What's the one truck you wish you'd never sold?

You know the one.

The truck you still think about every time you see one go by.

Drop it in the comments.

This weekend we remember and honor the men and women who gave everything in service to this country.

Freedom was paid for by people who never made it home.

From all of us at Moonlight Diesel, thank you to those who served and to the families who continue to carry that sacrifice.

Moonlight Diesel will be closed Monday in observance of Memorial Day and will return to regular business hours on Tuesday.

Happy Mother’s Day from Moonlight Diesel!
Today we celebrate the women who keep everything running strong. Both at home and on the road. Whether you're hauling, wrenching, or raising the next generation, your strength doesn’t go unnoticed.
To all the hardworking moms out there, we appreciate everything you do.

A Great Run Comes to a Close — But There's Still Time

To our loyal customers and towing community,

We’re officially announcing the retirement of the Hercu-Sleeve Hitch Adapter — a product that redefined what a hitch sleeve could be.

Built from high-tech polymer, the Hercu-Sleeve delivered a quieter, tighter, and corrosion-resistant towing experience. Its interlocking design and one-piece simplicity made it a favorite among truck owners tired of the clunky, noisy alternatives.

However, with Ford discontinuing the 3" hitch receiver, the demand for our 3" to 2" Hercu-Sleeve II has naturally declined. As a result, we’ve made the decision to discontinue production of this model.

Snow’s hitting Moonlight Diesel today.

Cold enough to find every weak battery, every lazy glow plug, every fuel system that’s been “mostly fine.”

Winter doesn’t care about excuses and it looks like we still have some to look forward to.

If your truck’s acting soft in this weather, bring it in. We’ll get it right and get you back on the road where you belong.

There’s a reason S&B cold air intakes have the reputation they do.

Better airflow.
Cleaner filtration.
Quicker throttle response.
A diesel that just feels less choked and more alive.

You bolt one on and the truck breathes the way it always should have. Less strain. Better efficiency. Smoother pulls under load. It’s one of those upgrades you feel every time you roll into the throttle.

Now the part nobody likes.

After five years with no increases, S&B pricing is officially changing.
The new pricing takes effect Friday, January 30 at 5:00 PM PST.

After that moment:
• Orders ship at the new price
• Waiting officially costs more

No loopholes. No grace period. Once the deadline passes, it’s just the new reality.

If an S&B intake has been on your list, this is the quiet moment before the door closes.

Message us or call the shop if you want current pricing locked in before the clock runs out.

As 2025 comes to a close, we want to say thank you to everyone who trusted Moonlight Diesel with their trucks this year.

We don’t pretend every job is easy or every problem obvious. Some fixes are quick and straightforward others take time, patience, and a few extra phone calls. Either way, we take pride in doing the work and standing behind it.

Thank you for your business and your trust.
Wishing you the very best in the year ahead.

Christmas tree’s up in the shop.
Now the real question…

What do you want under your tree?
Because rattles, leaks, squeals, and “it should be fine” don’t fix themselves.
