    Fixed all my problems. Parts seem of good quality.: Needed new equalizers on a 16k equipment trailer…everyone wanted 250 to 300 online, locally it was a 5 day wait at 325. For that price it’s was wiser to replace all of it at this price. My only wish was that the actual spring hanger bolts had grease fittings but was presently surprised that at this proce point t the equalizer bolt was greasable (the original reason the replaced equalizers failed was no grease). I’ve installed but have not towed; can only imagine the improved ride quality and I won’t miss the excessive tire wear on the right side.
