Luck of the Irish is a performance diesel shop for the trucks that work and play in central Indiana — tuning, turbos, heads, fuel systems and full builds for Duramax, Cummins and Power Stroke.
The bread and butter of the shop — sourced through our dealer network, priced in the shop, and installed here if you want it done under one roof.
Platforms and custom tuning support for modern and legacy diesels — tow, daily, and performance files matched to your build.

By truck family — ask usParts are half of it. The other half is a bay, a lift, and a guy who answers for the work.
Parts counter and install bay in the same building. The guy who sells it can put it on — and stands behind both.
Everything starts with your truck — year, make, engine. You never get sold a part that doesn't fit what you drive.
We're in Thorntown, we drive what you drive, and you'll see our trucks at the same pulls and on the same roads.
Tell us the truck and what you're after — a part, an install, or a whole build plan. We'll get back with pricing and a slot.
