1.000″ x 30″ TORSION BAR 3/4″ GUN DRILLED – 1 1/8″ O.D

Description

Strange Oval bars have 1″
of bearing surface on each end
of the bar. All other brands
have 2″ – that’s 2 additional
inches of bearing surface that
we eliminate (overall) that we
use to increase the bar’s
effective length. Our
effective length is 24″ (our
Sprint car bars have a 23″
effective length) while all
others are 22″. We also
increase our bar’s O.D.
(Gun-drilled bars only) to
compensate for the bar rate
vs. increased effective
length. This further increases
the strength of the bar. The
effective length provides a
more reactive, durable and
stronger bar that retains its
original rate over a longer
period of time.

Many
torsion bars are made from
4340 or a lesser grade
steel…NOT OURS! Strange Oval
uses aircraft chrome vanadium
steel which offers superior
yield strength, fatigue
properties, and impact
strength. We use this
proprietary aircraft steel
which is high in carbon and
Vanadium content. The high
carbon content allows for
increased hardness/strength
and the Vanadium alloys have a
higher Shear Modulus and
elongation.
Bottom-line….this enables
the bar to be stressed to a
much higher point (20%-30%) as
compared to the common use of
4340 steel and also
contributes greatly to bar
memory without any ride-height
change.

Superior
material allows for unmatched
bar hardness (Rc60
surface/Rc50 core), which
equals superior strength,
consistency and dependability.
Strange Oval bars have a
hardness of Rc60 surface and
Rc50 inner core. The next
closest competitor bar is Rc52
surface & Rc46 inner core.
So what does that mean? As the
bar twists, the harder and
stronger the bar material is
AND the longer the bar will
last without permanently
yielding which means Increased
bar LIFE….period!
