I figured as much.

Of course, you could put that thing IN your truck, drive to the track, and do some serious damage.

What did you wind up doing with your pinion angle issue?

 

I found out that Hotchkis makes a upper/lower control arm kit for the purpose of pushing the axle back on an Impala SS. The lower control arm from that kit just happened to be 1/2" longer than mine, and bolted right up. End result? I went from a 7* angle on the pinion to 3*. This, compared to the 4* I have on the tranny output shaft, equates to a 1* negative difference, which is perfect for torque delivered under acceleration. And the vibration is gone.

 

Cool. One less thing to worry about.

 

Agreed.

Hey - how's your shift kit running? I'm getting ready to put mine in, together with upgraded servos, better separator plate, aluminum accumulator pistons, deeper tranny pan, etc.

 

On mom's suburban the bilsteins rode way to stiff. We switched the fronts to edelbrock IAS and now the suspension actually feels like it is working on the smoother stuff. Once potholes and whatnot come around they stiffen up. They do work as advertised, although I doubt that is what you are going for.

What about some adjustable Rancho's for your truck?

 

Thanks, I've heard that the Ranchos need to be turned up all the way to '9' to get close to what the Bilstein has to offer...leaving no room for adjustment...but I'm not sure. Perhaps I should just try them.

Bilstein is actually here in SoCal, about 30 minutes away, so I may just hit them up for revalving. Has anyone ever had this done?

 

try turning up your torsion bars first.

 

There are two reasons why I think this is not an option...one, the driver's side screw has no threads left in it, and two, I've heard that although cranking up the torsions results in a stiffer ride, it also results in more bounciness.

The phenomenon I am trying to correct is dampening after hitting a bump (like on an off-ramp or on-ramp) - it already bounces more than I want, I need it to bounce less.

 

I don't think you'll get what you want out of an off the shelf shock.

Get em revalved for your spring rate.

I would have also chosen linear rate springs over progressive ones ala Eibach. But I guess it depends on what you want to accomplish.

 

have you looked into QA1's?
