Bad ignition coils are sometimes an overlooked cause for a vehicle that won't start, or is losing power and vibrating. JR Race Car Jr. Dragster stock Briggs coils bring your system back up to full strength, amplifying the battery charge into the high-voltage current your spark plugs need to fire up. These coil kits are stocked for multiple sized horsepower engines.

JR Race Car kill switches are mandatory for NHRA competition. These important safety devices are designed and engineered to allow the driver to shut off power to the engine and safely control the vehicle if a failure occurs with the primary switches on a Jr. Dragster car. Available in your choice of manual or electrical applications, both types of kill switches meet NHRA rule requirements.

JR Race Car cylinder head temperature (CHT) sensors are direct replacements for MyChron data loggers. These CHT sensors benefit Jr. Dragster engines by providing accurate, direct cylinder head temperature readings, which help drivers optimize engine performance for consistent, powerful passes by preventing overheating, maintaining fuel efficiency, and identifying and helping to solve engine issues in real time. Features and benefits of JR Race Car MyChron EGT Probes: * Consistent engine performance—the CHT sensors help ensure the engine is operating within its ideal temperature range, a crucial factor for consistent power delivery and successful racing * Helps prevent engine damage by monitoring the temperature of the cylinder head, these sensors help prevent overheating and potential damage, such as head warping, which is especially important in air-cooled engines * Real-Time Data for optimization—the CHT sensors provide immediate data, allowing drivers and crew to adjust the air-fuel mixture or power settings to achieve optimal performance for each pass * Enhanced fuel efficiency, accurate temperature readings can help in optimizing the air-fuel ratio, which leads to better fuel efficiency and prevents fuel waste * Unlike other sensors that measure coolant or air temperature, CHT sensors provide a direct measurement from the cylinder head itself, offering a more accurate representation of the engine's true temperature

JR Race Car MyChron EGT probes offer benefits such as performance optimization, engine health monitoring, precise tuning, and proactive diagnostics. The EGT (Exhaust Gas Temperature) probes provide real-time data on combustion efficiency and engine conditions, helping to adjust the air/fuel mixture, ignition timing, and other parameters for better performance, longevity, and the ability to detect potential issues like lean/rich conditions or misfires before they become serious problems. Features and benefits of JR Race Car MyChron EGT Probes: * Performance optimization—EGT sensors measure exhaust gas temperature, a direct indicator of combustion efficiency, allowing racers to fine-tune engine settings for maximum power and efficiency * Engine health and diagnostics by monitoring EGT, you can identify potential issues like lean or rich fuel conditions, which a high or low temperature indicates, respectively (this helps in diagnosing engine problems early) * Improved tuning consistency—once a desired performance level is achieved, you can use the maximum EGT temperature as a benchmark, striving to hit that same target in future races for more consistent performance * Misfire detection—the sensors can detect sudden temperature changes in specific cylinders, which can signal a misfire, allowing for preventative maintenance before it affects performance on the track * Real-time visibility—EGT data provides valuable real-time insight into how an engine is performing at speed, especially with increased airflow * Legally required data—in certain racing series, like Junior Dragsters, monitoring EGT is the only legal and reliable way to ensure a proper motor tune-up * Proactive maintenance—data from the EGT probe facilitates a better understanding of engine performance over time, enabling more effective preventive maintenance and reducing the risk of costly repairs

JR Race Car Jr. Dragster coil brackets are designed to allow you to relocate the coil on your 5 hp Briggs block so that you can use a smaller, lighter 3 hp diameter flywheel. They provide less reciprocating weight, which means quicker acceleration. JR Race Car Jr. Dragster coil brackets are offered in a choice of great anodized finishes.

One of the most important safety features in a race car is a way to quickly cut the power. JR Race Car terminal blocks are designed to make it easier to wire the "kill switch" in your Jr. Dragster. These double-row screw panel blocks have barriers to protect each circuit from errant wires, and they meet NHRA safety requirements. Sometimes the difference between catastrophe and light damage comes down to the flip of a kill switch. Wire yours correctly with JR Race Car terminal blocks.
