Review on Optimize Your Vehicle's Performance with Timbren FR1504D Suspension Enhancement System by Richard Surveh

Finished as advertised; However, with standard suspension (no lift) and no cargo in bed or even with a light trailer, the ride gets pretty rough. Not unbearable, but definitely makes the rear end pop when you hit a bumpy road or bump. When I lift my truck I put them back on, but for now I'm doing the back squat instead of the harder ride you get with no load on the truck. To be honest! Towing, bikes in the back - these things hold you in place and provide security as you move down the road. 2014 F-150 FX4 SuperCrew
