It is the sm diff conversion. The diffs are stock ofna buggy parts (ofn19001 ring gear/ ofn19028 pinion/ ofn19004 diffcase/ ofn19002 spyder gears / ofn18076 bearings). The case that holds the spyder gears is still plastic but much beefier. The 4 spyder gears are metal and the shafts that support them are much thicker. I posted the previous message before leaving to go bash before work. I got out to a bash spot, fired up & ran for about 5 min and the tranny blew
Got home from work tore it down and found I broke the pin that holds the input gear on the spur gear shaft and stripped the input gear. My 2 speed assembly didnt strip but you can see signs of stress in the teeth. The input assembly & 2 speed assembly have had a long lived life(7 gal pro.15/ 8 gal cvr / 4 gal .25 / 3 gal 8 port / 2 gal .26). The rrp primary gears were installed after the first 1/2 gal from the cvr. They look worn but should hold for the rest of this season and maybe next. Hopefully some place is open tomorrow that has the input gear.
