Hummin’ Cummins 1989 Vintage Kid’s T-Shirt




While it began life as an agricultural engine, its popularity picked up immensely once it was put into Dodge pickup trucks in 1989 and its industrial roots really began to shine. A simple design with unmatched reliability, tremendous performance potential, and rugged, million-mile durability sums up the appeal of the 12-valve 5.9L Cummins 6BT diesel engine. The 12-valve 5.9L 6BT came out of the box with a conservative 230hp, 440 lb-ft of torque, and a P7100 inline injection pump, but was easily capable of making more than twice that with minimal modifications using just basic hand tools. Going deeper into mods and engine tuning could push these 1,100 lbs. cast iron powerplants to 1000+ horsepower that would eventually cause the stock heavy-duty powertrain behind it to eventually implode without appropriate upgrades. Regardless of what you drive, if you’ve got a 12-valve 5.9L Cummins 6BT under the hood, you can expect it to keep hummin’ along for the long run.


Like all our designs, this one is treated with our signature ‘relic-ing’ process which includes our own secret recipe of hand-painted chipping, cracking, fading, and just the right touch of yellowing to ensure that it looks the part of a true vintage imprint.** We lay these works of art down on premium Gildan 5000B tees, one of the best-wearing kid’s t-shirts available today, via state of the art direct to garment (DTG) printing which allows us to create a vintage effect that simply can’t be accomplished with other printing methods. In short, this youth pro weight tee is perfect for every kid who wants a comfortable shirt to play, relax, or romp around in and our durable, high-quality prints will survive many adventures.

Not sure what size is your best fit? We recommend taking one of your current t-shirts, laying it flat and measuring it. The measurements in the chart below are taken with the shirt laying on a flat surface. To get the length, measure from the high shoulder point down to the bottom of the shirt. To get the width, measure approximately 1-inch below the armhole, across the chest, from seam to seam. While our tees are all made using premium, pre-shrunk, ring-spun cotton, there can be some shrinkage depending on your personal wash and dry cycles. With that said, if you’re on the fence, we always suggest going up a size.
