LSX
engines are taking the
performance market by storm.
To answer the needs of engine
builders who are testing new
limits, Compstar has
developed the widest range of
LSX crankshafts available
anywhere. Regardless if your
application is road race,
marine, circle track, or
street/strip, Compstar has
the configuration you need.

Made from 4340 steel
that is deep nitrided for
strength and wearability,
every Compstar crank is
intended for high output
installation. Compstar LSX
crankshafts are
counterweighted for enhanced
bearing load distribution,
which allows these shafts to
withstand both high boost and
high RPM applications.

Machined with large journal
radii, gun drilled mains, and
fully lightened rod journals,
the Compstar LSX crankshaft
is truly built for
performance. For tall deck
block engine builds, strokes
up to 4.250 inch can be
specified to create large,
reliable CID. Should you wish
to reduce rod journal surface
speed, 2.000 inch journal
diameters are available.

To accommodate your engine
control system, Compstar LSX
shafts can be specified with
either late LS2 – LS7 58
tooth or the early LS1 – LS6
style twin timing wheels. If
you are building a dry sump
LS7 style engine, Compstar
offers an extended length
post to easily complete your
project. Compstar LSX cranks
are sold rough balanced to
1750 grams, or finish
balanced to your bob weight.
