Alto, 'Performance steel' steel clutch drive plate set

Alto, 'Performance steel' steel clutch drive plate set

Steel drive plate set only. This 'Performance Steel' drive plate set is identical to the Alto 'Kolene-steel' drive plates, with the salt bath heat treated nitriding hardening process. But these Performance Steel plates are polished to achieve a lower RA controlled value surface, a smoother surface basically. This microscopically smoother surface reduces hot-spotting which helps reduce heat built-up and the occurrence of plate warpage. In short, this is an excellent clutch plate set for stock to very high performance engines and a direct replacement for the OEM clutch plate set. Incl. 5x 581912 (0.063"/1.6mm thick), 2 x 581913 (0.078"/1.98mm thick) and 1 x 581914 (0.079"/2.01mm thick) plates. Note: Compatible with OEM components and friction plates. A matching high performance Alto G3 Black friction plate kit can be ordered separately as 581910.

Fits: > 18-21 M8 Softail; 17-21 M8 Touring
