WHEN considering a lowering kit for your 1988-199 C1500 or (OBS GM Truck), you’ll find there are quite a few options out there. Most companies offer parts individually, so you can get creative with parts combinations in order to get your desired results. In our case, we wanted to try and get this job done with performance and ultimate ride quality in mind. Being that Belltech Suspension was a huge part of the sport truck movement back in the ’90s, the company knows a thing or two about OBS GM trucks. With that said, naturally they were our first call when we decided to tackle the suspension on our 1990 C1500.
