Biondo Spare Air Solenoid Cylinders

Sam Biondo Racing spare air solenoid cylinders are components used in drag racing applications, primarily with air/CO2 shifters and throttle stop controls, to provide consistent and precise pneumatic operation. Biondo solenoids are known for specific features, such as low current draw in electric versions (around 1 amp) and designs that resist false activation from hard vibrations. They're available in square or cylindrical configurations, depending on the specific application. These replacements are manufactured by racers for racers, following the philosophy of creating durable, high performance products that solve real-world racing needs for improved consistency and reliability. Key features and uses: * These solenoids act as an electric-over-air (pneumatic) valve that is activated by an electrical signal (usually from an RPM-activated switch or delay box). This activation controls the flow of compressed air or CO2 to an air cylinder, which then physically shifts the transmission or engages/releases a throttle stop mechanism. * Applications: -- Air Shifters: Used to provide consistent, repeatable shifts activated by a set RPM, rather than relying on manual shifting -- Throttle Stops/Starting Line Control (SLC): Used to control engine RPM at the starting line or during a race for consistency, particularly helpful in "Crosstalk" bracket racing * Components: They are part of a larger system that typically includes: -- A CO2 bottle and regulator -- The air cylinder itself, which performs the mechanical action -- Tubing and fittings -- An RPM-activated switch or a delay box

Sonnax Pressure Regulator and Shuttle Valve Kits

Vehicles with a GM 8L45 or 8L90 automatic transmission may exhibit high or low line pressure that results in harsh/soft shifts, burnt clutches, loss of cooler and lube flow, and overheating of the transmission and converter. These problems may be caused by wear of the pressure regulator bore casting at the VFS signal port area and/or at the shuttle valve sleeve. Wear at the inboard port of the pressure regulator bore allows VFS (throttle) signal pressure to leak, preventing proper action of the pressure regulator valve and potentially allowing it to remain in the low line pressure position. Wear of the shuttle sleeve due to continuous oscillation of the shuttle valve creates a path for balance line pressure at the pressure regulator valve to exhaust, resulting in excessive low line pressure. Sonnax drop-in pressure regulator and shuttle valve kits restore hydraulic integrity to the lineup by addressing wear that subjects the transmission to either excessively high or low line pressure with upgraded materials and unique designs. The pressure regulator valve has been designed with a lengthened spring pocket spool at the VFS signal port area, which provides over double the sealing capability to this critical end of the valve and allows it to operate in unworn portions of the bore. The length of the critical shuttle valve diameter has been significantly lengthened to provide better sealing and durability of the assembly. Additional details: * Hardcoat anodized aluminum valves and highly wear-resistant billet aluminum sleeve combat premature wear * Pressure regulator valve VFS signal spool 200 percent longer than OE and operates in unworn area of the bore * Critical shuttle valve spool made 30 percent longer than OE for added sealing and durability * Drop-in Zip Valve parts install quickly and easily Kit contents: * Pressure regulator valve * Spring * Shuttle valve * Shuttle sleeve
