I know they sell shocks with springs around them and possibly the springs only to install around the shocks to give the shock more support but that would be for the rear shocks
I had those on my car at one time in the past and they worked well
Not sure about travel length myself
I do know that Jason is using a gas shock made by Gabriel in his 64 as best I can recall which I think is an upgrade to the stock original shocks
I can only comment on one aftermarket shock, the Gabriel gas cushioned shocks, so I really have zero comparison to anything else. I assumed way back since it seemed to be the recommended shock that it would give a ride similar to original gas cushioned shocks, but I wasn't born until Dec 1964 so I was too young to even know what "stock" performance was like. Here is the dealer data book info n the original shock:
And, of course tired worn coil springs vs new regular coil springs, vs new heavy duty coil springs (what I run) will make a lot of difference in terms of smoothness and stiffness of ride and the ability to support weight (i.e. rear passengers and dead bodies in the trunk).
