• 916358 is the OEM-diameter front accessory drive pulley for these ATI Super Damper assemblies; select an overdrive or underdrive variant (916359A, 916153, 916105, 916106, 916159) if a ratio change is desired
• Sold individually

Features

• OEM-diameter 6-groove serpentine pulley at 7.525" outside diameter - matches factory accessory belt drive ratio exactly for street-driven applications
• Front drive crankshaft pulley designed to mount onto ATI Gen V Super Damper assemblies for GM LT-based truck engines
• Steel construction with black oxide finish - strong, corrosion-resistant, and purpose-built to handle the sustained belt loads of a supercharged or high-power Gen V build
• Eliminates the need for a separate bolt-on blower pulley - the ATI Super Damper system integrates the crank pulley function directly
• Available in multiple overdrive and underdrive diameters for boost tuning - 916358 is the baseline OEM-size starting point
• Made in the USA by ATI Performance Products

Product Description

The ATI 916358 is the OEM-diameter (7.525") 6-groove steel front drive crankshaft pulley for ATI's Gen V LT truck Super Damper assemblies (PN 918645 and PN 917306). ATI's Super Dampers for the Gen V EcoTec3 truck platform are sold without a front accessory drive pulley - the 916358 must be added to complete the assembly and maintain factory accessory belt drive ratios on the 4.3L LV3, 5.3L L83/L84/L8B, 6.0L L96, 6.2L L86/L87, and 6.6L L8T engines.

At OEM diameter, the 916358 preserves factory alternator, A/C, and power steering drive speeds - the correct choice for any build where accessory drive performance or voltage output needs to remain stock. For builders seeking boost changes through drive ratio adjustments, ATI also offers the 916359A (10% underdrive), 916153 (4% overdrive), 916105 (10% overdrive), 916106 (15.5% overdrive), and 916159 (30% overdrive) as alternatives. Made in the USA from steel with a black oxide finish. Sold individually.
