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.

If you have served our country in any sort of form of fashion, we at Speed Stop would like to say thank you. No matter the contribution I couldn’t operate my normal life and enjoy my family with you folks.

Happy Memorial Day to all. If you are a member of the service shoot me a message and maybe I’ll just splurge for a sale. Again I couldn’t do a sale or any of this without the folks who made this possible.

Thank you

The best part of manufacturing products in house is catching things like this. To the naked eye you probably can’t identify the failure.

Every single line is cut and double measured, crimped fittings are double checked off the parts list, bagged fittings get used to an example we have, yes we have example fitting bags for each year we provide because I am a human. Do I have most memorized? Absolutely but, we like to double insure our quality here.

If anyone outside of our manufacturing process can identify where the failure is here I’ll provide you a free set of lines. If you don’t have a truck that meets that requirement I will give you a credit to the website for the equivalent amount of the year truck you have.

If you want a free set of lines, you have to read till here. Thanks for coming to my ted talk.

Yesterday I had the chance to buzz down to Randy's Transmissions take a small tour of the facility with Matthew Moore and also pick up our order of Fluidyne coolers.

Coolers will be up on the site before the day is over, we are also working on line kit and cooler packages to save you folks a few bucks who want the package deal.

We also have a few other things in the works so please keep an eye out.

I also wanted to remind everyone our line kits come with a lifetime warranty, while you’re reminded of that, these Fluidyne coolers also come with the same. We are striving to bring the best products and service we can to you guys!

Sometimes the smallest fish in the ocean find the sharks, thankfully this time we got to work together.

Speed Stop Auto Repair/Masonbilt Diesel Performance meets Randy's Transmissions and Fluidyne Coolers.

We just placed a cooler order for 01-16 GM trucks, but had to include a 17-19 so R&D is coming for that.

If you’d like to order a line kit along with a cooler, you’ll now get a discount on that!

We have tons of line kits available to ship from east to west coast, next week we will have coolers in hand.

Contact myself or one of our dealers!

Please give us until Monday to get all the websites updated for line/cooler kits.

Absolutely wishing we could be here for this one, but some of the finest folks out of our corner will be in the flesh! Trans lines, front end parts, free swag, maybe a give away or so. Did anyone mention the stellar customer service or no bs lifetime warranty?

Catch us there 🥸

3 days.

At this point, you either already planned for it… or you’re about to regret not going.😏
