Key Features:

• Pro-Dial Board Outputs - (2) Fiber optic outputs capable of controlling 2 Pro-Dial dial boards.

• Z-Force - Eliminates the "pressure" issues associated with conventional transbrake methods. (Z-Plus Models Only)

• Standard Mode - Configurable transbrake button modes work in either standard or Z-Force. (Z-Plus Models Only)

• Bump Up - Separate button allowing the opportunity to "Bump Up" (adjustable to the .001sec. increments) without losing the chance to "Bump Down".

• Bump Down - Correct for late reactions (adjustable to the .001sec. increments).

• Compact Size - 4.5" Width x 3.5" Height x 2.75" Deep

• Automatic Crossover/Crosstalk - Enter dial-ins, react to the first "flash" and let the box do the math.

• Double-Hit - Take two "shots" at the tree and leave on your quickest reaction.

• Large LCD Display - Blue backlight for easy day/night viewing.

• Quick Set Switches - Allows nearly instant changes to any setting.

• Run Info - Automatically displays reaction differential and "Bump" counts.

• Transbrake Lockout - Prevents accidental transbrake lockup (adjustable timer).

• Flinch Protection - Prevents early jumps.

• Full Tree/Pro Tree - Ability to enter two different run programs.

• Timer - Single (4-stage) timer to control throttle-stop, shifter, nitrous, etc. (Pro-Cube1 Models)

• Timers - Three (3), (2-stage) separate timers to control throttle-stop, shifter, nitrous, etc. during the run. (Pro-Cube3 Models)

• Pro Stage - Allows staging at an idle for both Full tree and Pro tree for improved concentration and consistency. Goes to full throttle when transbrake is activated on Pro tree and waits until your tree starts on a Full tree.

• Linelock - Versatile output for connecting linelock, launch-control, throttle stop, etc.

• Reset Switch - Instant stop of the delay box cycle.

• LED Indicators - Status lights show when each output is activated.

• Overload Protection - Self-protection from overloads and shorts on all outputs.

K&R has built a reputation for engineering precision, making the Pro-Cube Plus a trusted choice among serious competitors.

Performance Benefits & Key Features

K&R Pro-Cube Plus Timer Delay Boxes are designed to deliver precise delay adjustments and consistent signal output under race conditions. Key features typically include programmable delay settings, cross-talk prevention, and compatibility with transbrake systems and throttle stop controllers. These functions help racers refine launch consistency and minimize variability at the tree.

Competitive drivers prioritize fast processing speeds, durable circuit board construction, and intuitive user interfaces. The Pro-Cube Plus platform is engineered with high-quality electronic components and rugged housings to withstand vibration and repeated use in high-performance drag racing vehicles. Reliable electrical connections and stable power input contribute to dependable operation during critical race moments.

This delay box is ideal for bracket racers, Super Comp competitors, and sportsman drag racing classes where precise reaction time management is essential. When paired with compatible race wiring systems and ignition components, it becomes a central part of a professional-grade race electronics setup.

Fitment, Compatibility & Applications

K&R Pro-Cube Plus Timer Delay Boxes are compatible with a wide range of drag racing vehicles, including GM, Ford, and Mopar-based race cars configured with transbrake-equipped automatic transmissions. They are commonly installed in purpose-built dragsters, door cars, and bracket racing machines.

Installation typically involves integration with the vehicle’s existing electrical system and transbrake circuitry. Because they are designed specifically for motorsports use, these timer delay boxes are not intended for daily drivers or street vehicles, but rather for track-focused competition builds.
