Welcome to Overkill Motorsports. Overkill is about V6 Tuning and Performance Parts, specializing in the GM 3.6 Engine Family including LFX, LGX, LLT Direct Injection and LY7, GM 3800 Supercharged L67 V6 for over 14 years, and Chrysler's 2011+ Pentastar 3.6 V6, as well as other V6 engines found in your GM W-Body and more! Not a do-all tuning shop, Overkill aims to be the best for these vehicles. Remember it's not just a V6, not if it's Overkilled!
