I don=92t know  if the damping rates are different, but the lower mounts ar=
e. Both have a steel sleeve that passes through the rubber bushes. On the T=
R4A, that sleeve is part of the shock. On the TR2-4, it=92s part of the sho=
ck mount bracket and so is not sold with the shock absorber.

Cheers,

Cliff

I have a 63 TR4. Moss and Roadster Factory list different part numbers for =
the 4 and 4A. Physically I think that they must be the same, so different d=
amping rates? Does anyone know the difference? Could it be the change to IR=
S and overall handling characteristics?

Thanks

Allen, front suspension on a TR4 is same or similar to a TR3.  TR4A matches
TR250, TR6.  They are different specifically the upper arms, maybe other
differences as well.  Don't know about shock absorber spec differences, but
definitely a different, though similar, suspension set up.

While it may seem the same the 4 and 4A have different front suspensions
hence the need for different shocks.

Spring pan is different twixt 4 and 4A. Spacing on shock mounting studs is wider and shocks not interchangeable unless matching spring pan also changed. 

Ask me how I know that…
