DX is Lethal Performance's in-house hardware line — fuel delivery, carbon fiber, and suspension developed by the same crew that builds and races our own cars. Every DX part started as something we needed for a build in this shop and couldn't buy.
Every DX part is developed by Lethal Performance's in-house team, tested on our own cars, and supported by the same techs who fuel our builds. You're not buying a rebranded catalog part — you're buying the thing we built because it didn't exist.
Return-style fuel systems that scale from 600 hp street cars to 2,000+ hp monsters — proven under some of the fastest Mustangs in the game.
No overlays, no gaps. Precision-fit carbon fiber for Mustang and F-150 platforms that installs like OEM; like a factory option Ford never offered.
Explorer ST-specific kits that cut the wheel gap, kill the float, and keep the ride quality your daily still needs. SUV stance, sport-sedan manners.
