About Us

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 available 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? It's true.

We look forward to helping you making your car go faster!
