Edelbrock was reluctant to put much of anything into writing. Their suspension/shock absorber expert said that it appeared that his predecessor, who developed the IAS shock for their 4" lowered sales, may have tested it on a truck that had extenders.

The bottom line is simple. A stock shock is 16" compressed. The Edelbrock 34023, which is recommmended for a 4" drop, is almost that long. I didn't get an accurate measurement as it was difficult to compress and I have since sent it back, but it was very close to 16" compressed. This means that most of the room for compression, as in after going over a bump, is already used up just in mounting the shock.

A truck with a 4" drop would seem to need a shock that is approximtely 4" shorter or else use a shock mount extender that would allow for adequate compression to dampen a shock/bump.

Thanks. I didn't see that.

 

So what the hell did I pay $75/piece for these drop shocks? Did they say they were going to redesign these things?

 

I don't think they'll redesign them. They've been selling plenty of them since 1999 and making their $$.

 

Here's the reply I got from them.
"Our shocks are designed to be used with a lowering kit that relocates the shock mounts so you can get more travel out of the shock."

Maybe that caviot should be put on their description.

Shock extenders should be used on drops 4" and lower regardless of shock size, the extender does what Edelbrock said, It give you more travel, also changes shock angle....I had Belltech tell me this 10 years ago and have used them ever since.
