I posted about my Daystar Stinger bushings on the Truckhaven 2018 thread. They work great for me as they limit the suspension while crawling, but allow a little more compression upon hard hits while moving faster. Would not work well for racing applications because I don't think they would hold up. On the Truckhaven trip, the driver side bump's shaft unscrewed itself and was lost to the desert. I called Daystar and they eventually agreed to warranty the lost items. Shipped superfast, since I received a box from them today. Unfortunately, they sent the wrong parts. I received the shaft and an end cap, not the external bump that went missing with the shaft. A quick phone call, and they are now sending me the correct part, I hope. The customer service dude almost sent me a complete bump, but then located the single part I needed. Said I could keep the end cap for a spare. After a few conversations with TDavis about my failing power steering pump, I decided to add a cooler. I ordered a nice little plate cooler today. I will go into more detail when all parts arrive and I do the install.
