We are a company based out of Pflugerville, TX where we specialize in custom built, third generation HEMI stroker motors and top of the line performance parts and accessories for late model Chrysler/Dodge/Jeep/Ram Hemi cars and trucks.  We strive to offer the highest quality performance parts, tuning and the best customer service you'll find anywhere!

Did you know that Inertia Motorsports was the builder of the first 372, 383, 392 and 407 5.7L HEMI based engines and the 2nd 426 6.1L based HEMI engine in existence?

We are also engine builder for the four fastest naturally aspirated HEMI Trucks in the Country.  Including the fastest trap speed HEMI Truck, fastest trap speed HEMI LX, fastest standing mile HEMI LX, fastest 5.7 based naturally aspirated stroker LX AND the fastest 5.7 based BIG POWER ADDER LX IN THE WORLD!!. That's Wilson Gautama's car you see in the picture at the top of this page.

In 2013 we built a 6.1 based 392 stroker motor for NFL superstar Larry Fitzgerald for his old school Mopar.

We are here to serve you, so please give us a call or send us an email (or contact us via Facebook or Twitter) and we'll be more than happy to help with anything we can. We hope to hear from you and thanks for visiting!

5.7L "EAGLE" VVT Camshafts and Cylinder Heads!

We are proud to be the first company in the world to develop custom ground new camshafts and performance cylinder heads for the  2009+ 5.7L "Eagle" HEMI. In fact we still supply cams to other Hemi vendors but we were first on the market.

These camshafts produce excellent low to mid range torque/power and will work with MDS while remaining easily tunable.  We also have NEW CORES for these cams which means we can run higher lift and more aggressive ramp rates for even bigger gains from our camshaft offerings. Check all the options on the camshaft page and on the webstore.

We also have CNC ported 2009+ 5.7 heads available.  These are available in two versions with stock combustion chamber and with big chamber.  The CNC ported 09 heads feature full porting and hand blending, along with our proprietary valve job.  Additional features include deburing of sharp edges, and a directional vein for increased performance at high valve lifts.

This is a 1993 Toyota Supra with a Hemi stroker power plant! On top, it has a Kenne Bell supercharger!  

This is an amazing build by TeamDriftPower in Sweden. The really cool thing about this car is that Inertia Motorsports provided the balanced rotating assembly for the 6.1 based Hemi engine, as well as the camshaft, oil pan and a billion smaller parts to make it all work. It's a 400 cubic inch engine with a Kenne Bell supercharger. Carillo rods and custom CP pistons. The above is the first video. They're now fine-tuning the car and working on getting some additional upgrades so they can turn up the boost and start running it at competitions. We are working with driver and Team Chief Leif Häuselmann on the build and he and Stu have worked together for a long time now to get it all together. Hope you enjoy!

Have questions about any of the packages listed below, or looking for something a little more custom, such as a motor built for nitrous or a supercharger?
