********Note: A signature upon delivery will be needed on this FedEx shipped item******** This is a lightly used set of ZOOM Pro-Gear Ford 9 Inch 5.67 ratio 28 spline gear set in the high impact 9310 nickel "drag racing" alloy (not the 8620 alloy "street" alloy). They were used for a short number of passes in an 1/8 mile drag car (something like 20-30 passes). They have a very nice drive/wear pattern on them from one case install. The ring gear has 34 teeth and the pinion gear has 6 teeth. The numbers on the ring gear = 9017 1d [heart shape] 2 USA 34-6 X The numbers on the pinion gear = 9017-2d [heart shape] 2 6 - 34 USA The part number on the box is #189017 Both the ring gear & the pinion gear have had their sharp manufacturing edges smoothed/rounded. And the ring gear teeth have been clearanced on the toe (inner) teeth edges for greater clearance between the teeth and an aftermarket 9" case's 3rd/rear pinion bearing housing (see pictures). It's been sitting on a shelf for years, so it needs to be cleaned before it's setup/installed to remove any dust and/or any residual Loctite that might still be on the threads. Asking $320.00 + shipping for this lightly used ZOOM Ford 9" 5.67 ratio 28 spline 9310 nickel alloy Pro-Gear set. Update: Asking $266.00 + shipping. This sale only includes the ZOOM Ford 9" 5.67 Pro-Gear ring & pinion set shown in the pictures. This sale does not include any other Ford 9" rear gear/housing/drive line related parts or equipment not shown in the attached pictures. It is the buyer's responsibility to understand that 9310 alloy Pro-Gear "drag-only" gears usually should not be used on the "street", and to also have the knowledge/skills to install this gear set correctly. There is no warranty associated with this used 5.67 Pro-Gear set, it is sold "as-is". All sales are final, there are no returns.
