ISKY SPRINGS 1.625 OD ROLLER 250-675PSI @ 2.020 .750 LIFT

Description

Introducing Isky’s new
RAD-9000 process option for
Tool Room valve springs.
Under trade secret
Radial-Densification (RAD),
the physical properties of
Tool Room springs are
optimised for even greater
surface to core uniformity.
To insure they’ll withstand
the tortures of sustained
high rpm operation, we
subject each batch to the
most rigorous real world test
standard ever created,
SPINTRONTEST II. It’s a no
holds barred run as high as
9000 RPM where for over 1,000
miles, race ending
competitive abuse is
continuously revisited. This
pass or fail benchmark is the
only test of its kind in the
performance industry and
every set of Tool Room
springs conforms to its high
standard.
