DD1067 DIGITAL DELAY – ELITE RPM SWITCH$229.99
The Digital Delay Elite RPM Switch can handle up to four adjustable digital shift points (no chips to change or buy). The RPM can be adjusted in 100 RPM increments and is retained in memory even when power is removed. A selectable Shift Mode feature allows the shift output to be set for Normally Closed or Normally Open. The 40 Amp capacity shift output can handle most shifters without the need for an additional relay or wiring. Also, a handy shift test feature allows the testing of the wiring, shift solenoid, and shift cable without the motor running. This unit solves the problem of low or insufficient RPM drop between shifts, a common problem to our mud-racing customers.
NCRPM3000 RPM SWITCH W/DELAY$119.99
Prevent premature RPM Switch activation due to tire spin or converter flash off the starting line. An additional circuit in the RPM switch provides a 1 second delay in the activation of the RPM Switch. This delay feature only prevents the RPM Switch from activating in the first second. It cannot be used as a delay box. Use for a variety of functions such as activating CO2 or electric shifters, Nitrous solenoids, shift lights, timing computers or anything that needs to be activated at a preset RPM. Switch is easily adjusted using optional plug in modules. 12 and 16 volt compatible, and will work with all ignition systems, except Magnetos. 8 cylinder only. Single coil only.
NCRPM1000 RPM SWITCH$104.99

MSD8950 MSD RPM ACTIVATED SWITCH$119.99
This RPM-Activated Switch, has two activation wires; one to ground a circuit and the other to open a circuit. Simply plug in an rpm module and wire the Switch to the circuit you want to activate. When the engine rpm reaches that amount, the circuit is activated and will remain on until the rpm falls below that amount. This Switch can be used with stock inductive ignitions or an MSD Ignition and can handle up to 1.5 amps. Ideal for use with Air or Electric shifters. For use on 4, 6, or 8-cylinder engines.
Adjustable RPM Chip. Plug in RPM module works with most ignition controls including MSD and Shifnoid, and is adjustable from 1,000 to 11,000 RPM with the turn of a screw.
NC5300 UlTRA SHIFTER CONTROLLER$149.99
When used with 2 RPM switches, it will allow you to shift at 2 different RPM settings. Solves the problem of a RPM level that does not drop off between shifts, preventing your RPM switch from shutting off and resetting itself for the next shift. This is a common problem if you shift before your converter is locked or your tires are spinning, such as mud racing. These situations allow the RPM level to continue to climb instead of dropping off after the shift. Built into the controller is a RF Filter and Voltage Regulator to increase the reliability and accuracy of the RPM switches and a lock out switch to prevent the unnecessary reactivation of your shifter, once the transmission is in high gear. The controller can be wired for 1 or 2 shifts when used with 1 or 2 RPM switches.
