A small testament to the strength and importance of making a quality part.

Customer reached out yesterday thanking us for supplying a quality pin and bushing. His son was in a wreck and there is no doubt because everything stayed together that his door was able to stay on the truck and not causing the other vehicle to enter the cab.

Our 88-98 heavy duty bronze door bushings are the toughest on the market!

We often get ask what the difference is and its pretty simple. Material and machine tolerances.

We make everything in house and keep a close eye on QC. Our pin to bushing tolerances stay within .003-.005 of clearance. While others are .020+. While that may not sound big it makes a huge difference by the time you get to the end of these long doors.

We sell standard and oversize for those who let it go to long.

Our rollers are also a nice design with the fact they bolt in. Removing the stock one can be a little tough, but its well worth it when they are broke off and banging and popping.

Our billet glove box button is such a simple and easy swap for something to make a big appearance difference.

Only needing 2 tools, short phillips screwdriver and a short 9/64 allen wrench. 5 minute swap easily.

Offered in raw machined (pictured) or black anodized.

PS yes I cleaned the dash off after removing the factory one so no one jumps me for dirt! 👀👀

Such a simple 2 minute upgrade that makes a huge visual difference!

These billet HVAC k***s are beautiful. Offered in black anodized too if thats the look you want. Simply pop the old off (make sure the metal clip comes with the stock k**b thats inside it) and press the new one.

The headlight k**b is also just as simple and beautiful!!

Probably still a favorite funny video on our door bushings here.

Our bushings are machined with tighter tolerances, far superior material, and with a failure rate of zero they are a no brainer! Offered with the option of with or without pins. Our pins are machined from 303 stainless and use E clips to hold in place. Paired with a set of our rollers it makes the door opening and closing just like factory. Snag a set today this new machine is fully in action making it happen!

Now that we have had one in the wild for testing a bit it's almost time to post these on the page! Nice billet hood release catch. This is the first version so minor changes have been made for aestheics, but will function the same.

Will come with some nice stainless hardware. Should fit roughly 81-98 GM trucks. A small note about these. They are going to have some scuffs over time due to the nature of how they work (being jammed in and out of the radiator support). But as shown its all in 1 area and really not to bad at all!
