GM’s LS Engines
TRUE ROLLER SETS FOR ALL YOUR LS NEEDS!
We start with sprockets machined from premium billet steel on state-of-the-art CNC equipment. Both
sprockets are then induction hardened and oil-quenched using our in-house multi-stage heat treat
process. Our sprockets are made “oversized” to eliminate the chain slack found in the OE and
other aftermarket sets. The cam sprocket is machined for and includes a captured thrust bearing to
reduce friction. Our Premium True Roller chains feature superior strength with full roller action. Side
plates are cut and shaved from high strength steel and heat-treated for maximum fatigue resistance.
The .250” rollers are “cold rolled” and hardened to exacting standards increasing load and RPM
capabilities. All our LS sets are hand-matched at our manufacturing facility to qualify center distance
and run out. This is a Cloyes Exclusive - no one else in the industry takes the time and attention to
detail to ensure you get the very best custom set in each and every box.
We offer LS sets in our patented Hex-A-Just series allowing easy timing adjustment of +/- 6º, as well
as in our Race Billet series which are available with three or nine keyways.
New Coverage for Raised Blocks and also an EXTREME DUTY Race Chain!
LS sets now available with increased center distance for the RHS and other .390 raised blocks.
Also new this year, all our LS sets are available with the well-known racing chain currently being used
by the leading 24 hour endurance teams . . .
Cloyes True Roller “Z” Chain
The “Z” chain is the preferred extreme racing option offering unmatched strength and durability for
the LS team looking for all-out racing performance. The “Z” chain is standard on our raised cam LS
sets and available as an upgrade on all LS applications. YOU WON’T FIND BETTER!
