SST Launches “Hellephant” Tremec-Swap Kits Available Now!


The 1968 Dodge “Super Charger” Charger Concept incorporates modern touches, including the new 1,000 horsepower “Hellephant” 426 Supercharged Mopar Crate HEMI Engine, shown in background, to reimagine one of the most iconic vehicles ever built by FCA US.

Mopar’s new Hellephant crate engine has put everyone into a drooling daze, but one thing a lot of people haven’t thought about is how to get all of that power to the pavement. A run-of-the-mill 833 4-speed or 727 automatic is probably going to puke up a mess of metal-flaked fluid and chipped teeth the first time you put the hammer down on the Hellephant’s 950 ft-lbs of torque.

Silver Sport Transmissions (SST) can get your newfound pachyderm marching down the road with a Tremec 6-speed Magnum transmission package. Kits designed specifically for the Hellephant are in stock and ready to ship for Mopar A, B, and E-bodies.

Front to back, their kit is one of the beefiest and most complete available. A QuickTime SFI scattershield is included to safely enclose SST’s Advanced Friction™ flywheel and Advanced Friction™ dual-disc clutch. Actuating that heavy-duty dual-disc is a hydraulic clutch kit with a Wilwood master cylinder.

The centerpiece, of course, is the Tremec 6-speed with an STX™ short throw shifter. And don’t forget that their PerfectFit™ system means this kit will work with your factory floor console as well. Further back is an SST-designed crossmember that works perfectly with the stock torsion bar crossmember.

A Dynotech driveshaft gets it all to the rear wheels. Other kit components include a new pilot bearing, all of the necessary hardware, and complete instructions with step-by-step photos.

SST also offers pedals, shifter handles, shift boots, trim rings, and shifter knobs as options to complete your install. Be sure to call them at (865) 609-8187 before ordering to make sure you get everything you’ll need to take the leap into the world of four-figure horsepower

    Actually “What standard-shift transmission can handle the power of a Hellephant?” was one of the first questions I bought up in the thread on FBBO about this awesome new mill, and opportunity, brought to us by Ma (now ‘Mama Mia’) Mopar….
    A Lenco was my and a couple of other people’s first thoughts, but they sure take up a LOT of space.
    I’d like to know what/where/how parts and the case itself of this featured transmission are able to handle the power. In other words what components of this transmission are unique to this model for this application, where in the transmission are they located and what are they made of?
    Exciting times! Oh, and HOW MUCH MONEY for this jewel?
