An industry breakthrough when introduced in 1992. Since then, the accuracy and simplicity of Cloyes Hex-A-Just system remains unequaled by competitors. The Hex-A-Just True Roller Set is infinitely adjustable to +/- 6 degrees. No machining required and no fumbling with offset bushings. Simply dial in your cam timing with the turn of a wrench, then tighten the cam bolts to lock the cam position in place. When combined with Cloyes Quick Button Two Piece Timing Cover, this Cloyes' patented technology will ensure accurate timing and save you hours of valuable set-up time. Set it, and forget it.
Sprockets are machined from premium billet steel on our state-of-the-art CNC equipment. Both sprockets are then induction hardened and oil-quenched using our in-house multi-stage heat treat process. Premium True® Roller chain features 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. An additional feature on Chevrolet applications is the Cloyes' patented "cheater" sprocket tooth profile that provides improved chain wrap and smoother transition. Whether your destination is the street or the track, Hex-A-Just® will get you there faster!

Ventajas de Comprar un Juego Completo
La compra de componentes individuales puede ser menos costosa por adelantado, pero un Juego de Cadena de Distribución y Componentes completo proporciona beneficios adicionales:
✓
mejorar Motor Rendimiento: Una cadena nueva puede no encajar con unos piñones desgastados, y unos tensores / guías desgastados no aplicarán la tensión suficiente, lo que en última instancia se traducirá en un mal rendimiento del motor. La sustitución conjunta de todos los componentes de sincronización hará que todo el sistema funcione con mayor eficacia.
✓
Ahorre Tiempo y Dinero:El coste del kit suele ser inferior al de comprar todos los componentes por separado, y sustituir todos los componentes al mismo tiempo significa que sólo tendrá que hacer el trabajo (o pagar la mano de obra) una vez..
