7.5 GM Rear End Parts


7.5 GM Ring and Pinions

High quality racing ring & pinions from Motive and Richmond gear.
Important  To determine which ring gear you need (thick or thin) you MUST know the stock gear ratio that the rear you are building originally came with.
If the original ratio was between 2.00 and 3.15 you will need the thick gear.
If the original ratio was between 3.15 and 4.10 you will need the thin gear.
If you do not know the original ratio which was in the rear you are working on you may be able to determine this by measuring the ring gear. Click on link below to see table.
