[TR] TR4A rear dampers (shock absorbers)

I noticed that some shops rebuild the dampers for heavy duty.  Is there a
special weight of oil to upgrade the dampers or is there a rebuild and valve
switch out required. I too need to rebuild my dampers and want to upgrade
their performance as I have Moss competition leaf springs and ARE bronze
bushings ready to install. 
Thanks,

I, too, use fork oil from a local motorcycle shop.  It is available is
various weights (10, 20 & others).
