The shock absorber is a vital component of the suspension
system as it controls body roll and suspension throughout
its travel. For anyone wishing to upgrade from the standard
shocks found in the suspension packages in this catalog, we
recommend QA1 shocks.
The 12 different dampening settings on the QA1 shock offer
you the adjustability needed to get around the most
difficult turns whether on the street or track. The superior
dampening control assembly is second to none. Both bump and
rebound can be adjusted at the same time. Extensive dyno
testing, using all of the most popular shocks on the market
today, has proven QA1 shocks to be the most adjustable and
have the most dampening control of all.
QA1 shocks are also totally rebuildable. If the shaft is
bent or the seal damaged, they are replaceable. Damaged QA1
shocks returned to Held Motorsports can be repaired at a
fraction of the cost of replacement. Valving can also be
changed to tailor the shock to your individual needs. All
QA1 shocks are hand assembled to rigid specifications by
experienced craftsmen, though they are competitively priced
with mass-produced shocks.
The QA1 PROMA STAR has become the shock of choice to the
serious performance minded Fiero owner. Proma Star offers
external adjustment for quick corrections, to accommodate
changing road or track conditions. Only the best quality
components are found in every QA1 shock . The 5/8" Nitro-tec
piston rod is equal to stainless steel for corrosion
resistance and 40% harder than hard chrome. The seal
arrangement includes a multi-lip internal seal and external
wiper seal to keep the dirt out and the fluid in. The
graduated adjuster knob offers a quick reference for shock
setting, with 12 different positions that modify both bump
and rebound simultaneously. After assembly, shocks are dyno.
tested and grouped into matched pairs to assure the customer
of a balanced installation.
