881 150 and 881 151 supercharger rebuild kits

[actis]

ok, from what i've been reading the 150 is a 150 hr steel washer kit and the 151 the 200 hr. the 200 supersedes the 150. that sucks. thanks for the info Tiny.

The 151 is the new 200 hour kit, but the 150 is not as far as my memory serves....

what are the differences between the 881 150 and the 881 151 supercharger rebuild kit. i bought them from two different sellers because i couldn't beat the price. $200 each. both kits advertised they were the 200 hour molybdenum rebuild kit for the non intercooled 185 hp engines. any insight on this? thanks
