Stage 2 gets rid of the short, almost-coil-bound top springs on the rear
Podiums and adds ST’s custom top
springs and aluminum spacers to get
rid of almost 3/8th of an inch of slop
in the OEM lower spring. Aluminum
cross-overs determine when the shock
switches from the new ST spring to
the higher-rate stock spring. This kit is
$575.60, and the improvement over
the OEM-spring ride is incredible. The
Stage 2 Fox Edition cures all bucking in
whoops and really balances out the ride
in cross-grain terrain. With the front and
rear torsion bars, the ST Fox Edition
feels totally connected to the trail yet
floats over the nasty stuff.
We increased trail speeds considerably and were hitting obstacles harder,
so we occasionally bottomed the front.
We compensated with two more clicks
in on front compression (to five).
Stage 3 is four ST top springs and
6061 silent cross-over rings and spac-
ers for $875.40. With the longer top
springs and crossovers, the ride quality
is amazing at both ends. Trail garbage
is unnoticeable within the cabin, and
cupped holes on the hardpack trail are
soaked up like magic. With the Stage
3 mods, we initially went back to fully
out (zero) on the compression clickers
and went in two clicks to prevent bot-
toming up front on the nastiest hits.
We increased trail speed again, but
the chassis stayed planted for course
Here’s the Fox Edition IBP sleeve with three offset reed valves and the shock-shaft assembly. Notice that the compression valve stack is backed up by a large
spring that allows additional blow-off on big hits. ST stiffens the reeds, frees up the compression side of the piston, and lightens overall compression valving for
Here’s the Stage 4 Fox Edition spring kit with silent cross-over collars and
spring spacers. Front springs are 3.0 and rears are 3. 75 inches. Individuals sell
for $199 and $249, respectively.
Although the Shock Therapy Stage 4 spring/valving package was intended to
smooth out the ride in desert chop and dune ruts, we couldn’t resist taking it
on the LOORRS track at Glen Helen Raceway. Nosediving under hard braking
is kept to a minimum.
