Thrust bearings are used at the lower spring seat to reduce friction when
adjusting ride height. New stainless cap-style seats, a VariShock
exclusive, enclose the thrust bearing to keep dirt out.
Also available is an exclusive spanner wrench, incorporating four tangs,
which will not slip off the lower spring seat because it engages the seat
in four places (not one, like common spanners).
The VariShock coil-over-spring compressor greatly eases lower spring-collar
adjustment on high-preload or high-rate applications. Heavy-duty plates
at each end fit 2-1/2 inside-diameter coil springs of 130 lb., rate
or greater, with a maximum spring height of 14.
