SpeedFactory Racing Heavy-Duty Detent Springs

SpeedFactory Racing's heavy-duty detent springs are upgraded, high-stiffness transmission springs designed for Honda®/Acura® transmission types (Hydraulic B-Series, D-Series, K-Series, H-Series, and F-Series). They offer over an 80 percent increase in spring rate over stock, providing firmer, more positive, and crisper gear engagement to reduce mis-shifts by providing higher pressure on the detent ball to secure the gear selector fork. Typically, installation is simple, as no transmission disassembly is required; the OEM springs are replaced by removing the external spring setting bolts.
