Best Slipper and reverse questions

[Major Azzwoopin]

7XL motor too BTW.....no problem really. I would like to have reverse. ...I meant internal, inside the tranny gear mesh.
As for the SLipper...I am using a RRP metal spur. and I am smoking the stock slipper (pad) in less than 1 minute maybe even less than 30 secs. I measured the spur temp just outside where the pad is covered and pressed against the spur at 365 degrees after it failed once.
