High Performance Steel Clutch Plate Set for Harley-Davidson

Steel clutch disc set.

This high-performance steel clutch plate set is identical to Alto's Kolene steel, with a nitriding hardening process and salt bath heat treatment.

However, these high-performance steel discs are polished to achieve a surface with a lower controlled AR value, a smoother surface.

This microscopically smoother surface reduces hot spots, helping to reduce heat buildup and disc warping.

In short, this is an excellent clutch plate set for stock and very high performance engines, and a direct replacement for the OEM clutch plate set.

Includes... 5 581912 discs (0.063"/1.6 mm thick), 2 581913 discs (0.078"/1.98 mm thick), and 1 581914 disc (0.079"/2.01 mm thick).

Note: Compatible with OEM friction discs and components.

A high-performance Alto G3 Black friction disc kit (code 581910) can be ordered separately.

Fits: Softail > 18-24; FLT/Touring 17-23 (except FLTRXSE and FLHXSE 2023)
