with chris' comments, add columns for 'requirements' - i.e. - retain stock springs, custom mounting hardware, and 'comments/notes'

 

The Penske's are approx $3200 and are available from Ankeny Racing Enterprises (www.ankenyracing.com). They are either single (rebound), double (rebound & compression), or triple (slow rebound, fast rebound, compression) adjustable. The are threaded body shocks for use with adjustable spring perches.

Here is the shock dyno chart for the Penske double adjustable shocks as revalved for autox use by ARE.

 

Is there an update to this data?

 

Yes, lots of new data in the past two and a half years since this thread was last touched All in the many, many, other UTH threads you may find here in UTH and racing & competition...

 

Thats an interesting a rather strange shock graph.

First, that is a very digressive compression curve

Second, there is a lot more compression than rebound.

Third, from the specs it looks like it is Penske's linear/digressive mixed piston, with the linear site on rebound. I've always thought that went the other way around to allow digressive rebound for soft spring/big bar stock car setups.

Fourth, there appear to be two settings. Are we looking at different front/rear, or 4 shocks the same with different external adjustments?
