I think those having slipper issues will have hvae better success by adding the washers or extra washer behind the slipper thrust spacer rather than between the spring and slipper plate...In essence your adding one or two more slipper thrust washers instead of the one supplied and recommended for use on the kit (as described per manual instructions)..This has been the only remedy I have needed for my slipper in the truck...No slipper clutch basket needed??

Also if you have so much heat being produced in the rear area I would check and make sure you installed the slipper thrust spacer in correctly (Its behind the spur and rear pulley)..To get to it you have to dissesemble the rear and slide the motor out..Check to make sure its in right side up as the manual shows..This has caused many (that I have read and seen) to overheat the rear housing while also melting there slipper pads, spur gear, and there slipper spring...This can cause alot of damage in the slipper assembly while subsequently destroying the slipper thrust bearing.. Hope this adds some insight to those running into slipper issues..
