 Hi,
I am totally against switching from levers to telescoping shocks unless the=
 upper shock mount is both connected to the lower frame (or roll cage, if y=
ou have one) AND has accomodation for upper and lower bump stops. Otherwise=
, you are wasting money and will wind up with body and / or frame problems.
The lever type shock is actually better than tube shocks except other than =
modified levers, you can't adjust for conditions. That said, the Worldwide =
folks (nosimport.com) have a conversion with external adjustable valving. N=
ot state of the art, but you can dial soft/firm as needed.=20

The real problem here is that a lot of folks will add springs with no sense=
 of what the rates are and a lot of times the handling issues are related t=
o springs and shock not matched properly. Skittish on rough roads implies t=
oo firm, e.g. not enough compliance, but without knowing why there's a comp=
liance issue, you're sort of shooting in the dark. I mean, you could be see=
ing a problem because you're driving on the bump stops...
I switched to the Worlwide setup about 10 years ago and the difference in h=
andling was night and day. Plus I can soften the car when it gets wet.
Regards,Bob Lang
