Adjustable Single Chain Timing Set For 3-Bolt 4 Pole 58X GM LS

With more and more LS fans switching to a 3-bolt Cam for added strength and reliability, there came a need for a 58x 3-bolt timing set to accommodate a late model LS computer. The new COMP Cams LS Adjustable Timing Set provides super accurate timing and bulletproof reliability with a four pole reluctor and the 58x timing needed to work with late model LS computers. Featuring billet Steel sprockets and premium Roller chains, these new timing sets are machined on state-of-the-art CNC equipment to increase durability and reliability. The machined Cam sprocket uses a captured thrust bearing to reduce friction. Side plates are cut and shaved from high strength Steel and heat treated for maximum fatigue resistance.
