I’d probably say the shackles are thicker and fit better than the lippert brand. Fit perfectly and great value for the money. Too no time to put them on vs the flimsy stock shackles from factory. Grease fitting work and do what they’re supposed to do. Would buy again!

This product is made well and heavy duty.The only problem I see with this setup is the bolts that goes through the hanger on my trailer is 3/8 thick.The bolts has the kneeling at the head of bolt to grip the inside hole of the hanger.The problem is the kneeling part is to long and it wouldn't allow the bolt to go all the way through the bushing of the spring.The bolts are actually made for the heary straps that was included in the kit.

These installed well on my tandem axle fifth wheel. My first impression is they should last a long time.

Everything you need in the kit.Only issue I encountered was the need to file back the knurling on some of the pins otherwise they will bind to the bush which would inhibit movement.
