Win JH's Classic LBZ Duramax 2006 GMC 2500HD + $20K in Cash & Shop Credit

What you're looking at

The headline prize is a 2006 GMC Sierra 2500HD running the 6.6L LBZ Duramax — the engine diesel people actually want. The LBZ was only built for 2006-2007, sitting right before GM bolted on the DPF/emissions hardware of the later LMM. You get the strong pre-emissions bottom end and the highest factory output of the early Duramax run, which is exactly why clean LBZ trucks hold value while everything around them depreciates. Cleetus is calling this one 'JH's Classic LBZ Duramax build,' and it's presented in partnership with JH Diesel & 4x4.

Here's the honest part: the official rules publish almost nothing about the actual truck. No mileage, no horsepower, no transmission, no turbo or build sheet — just '2006 GMC 2500HD Duramax Diesel truck valued at approximately $20,000.' We are deliberately leaving those spec fields blank rather than borrowing numbers from other LBZ builds floating around the internet. Watch Cleetus's build/reveal video for the real combo before you get attached to a dyno figure.

Why it matters

This isn't really a $40,000 truck — it's a $20,000-ish truck wrapped in $20,000 of cash and credit, which changes how you should think about it. The $10,000 check is straightforward. The other $10,000 is a JH Diesel shop credit good toward custom builds, parts, accessories, maintenance and service — genuinely useful if you're going to campaign a diesel, less so if you just want to flip it. For a diesel guy who wants a project plus the budget to actually finish it, that pairing is the appeal. For everyone else, the cash is the prize and the truck is the bonus.

The fine print worth knowing

Read the prize tag carefully: the rules state the truck is 'for RACETRACK USE ONLY; it is not intended for use on open roads and does not meet US standards for street vehicles.' That language matters — it implies a modified or non-titled-for-road build, so don't assume you can register and daily it. The winner must also pick the prize up at a Sponsor-specified location (JH's operation) within 30 days, and there's no stated cash alternative for the vehicle. Entry runs through 11:59:59 PM ET on July 17, 2026, with the drawing on or about July 24 and the winner announced on or before August 14. Paid entries are one per $5 spent in the JH Collection; the free routes — one free online entry per day, or a mailed 3"x5" card worth two entries — carry the same odds and cost nothing. Eligibility is the 48 contiguous states, DC, and Canada outside Quebec, for licensed drivers of legal age. As always: factor the tax bill on a ~$40,000 prize before you start spending the check in your head.
