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.

A winner has been chosen for a new set of transmission lines from MDP and Speed Stop Auto Repair

In our traditional fashion of keeping it ridiculous, we entered everyone who participated's name into a spinning wheel, which was then spun until the same person was picked three times. Bryce Pick was our winner.

We'll send you a message shortly and get some details from you so we can have a kit headed your way on Monday!

Thank you to everyone for participating, we'll be doing these from time to time, so pay attention! Video of final drawing in comments for those interested in our method.

01-16 Duramax transmission lines are available for purchase here: https://masonbiltperformance.com/products/speed-stop-x-masonbilt-duramax-transmission-line-kit

11-16 Duramax transmission lines are available and ready to ship with more makes and models in development!

I'm beyond proud of the product we've developed. Built to our lengths and specifications, tested on real trucks, and made in-house by people who care and are willing to back their product.

•DOT approved
•Flame and abrasion-resistant
•Made in USA with a LIFETIME WARRANTY to any owner
•Best customer service around

Our FREE giveaway for a set of these lines ends tomorrow. Get on our page and comment the year of your truck for a chance to win!

R&D is done on the 15-16 transmission line kits!

It’s been a long few months measuring, cutting, and doing it a million more times but skipping a step in quality is not something we are willing to do.

This kit along with any other kit we make in house has a lifetime warranty. That’s right, the infamous “lifetime warranty” so many companies loosely throw around we actually live by it here. If you ever have an issue with a line, a fitting, or you just simply need some help with install, we got you covered on that too.

Dealers please keep an eye out for an email with everything finalized and we can get websites up to date. If you’d like to be a dealer please get a hold of myself or Michael Mason

Here is a list of other dealers below you can contact. Whether you buy from us direct or anyone on this list you will get a lifetime warranty with a real phone number to call for customer service. If you can’t reach our customer service, please get a hold of me. Thank you!
