and the low rev. boost valve will bolster line pressure to allow you to get the added line pressure needed when making that BIG horsepower.
