Review on 🔧 Upgrade Your Rear Axle with the Timbren Suspension Enhancement System by David Boone

3 month review, 2018 F150 (4-5k trailer closed daily) I pull a trailer daily and wanted to wait a few months before writing a review . So. First, the installation is annoying. I didn't remove the tires and had to lift the back of the truck to get clearance. What made it so difficult was just trying to get a bolt through the frame. Once it started it was cake. All I had was a deep socket and the bolt kept trying to fall out...just a pain. It's hard to explain until you do. The ride on them is very springy even though my trailer is very heavy. My trailer easily dropped my truck 3-4 inches when there was nothing on the bed. So I got them, threw away the tiles and other bathroom stuff, my truck really sank. If there is nothing in my bed, the journey will be very happy! unbearable. If I have a tear in my bed, say 1000 pounds more, the journey is good. According to the instructions I had to add a spacer, I have 18 F150 to get the right amount of clearance there is empty. So it's not a problem. In short, I would recommend them if I'm really torn between 3-4 stars. i am in a love hate relationship It's quite expensive for 2 pieces of rubber and a mount. But I don't trust airbags and I don't want to pay $600+ for them. I feel like I'm getting used to the rebound and those things really take the pressure off me.
