    file_1.jpg s-l64.jpg bltpancvb.jpg s-l1600.jpg I just installed vern tardel 2 inch lowering shackles on the front of my 40 ford convert. I have weedetr front shock kit and weedetr panhard bar with split wishbones and a stock spring. once I got my car on the road I noticed that my front axle bumpers were smashed dead against my axle. i jacked the front of the car back up and put on jack stands and cut the axle bumpers off as far as I go until I started hitting the metal inside of the bumpers. I took the car out on the highway and no issues but when in town when I hit a dip in the road or go over a bump there is a loud bang. are the shocks bottoming out or are the axle bumpers to short or are the bumpers still too long. thanks in advance rick file_1.jpg s-l64.jpg bltpancvb.jpg

    Establish the extended and compressed lengths of your shocks and then measure the distance at ride height between shock centres. At ride height, the shocks should be 1/3 compressed allowing for extension and compression when driving. It could be they are too long for your lowered application. Do they suit lowered or stock front ends?

    Rick,if it's a loud bang, it's not the shocks. Axle stops are still too long. I did the same thing on my 40, ended up with 1/2" thick urethane ones.

    Sounds like you are hitting the bump stops. I used the 40 ford rear axle stops on my front end. They are much shorter. I am using stock length shackles and a stock type standard eye front spring with with a dropped axle though so I don't even get close to the stops (I think).
