EDIT. Website is back to, categories may be wonky for now. Hopefully by Monday we are fully back up to par!

Good afternoon everyone.

Today is the day. The website is already currently down going under the knife.

We are hoping to have it back up before the day is over. There also may be some odd times this weekend there will be no access either.

If anyone needs parts or support here is three ways to reach myself or for any tech support for transmission lines please call one of the numbers.

Thank you.

Exciting things happening in our universe. Before you ask— Yes, they’re better overall. Yes, they have a real warranty they actually back. Yes, the design makes more sense. Yes, we’re happy to ship to you.

Sheeeessshhhhhhh the bad Larry’s have finally landed.

Axiom Supply absolutely dropped the mic with these UCA’s.

Box design, laser welded, no welded perch in the middle for the ball joint. The perch is now built into the lower portion of the arm itself making it a much stronger design than anything we’ve seen. Fully serviceable and of course the one and only No Bu****it lifetime warranty.

We decided to pair these arms with a set of Fox HTO Performance Elites, and Fox HTO 2.5’s on the rear. Yes they look good, but the comfort of the new ride is way nice.

11-19 and 20 + are in stock ready to ship! 01-10 we are unfortunately a little ways out but going as fast as we can.

With this all being said, the website is going under a ginormous facelift. I will make another post tomorrow about the specifics of it. As of right now if you’d like a set of control arms they are on the site, in stock, free shipping and, who knows, leave your shirt size in the comment section and you just may end up with some free swag.

We got a fresh shipment from Bosch! Injectors, pumps, and some other odds and ends.

Pricing is as follows:

•2x set of LBZ reman units $3,800 shipped NO CORE CHARGE
•1x set of LML NEW $3,040 shipped
•3x LBZ/LMM reman CP3 pump $975 shipped NO CORE CHARGE

Send us a message if you are interested or need a package deal for your project!

It’s been a hell of a first year.

As of Monday, I’ve been able to make this my full-time job, and I couldn’t have hoped for more adventure in our first year.

I’ll try to keep this short and sweet:
Thank you to everyone who has genuinely supported us. None of what we’ve accomplished over the last year would have been possible without you.

Our vision is still the same as when we started, but even more simplified: sell products we know are good, offer the best customer support on the market, and stand behind everything we sell 100%.

We do no service anymore, but will pick up the phone whenever you have a question about a product or installation. Anything we produce or have in development has a lifetime warranty- to any owner, because we know it’s the best product on the market and the you shouldn’t have to take accountablility for a manufacturer’s shortcomings.

We’ve broken down what we want to be as a company into two words that have guided us through life for the past few years: “Be better.”

At the heart of everything we do is the goal to be better- better than the competition, better than yesterday, and better than we are right now.

Of everyone that could’ve looked the other way, we especially thank:

Speed Stop Auto Repair
UnderDog Diesel LLC
Axiom Supply
Diesel Addiction

And most of all, everyone on the Masonbilt Performance team who helps keep me sane behind the scenes.

Thank you for an amazing first year and many more to come!

Rudy's Spring Jam 2026 Recap!

This is easily one of the highlights of our year and we were beyond excited to have the opportunity to participate as a vendor this year!

Between showing off our new parts, seeing old friends and making new ones, we learned a lot and had the opportunity to reflect on the future of our company.

With that said, we have some exciting big things coming over the next couple months and products teased at the event coming to the market.

Massive thank you to Axiom Supply and Rudy's Performance Parts for making this possible!

We'll be back again next year; this time with more parts, more stickers, more chaos, and race truck.

We are now a dealer for Hot Shot's Secret. Producing the best fuel and oil additives in the industry, and having used these products for years, we now stock their complete lineup for both racing and stock gas and diesel applications. All products will be available for purchase on our website and pick-up at our new location. Send us a message if you need help determining what product best suits your needs.
