High quality racing ring & pinions from Motive Gear.
If you do not know if the original ring gear was thick or thin you may be able to determine this by measuring the ring gear. Click on link below to see table.
All 8.5" GM gears are available in thin ring gear only. If you are replacing a thick ring gear you must order a ring gear spacer.
