L&D Diesel LLC · North Carolina
Run it
harder.
Built for the L5P.
We build it, weld it, and bolt it in our own bay in North Carolina. EGR kits, downpipe-back exhaust, and hardware for 2017+ Duramax trucks — the stuff on this site is on our own trucks.

// From the Bay
Real Trucks, Real Work



// Straight from the Shop
Builds, reels,
and shop days.
Every truck that rolls through the bay ends up on our Facebook — teardowns, welds, dyno pulls, and the occasional cold start. It's the fastest way to see what we actually do.
// The Code
Shop-built.
Truck-proven.
We're a small North Carolina shop that got tired of babying failure-prone factory parts. Every kit we sell gets built, bolted on, and beat on in our own trucks before it ships in yours.
