TR4/4A TR4 rear tube shock conversion


Jedi Hopeful
Anybody use or see one of the rear tube shock conversions for TR4 straight axle cars? I saw a company selling them on ebay last week, but I can't seem to find them now.

Anybody know anything about these?

Kas Kastner's latest book discusses a tube shock conversion for beam axle cars, but that may only be for racing applications.

With the type of modifications you want to make, that might be a good reference. NFI, but great book.

I like lever shocks. /ubbthreads/images/graemlins/devilgrin.gif

haha, i'm going crazy here. my recent calcuations have yielded a new formula:

cold weather + warm shop + internet research + lack of porsche projects = wallet getting thinner^(triumph fun)

FWIW in Roger Williams book "How to Improve Triumph TR2-4A", he hardly mentions tube shock upgrades for the live axle cars. He does mention that Cambridge Motor Sport (www.cambridgemotorsport.com) offers "a rear telescopic conversion for ultra fast road cars, although there is very little room between the wheel and the inner wheelarch. The solution from Cambridge is a modified inner wheelarch with internal turret."

Williams advocates using either larger lever shocks as used on the TR4 Rally Cars or lever shocks with modified control valves "available from most specialists" including Cambridge Motor Sport.

BTW after reading about your engine modifications, I think your car will fall into the "ultra fast road car" category /ubbthreads/images/graemlins/grin.gif

Good Luck.

I'm with Larry on this one.....I'm sort of looking for a performance upgrade, but also sort of looking for a modern/reliable upgrade. I've had no problems with my lever shocks, but my latest efforts are trying to bring it up to the 21st century....just using the car as a test bed for modern improvements (although, a coil-over setup would better satisfy that desire).
