In a joint collaboration with RevMax, we are pleased to announce the world’s first true aftermarket torque converter for the ZF 8HP90 and 8HP95 transmission. In cooperation, we have designed the best torque converter available for the Hellcat 8HP90/95. All other converters that are currently for sale reuse ALL of the factory internals and just swap the stator out. There is no additional clutch capacity added or any other performance gains, just a stator swap While this works ok for some budget users, by no means is this a true performance converter. The RevMax converter uses none of the factory internals, this is a completely different design from the bottom up!

Our design is a two-piece bolt together. It allows you or your shop to change stall speeds and clutch configurations without ever sending it back to us. You buy one converter and that’s it. After that, you can handle your own refreshes, stall changes, and clutch changes! Our converter is almost 15% lighter than a factory converter or the Demon converter upgrade. This weight savings is instantly apparent as soon as you go WOT. Your engine will spin-up much quicker due to the decrease in rotating mass.

The front cover or engine side is made of aircraft spec billet 6061 aluminum. The solid chunk weighs over 60lbs before it is precision machined down to just 7lbs. The converter bolts are held in place by Mil-Spec thread inserts that guarantee the connection to your flexplate. A hardened crankshaft pilot adapter ensures that your converter will always run perfectly true. The impeller is a proprietary design as is the stator. Now let’s get to the heart of this converter, the lockup clutch system!

As you are aware, the factory converter lockup clutch begins to slip in the 900HP range. All other converters on the market are limited in clutch capacity to the stock amount of frictions and piston surface area. This proprietary converter design has many advantages over the factory and all other aftermarket converters. Our piston is almost 60% larger in surface area which blows away anything else on the market today. In addition, our modular friction design allows you to run as many as six larger, double-sided clutches which enables your converter to hold in excess of 2000hp. Imagine the possibilities! With just two of our larger clutches, we have more surface area than any of the competition. Three clutches give you 52% more surface area on up to six clutches which gives you 105% more surface area. Of course, most of our customers are happy with the big advantage 3 clutches offer but the future-proof upside is huge. You are ready as your build grows which saves you time and big money in the long run because you are able to add clutches and change stators yourself. No more sending in your converter and waiting weeks or months to get your old one sent back to you. Less downtime  = more racing.

We have multiple cast and billet stator options available to suit all setups. Best of all, you can mix and match stators at home and find your perfect setup all without ever sending in the converter. We also offer multiple piston heights and clutch setups to custom tune your own lockup firmness and holding capacity.

Stall speeds from 3000RPM up to 4500RPM are available!
