I'm going to upgrade over the winter to double adjustable rear shocks.

I currently have the Calvert/Rancho 9 way single adjustable.

Looking at Afco, Viking and Jegs price point of shocks.

This is for the street/strip 330 with Cal-Tracs and 275 drag radials.

We welded on a new upper mount to get the shocks more vertical so it made the shock requirement shorter.

My questions are:

1. Which is the best shock for my application?

2. Since it's not a stock length, do I measure for length with the car at ride height and then full extension?

3. Do they only come with the spherical rod end mounting and are there any issues with that?
