Review on 🚗 Timbren GMRCK15S Suspension Enhancement System: Boost Your Vehicle's Performance by Jessie Burgos

Very easy to install if you have the right tools. The 2015 model requires a 10mm extension head to remove the factory fenders (which are flimsy and mostly useless) and a 17mm extension head to put in the new ones. I noticed the difference as soon as I rear loaded my 4 wheeler. No more sagging in the back. It must be very helpful when people shine bright headlights on me and think mine are on, when in reality the tail is too low. There are differences when driving. The rear doesn't bounce over bumps yet, so yes, it's a bit rougher, but it's a pickup truck, not a 4x4. I haven't tested it under real load yet, but it should be better. It was.
