Skydiving, H3 Hummer, & WordPress


  • I’m excited to announce that 2nd Generation H3 Hummer Rock Sliders are nearly in production. The goal has been to improve upon the design while addressing issues. The most important issue being addressed is bringing down the cost of shipping. I also wanted a modular design to be able to implement new features. Even so…

  • Earlier this year, I started having issues with the keyless entry. The distance at which the remote worked kept reducing week by week. I also had the Tire Pressure Monitoring System (TPMS) light turn on, despite having replaced all of them with brand-new ones. I didn’t realize the two issues were related and started by…

  • I like to think that every challenge is just an opportunity to improve and move to a better position. I’ve parted ways with the company that produced all of the H3 Hummer parts for the last 10+ years. However, I look at this as an opportunity to finally reach some goals I’ve wanted for a…

  • Broken Header Bolts


    Years ago I permanently fixed an exhaust leak on my GM equipped LH8 5.3 V8 Alpha H3 Hummer and I think everyone with an LS engine should know about the ARP Chromoly Header Bolt Kit. However, those ARP bolts alone won’t completely fix the annoying sound of an exhaust leak. If the problem is anything…

  • The website was down


    I’ll start by saying that don’t have plans to stop doing whatever it is that I’m doing here on Schwarttzy.com any time soon. I’m still selling the off-road parts for the H3 Hummer. I’m working on a huge update for the WordPress Theme – Adventure that is taking me forever to finish. Then there is…

  • Custom H3 Hummer prototypes take a lot of time to design develop. Which is why it always so exciting to announce and share when progress has been made. Today, the last major obstacle in the design phase of the Hi-Lift, CB Antenna, and Bottle Opener mount has been cleared. The parts bolt up, although a…

  • An important Off-Road accessory for all solid axle-equipped off-road vehicles is the heavy-duty differential cover. The HD Diff Cover protects the Ring & Pinion from damage where one of the tightest tolerance torque maneuvers happens. The Ring & Pinion is where the engine’s torque gets turn 90-degree to drive the axle shafts. With the precision…

Being a fan of nearly all things automotive, I watch TFL’s YouTube Channels quite regularly for their reviews, adventures, and opinions on all types of vehicles. This video was…

  • Purchase the Rockford Fosgate Punch speakers P1675-S and P1675 for the H3 & H3T Hummer to get the best combination of an inexpensive price and improved sound quality. For the H3 Hummers with the Monsoon Sound System, purchase the Rockford Fosgate P3SD2-8 to replace the factory dual coil 8-inch subwoofer. Also, 2 packs of the…

  • The 2008 Alpha H3 Hummer #WarWagon needed the upper control arm replaced because of a failing ball joint on the passenger side. Prior to shooting this video, I’d already replaced the control arm on the passenger side. When an arm gets replaced the other should be replaced too. The reason to replace both is that…

  • Engine Oil Analysis


    In Fort Wayne, Indiana the company called Blackstone Laboratories tests the oil from customer’s engines to provide “easy-to-use, understandable, and accurate oil analysis.” Recently, I sent in a sample of oil from my Alpha H3 Hummer 5.3L V-8 engine to check on the condition of the engine. The #WarWagon has over 200,000 miles on the…
