    U bolts are zinc and subject to rust and should be at least a low grade stainless The blocks are made from poured cast and arrive showing the grinds uses to clean up the seams. Could of at least painted if not just primered them as they are an eyesore when installed due to factory black finish on everything under the truck except cheap zinc u bolts and nasty looking iron blocks . Function well. But for the purchase amount compared to actual cost of 4 u bolts and 2 iron blocks. Aesthetics need pr

    Nice kit.

    Just enough lift to prevent negative rake when towing/hauling most loads.
