    1999 Tahoe
    I bought these to replace the missing ones on my Tahoe, they were very easy to install and look very nice.

    Good
    It is about 1/2"- 3/4" longer than stock bump stops. So if your car is lowered you will be bottoming out even more. But I don't have an issue. I have the slp Bilstein shock/spring kit. And I haven't bottomed out yet.

    Fits Perfect
    Fits perfectly as it should, although it did come with 2 bump stops per package not 1 like it says.

    Arrived Sooner Than Expected and Fits My Dodge Coronet 8.75 Rear End Great!!!
    This u-bolt kit works great on a 1968 Dodge Coronet Superbee with a 8.75 rear end. Just might want to trim the ends after installation but I left mine as is.

    Did The Job
    The U-Bolts worked well. I torqued them in stages to avoid possibly stripping them, like I had read about in other reviews. I would buy them again. (Unless they fail in the future, of course)

    Keep It on the Road.
    I am sure these brackets will out last the truck. They appear to be made of thicker gauge metal, powder coating should prevent rust for many years. I did my repairs on my driveway with the truck up on jack stands. I used an electric drill ($8 yard sale) to remove the old rivet heads and a angel grinder ($14 Harbor Freight) to grind them flush before driving them out of the chassis. This took a hour or so for each. The rubber bushings are high quality the metal sleeves are heavier than original and took no damage while being driven into the spring eye (tip: clean the inside bore of the spring eye to bare metal before you attemp to press or drive the new bushing in). The bracket fitted up nicely to the frame holes lined up well and the nuts were deformed on the last thread only, so only moderately increased the difficulty in tightening. The shackle bolts on the other hand the whole nut had been ovaled so much I had difficulty getting a socket over them and tightening them with a 18 inch long 1/2 drive ratchet and a 18 inch long box end took what seemed and eternity as I had to exert maximum effort for every 1/16 to turn this left me with very sore hands.
