Spool Performance Spool HELIX Overdrive billet Aluminum vac cover mounting plates

The Aircraft grade Aluminum Billet plates are manufactured as an insurance policy against the stock cast OEM plates from developing hairline cracks while subjected to increased stresses from the HELIX unit.

Only a small fraction of the cars have inferior castings but it is recommended to use the billet plate while using the Helix.

Please note that all new Helix orders include this mounting plate in the kit, so no separate purchase is necessary. This listing is for customers that previously ordered the Helix and did not receive this mounting plate. Please include the order number/name of the original HELIX order in the order notes and we will refund the cost of the billet plate.
