Our S975 Drag Performance package for you 2015-2019 Dodge Challenger and Charger SRT features the following items from Livernois Motorsports:
Livernois Motorsports & Engineering's line of EvenFlo low temperature thermostats reduce the operating temperatures in your performance engine. This will allow for the engine to naturally make more power power, ensure consistent performance, and increase coolant flow to help extend engine component longevity.
- K&N High Flow Air Filter
Livernois Motorsports & Engineering evaluates many available air intake solutions available for these vehicles, and chooses what we feel provides the best balance of fit, performance, and filtration capabilities. By taking the time to analyze these selections, it allows us to offer what we are always known for, the best possible results that are designed to last the life of the vehicle. For the S975 Hellcat, we have found the High Flow Filter situated within the OEM airbox to provide ample flow, while ensuring performance and protection in all environments.
- Injector Dynamics ID1050X Fuel Injectors
Livernois Motorsports & Engineering always strives to offer the best available components for all of our packages, and for the S975 Hellcat we utilize the Injector Dynamics ID1050X line of fuel injectors, which our featured in many of our popular install packages. Proven to offer unmatched drivability, while supplying sufficient fuel flow to accommodate your high power levels, these injectors offer amazing consistency.
- Innovators West Harmonic Balancer with O/D pulley
Livernois Motorsports & Engineering carefully analyzes many available harmonic balancer systems available, and chooses those that meet our stringent quality, performance, and adaptability for our wide array of performance package offerings. For the S975 Hellcat offering, we utilize the Innovators West Balancer along with their triple-dowel and keyed crank pinning system.
- Livernois Motorsports Custom Supercharger Pulley
When developing our S975 Drag package we had one clear goal in mind. Finding the perfect balance of increased performance, with reliable blower speeds. In doing so, we determined that this necessitated a purpose designed and built supercharger pulley to work in conjunction with the Innovators West overdrive balancer.
- Livernois Motorsports Driveshaft
Our experience with these cars continually showed us that after a certain power level, the stock driveshaft is inadequate. Not satisfied with some of the existing designs on the market we set out to develop a driveshaft that would add durability, while keeping noise and harshness at a minimum. As a result of that, we have released our own, upgraded driveshaft offering for the Hellcat Charger and Challenger and utilize it as standard fare in our S975 package.
- Mickey Thompson Drag Radial Tires
One thing is for sure with all of our Hellcat upgrade offerings. The stock tires become borderline useless with any added power. Since our S975 package is all about making power, and utilizing it effectively, we decided to include these tires in the package. This will help ensure optimal dry weather traction, which means more acceleration and performance.
