*NOTE* PLEASE MAKE CONTACT WITH US ON STOCK LEVELS, COMMON SIZES USUALLY ALWAYS IN STOCK, BUT NOT SO COMMON AND OCCASIONAL STOCK RUNOUTS COULD CAUSE DELAYS ON SHIPPING ORDERS. DESCRIPTION Once you have a GripTec pulley on your Trackhawk, a boost change is as simple as changing the outer pulley drive ring. All boost level changes require the appropriate PCM revisions and the proper supercharger belt. Please note that quoted boost gains are approximate, and that your results may vary. The 2.85" pulley is intended for street applications, while the 2.75" and smaller pulleys are intended for race applications or applications using supplemental injection.  Additional Information  We've found that the Gates K100572HD belt works well with the 2.75 and 2.85 pulleys and stock crank pulley (15-16psi). This part is available in our webstore. We've found that the Gates K100594HD belt works well with the 2.75" and 2.85 pulleys and ATI Crank pulley (17-18psi). This part is available in our webstore. We recommend purchasing the Hellcat Crank Pin Kit and completing this installation with your upper pulley upgrade. This part is available in our webstore. Custom tuning is required. Contact us for more information.  

Since the Hellcat first hit the market, it's been debated as to how much safer a clutched pulley just like the OEM decoupling 3.35" would be on modified IHI Hellcat superchargers. Litens comes through with their high quality heavy duty 2.85 pulley upgrade. Using the OEM design developed specifically by Litens this pulley will reduce stress and associated wear on your supercharger's bearings and rotors.Kit Includes:1 - 2.85" Litens Supercharger Pulley1 - End Cap (dust/tamper shield)1 - 17mm Install Tool1 - HD Belt This pulley makes approximately 15 PSI on Hellcat and Trackhawk Superchargers and 18-19 PSI on Demon and RedEye Superchargers at sea level. This pulley kit does require use of larger fuel injectors and custom engine tuning.Note 1: Pinning of the crankshaft pulley is not believed to be required with use of this pulley but no liability is assumed or implied by Sunset Speed due to any damage that may occur due to unpinned cranks.Note 2: Litens highly recommends against the use of additional idlers or heavy duty tensionsers and HD Belts with their pulley due to the higher risk of internal failure. Failure caused by running these other parts may not be covered under warranty. Warranty: 1 Year manufacturer parts warranty against materials and manufacturing defects from date of purchase. A great many owners of Hellcat-powered vehicles from Dodge and Jeep have learned that swapping to a smaller pulley adds gobs of power (with the necessary supporting modifications). The problem with the pulley swap options on the market over the past few years is that they lack the internal decoupling and isolating assembly found in the stock Hellcat supercharger pulley, but that has just changed. Litens High Performance – a division of the same Canadian firm that produces the stock supercharger pulley for the Hellcat Challenger, the Hellcat Charger, the Trackhawk, the Hellcat Redeye and the Demon – recently introduced the first decoupling pulley for the IHI superchargers on the modern Mopar monsters and it has a fitting name. The HellRaiser The HellRaiser pulley is produced by Litens High Performance and distributed by Tendeco to performance shops around North America. This pulley measures 2.85-inches and features the same basic structural design and the same internal decoupling design as the stock pulleys, but those stock pulleys are 3.43-inches (87mm). Where the stock pulley on the Hellcat cars and the Trackhawk deliver around 11 pounds of boost, the HellRaiser increases the boost pressure to 16psi. Development Details For those wondering, the HellRaiser pulley from Litens High Performance was developed with some very well-known members of the Mopar Performance community. Rob Laing of Litens (High Performance design team, and a drag racer himself) and John Lussier of Tendeco presented Hellcat and Demon owner Paul Georges with the idea. 

*DUE TO DEMAND ALL WHIPPLES HAVE A 12-16 WEEK TYPICAL LEAD TIME. DESCRIPTION The record breaking Gen 5 supercharger system is AVAILIBLE NOW for the Hellcat, Trackhawk, Demon, Redeye supercharged applications! The 3.0L Whipple Twin-Screw supercharger boasts insane, never heard of power potential compared to previous supercharger designs. Whether you are replacing the stock Supercharger for modest gains or going all out racing, the Whipple 3.0L will deliver the results you are looking for. Using the same technology that powers the 2021 Dodge Drag Pak, the Gen 5 uses Whipple’s patent pending dual pass, dual intercooler to achieve twice the amount of charge air cooling than any other supercharger system on the market. Couple that with the new 3x4 rotor combination, and the Whipple makes more power than any other positive displacement supercharger available today. The Gen 5 features billet supercharger rotors, machined right there in the USA at their facility in Fresno, CA. Whipple billet rotors are far superior to the stock cast rotors that fail with overspeed. The Gen 5 rotors are the latest in twin-screw technology, which offer higher efficiency levels over a broader RPM range, cooler air charge temperature and less power consumption than any of the stock 2.4, 2.7 or 3.0 offerings. To further improve on the performance potential, the Gen 5 Whipple features a unique 112mm throttle flange with an optional, billet 112mm throttle body to ensure inlet airflow matches the supercharger potential. Top that off with an all-new, high-flow cold air intake system and watch the records fall! Stage 1 Supercharger system is a direct OEM replacement, using stock fuel rails, injectors and stock throttle body (or current aftermarket throttle bodies). Stage 2 Supercharger system features the billet 112mm throttle body and billet -8AN fuel rails. Over 300HP capacity over Hellaphant 3.0L Supercharger Over 500hp capacity over Hellcat 2.4L supercharger Expensive porting not required to make power Massive, dual pass, dual core intercooler technology for twice the cooling area of any other PD SC for 6.2L Inverted design allows for oversized intercooler, each core is 2.125” thick, dual pass = 4.25” thick core Dual in, dual out intercooler for increased water flow 112mm opening for compatibility with stock TB, 102mm, 105mm and Whipple’s 112mm Billet rotors far superior to cast rotors for high rpm operation ¾ rotor vs 3/5, 33% lower male rotor speed Superior profile with shorter leak path Thrust retaining system for better bearing support Massive air inlet for high flow (porting not required to get power) Optional high flow cold air system Fits stock fuel rail, stock injectors or billet Whipple -8 rails Works with stock belt system and optional balancer options Works with electronic bypass control Works with stock TMAP sensors New over bearing 5-bolt supercharger pulleys Billet bearing plate and oil cover Custom colors available WHY WHIPPLE ? While others "claim" to be leaders, the truth is simple; Whipple are the true pioneers of twin-screw supercharging. For over 23 years, Whipple has led the industry with innovation after innovation. Whipple has more experience in supercharging applications then any other twin-screw or Eaton based positive displacement supercharger manufacturer. Whipple  brought the twin-screw supercharger to the US automotive market and has pioneered the "bolt-on" supercharger business. While others try to copy or follow, Whipple continues to develop new superchargers and new systems that not only look like a piece of art, they outperform the competition.
