Six bays. Every diesel discipline.

From bolt-ons to full forged builds — and the boring stuff that keeps fleets rolling.

Bolt-ons through full forged builds — power that lasts and parts we stand behind.

Turbo & Fuel

Turbo upgrades, injectors, CP3 swaps, lift pumps — fuel systems that don't lie down.

Transmission Builds

Allison, 4R100, 68RFE, 10R140. Stage 1 daily through competition-grade.

Engine Builds

Head studs, ARP fasteners, fly-cut pistons, full forged bottom ends.

Fleet Maintenance

Scheduled PMs, DOT inspections, service contracts, priority bay access.

Diagnostics & Repair

Drivability, cooling, electrical, hard-fault diagnosis — fixed once, fixed right.
