Our 10PK FEAD system is designed to suit our FDFI based TVS2300 and TVS2650 LS Superchargers and is an upgrade to our existing 8PK system. Our 10PK FEAD is designed to fit the standard ATI balancer available for LS engines and is supplied with an upgraded wider idler mount with a higher lower pulley position to enable the fitment of a larger balancer pulley.

Due to the limited belt lengths available our upgraded 10PK drive system must use the newly designed Harrop Heavy Duty Tensioner manufactured from billet 6061 aluminium. The Harrop LSA style Tensioner has 10deg more radial travel than the OEM tensioner providing more flexibility with belt lengths and is also fitted with a heavier spring providing up to 40% greater load at full travel. The new Harrop LSA style Heavy Duty Tensioner is ideal for our 10PK and 12PK FEAD systems minimising belt slip but can still be used with the OEM 8PK system.
