Our Pro LSX Kits are built for people who want their swap to run the first time, not spend more money replacing parts that wont work. Just because it fits doesn't mean its the right part. Don't tune around issues. Do it right the first time.

Whether you're dropping an LS into a classic car or building a street monster, our kits eliminate the guesswork.

No mismatched parts. No fuel leaks. No throttle issues. Just proven combos that work — tested in real builds by the same person who tunes and builds them.

Tuning should be the final step — but it rarely is.

Most swaps we tune reveal issues that should’ve been caught earlier: exhaust leaks, fuel pressure problems, wrong injectors, bad wiring, and more. That’s when customers end up spending double — chasing parts, replacing mistakes, and wasting time.

These kits are built to prevent that.

Clean installs. Reliable performance.

This is how LS swaps should be done.
