: Extended rear bump stops?

Does anyone make extended bump stops for our rear ends (the ones at the spring perches?)

My 4" driveline is lightly kissing the floor if I go over a large bump at a decent speed (such as taking an intersection with a tall crown at about 45-50mph). It just taps the floor a bit. I'd like to put some slightly extended bump stops on spring perches of the rear axle to "help out" when the rear end sees a sudden, large upwards movement. The car takes large bumps under individual tires OK, but when both tires hit a large rise the driveline sometimes taps the floor. This becomes a larger problem when I have multiple people in the car or in the backseat.

I noticed that in this month's Hot Rod when they cover the silver/red year one Chevelle they built extended bump stops for exactly this reason. Is there something off the shelf I can use? If I have to, I'll weld up my own steel extender brackets for the stockers, but I'd prefer a larger rubber bump stop as the larger mass of rubber will have a nice "cushioning" effect.

Troy,

I think that the majority of El Camino's and station wagons had brackets that bolted to the existing bumper mount and raised them about an inch. I have them on my El Camino.

dave is correct. it was only an elky and wagon thing. the reason is because they had thicker coil springs and the higher stopper would bottom befor the spring touches coil to coil. but i dont think they are being sold anywhere. you will need to find used ones.

My GTO had them as well. As far as I know the rear end was replaced. I still have them mounted and I have never bottomed it out. Then again I probably have stiffer springs.

I also have the Elky extenders on my '72. But I used a set of Energy Suspension bump stops for extra protection. I currently am using part number 9101, they are 2 5/8 inchs tall. The 9103 are 1 5/8 inches tall. If I rememeber correctly the stock bump stops are only about an inch tall. Also you could cut down the Energy Suspension stops to your needed height.

Excellent. I'll pick up a set of the extenders. I was not aware the Elky's and Wagons came with these from the factory. I like it when a factory part exists that will fix my problem. smile.gif

I could probably accomplish the same thing by removing my subwoofer box and 2 amps, but... nah. tongue.gif

Thanks for the pics. I managed to pick up a set today.

Unfortunately as of today my car is out of action for a while... lunched a distributor gear last night. Time to yank the motor and tear it down for an inspection. Probably needs it too after a whopping 2500 miles... :mad:
