Note: Tuner kit requires custom tuning and a professional installer with custom tuning capability.  Click here to find a professional ProCharger installer near you.

Tuner Kit: This kit makes sense for someone wanting to perform custom tuning of the car and push the envelope in performance.  Will most likely be experimenting with alternative fuels and changing engine components like heads, headers, exhaust, and cams for the engine.


NOTE: All Chrysler/Dodge vehicles 2015 and newer have locked Powertrain Control Module (PCM) computers and they require an unlocking process in order to install a new tune.  Please click on link here for more details. The PCM must be shipped to Diablosport for unlocking so, please allow roughly one week. Another option is to purchase a second PCM directly from Diablosport ahead of the installation so, there is no downtime.  It is an unfortunate hassle, but unlocking is required with any tuning modification to Chrysler/Dodge vehicles.

  • Supercharger Finish Options – Satin (Standard finish), Polished (Code -P), or Black (Code -B) for superchargers
  • Supercharger Bracket Finish Options – Satin (Standard finish), polish (Code -PB), or black (Code -BB) for bracket assemblies

How our part numbering works

For any option that is desired all you have to do is put a "-" in front plus the Code and add it to the base part number shown. For example, let's say you wanted to order the 2018 Jeep JL HO System and wanted the following options: Black finish for supercharger, supercharger brackets, and intercooler.  In addition, the helical gearset option.  

The correct part number would be 1JK214-SCI-B-BB-BI-H

Larger Intercoolers

Our Systems and Tuner Kits include large air-to-air intercoolers (black finish option available) to keep air inlet temps low even under extreme conditions.  

Jeep JL ProCharger Supercharger System

No Major Modifications Required

Just bolt it on, slightly trim the fan shroud, install a provided tune with the HO System or a professional tune with the Tuner Kit, and GO!  Our ProCharger HO Systems and Tuner Kits are designed to be simple and easy-to-install letting you get your Jeep back on the road and hitting the trails.  The ProCharger belt drive system is easier to service than even the factory system, because the belt can be removed or swapped without any other component removal! We also mounted the supercharger head unit as high as possible for those JKs that will see some water/mud, and to leave more room for aftermarket suspension/steering parts. Click here to find a professional dealer nearby to help out with your Jeep.

Additional Options Available

In addition to supercharger upgrade options to our D-1SC supercharger, we also offer multiple finish options. The ProCharger head-unit and bracket can be finished in Satin Aluminum finish (standard), Polished Aluminum finish (optional), or Wrinkle Black finish for a more rugged look (optional). The head-unit can be outfitted with two different styles of internal gearsets: standard gears and helical "quieter" gears for a more subtle tone.

Helical Gears = Quieter Performance

For those wanting to have less noise when driving or off-roading, our helical gearset makes a lot of sense.  These gears are machined of high quality, hardened steel ensuring many miles of reliable, smooth performance.  Helical gearsets are ideal for those Jeeps with a stock or OEM exhaust.

Powertrain Warranty Available from 

A supplemental powertain warranty is available from Charter Warranty for those seeking additional protection ($7,500 total protection).  

NOTE: Vehicles must be less than 3 years old and 36,000 miles to be eligible for the warranty.  Click here for more details.
