Review Product
Works as Advertised...Overall happy
Kit is clean and easy to install....just a couple notes would be: 1. The Setup nylon spacer bolt they send with kit was too short to use for mock setup 2. I had to reverse the top mount and it just so happened that one of the mounting holes lined up with a factory hole in the frame. Used to pull 5,000lb boat trailer and leveled out nicely! NIce product for lowered truck applications and fairly priced.

Second time using this lowing kit. Real nice kit.
Did a rear axle flip kit from Bellteck. Some brackets on the axle got in the way of the air bag on the leaf springs. Would be hard to drill frame of truck with gas tank,exhaust in the way. Mounted air bag on top of axle with my own lower bracket for the air bags. Used upper bracket that came with air bag kit. Came out great, looks like a factory installation. Will use again in future.
