[Fot] Lever arm shocks vs. tube shock conversion

[fubog1]

 The valves used to be available in several different specs, yes I think the main difference is in the springs, and maybe port sizes, as I recall.I actually have a set stashed somewhere but I forgot where, which I may find someday by accident when I'm looking for something else that I forgot where I put...

When I got my TR4A it had sat for decades.  One of the rear shocks leaked badly and I decided to tear it down and have a look.  It had stiffer versions of the little springs, if I recall they were blue instead of gold.  I got curious and looked at a couple of other set of old "racing" lever shocks I had acquired and found that one racer had soldered the standard spring into a tighter coil, maybe with a little wasjer to stiffen the rebound a  little.  I only had one of those shocked so I copied that and made a pair. They worked just fine.

 I've always felt that was a lot of $$ & effort for what gains???There's nothing wrong with the standard lever-action design, and Apple Hydraulics will do a 10% stiffer if you want.It's hard to evaluate a shock by the push/pull method since they have a high & low speed function, and you can't feel the high speed by working it by hand.A tube shock conversion does make sense on an all-out spec racecar because they've developed them to a point where the ability to adjust the rate & proportioning is almost infinite.Most vintage racers/racecars don't fall into that category, and some groups still have vintage rules (I think )Besides the ability for limited adjustment on some, which is a big plus, I don't see the benefits for most vintage applications, nor street cars.Now having said/typed that, this is just my personal opinion, many folks use them, and I'm sure will chime in with their thoughts...

Hi all,
I am new to the FOS list. I own a 1967 TR4A-IRS that I finished restoring back in 2013 (DavesTR4A. com). It’s running stock lever type rear shocks that other than cleaning and painting and adding new links, I just reinstalled in the the car during the restoration. They seem to have resistance when I push/pull them so I am pretty sure they work as designed. 
The car has always been kind of skittish on rough roads and I am considering switching to a tube shock conversion, specifically the one that bolts directly to the existing shock mounts.
Originality isn’t my main focus here. I like to drive it aggressively.
I would be interested in anyone’s experience with switching from rear lever shocks to chassis mounted (using the stock shock mounting points) regarding handling improvement or not.
Thanks in advance,
Dave Connitt
‘67 TR4A-IRS
