Hypercoils are recognized
world-wide to be the best suspension coils available. For the past 37
years the winning cars at the Indianapolis 500 used Hypercoils. In recent
years nearly every car in the starting lineup up used Hypercoils.
As competition in motor-racing continues to escalate more
and more teams are discovering the performance advantage of Hypercoils.

Hypercoils are a different product than other springs
on the market. They are manufactured from the best materials to closer
tolerances. A wider range of wire sizes are available from stock so
proper sizes are selected to optimize the designs. In addition to
multiple inspections, Hypercoils undergo an exacting heat treat and
shotpeening process to ensure accuracy. Reliable and accurate, Hypercoils
are lightweight and generally offer more deflection. And most importantly,
they will not lose free length.
LIFETIME GUARANTEE: Hypercoils are guaranteed for life to the original
purchaser with proof of purchase from Hyperco or our authorized
dealers/distributors to remain within two percent of the original
manufacturing tolerances for rate and free length when properly
cared for and used in normal racing conditions.

Helper Springs

Helper Springs 2.25 and 2.50. Info on Helper Spring
-- Keeps the spring indexed in spring perchs when flying over holes
and when the car is on jacks. |
Hydraulic Coupling Device (HCD)
 |
Hyperco calls it "Momentum Technology". It's
two pieces of precision designed hardware that is placed on each end
of a coil over spring. The HCD allows the spring to pivot during compression
and extension. The result? A significant reduction in cross/axial
side loads and the accompanying friction that is associated with these
forces. In turn, this reduction of the side force and friction reduces
load and wear on shock seals and allows more force and energy to be
directed to the car's mechanical grip.
HCO designs are available to fit all popular damper/shock absorber
applications as well as customs.
