The supplied instruction sheet lists 50 ft-lbs for M10 × 1.5 fasteners when using ARP lube. The previous product listing stated 54 ft-lbs without a lubricant condition. These specifications conflict; confirm the correct specification for this kit and lubricant with RTS/ARP before tightening. Do not apply the lubricated specification to dry threads.
