It was a great day to be out at Cordova Dragway for Day 3 of Hot Rod Magazine Drag Week. The rain held off, and it was an awesome opportunity to connect with racers, race fans and colleagues in the industry.

This has been a year of many firsts. This was really our first experience with a full vendor setup on display, and we're extremely grateful for the engagement and interest we saw yesterday. From loyal customers showing love and appreciation, to people who had never even heard of us but were thoroughly impressed with the difference and quality of our products. We can't wait to get out and do even more.

Where should we go next?? Drop your favorite upcoming race events in the comments and let us know where you'd like to see us.

This Massey Ferguson 8470 was condemned because replacement wiring harnesses were discontinued… so we fixed that.

Tired of injector harnesses that don’t fit? 😤
