The HTR Clutch line-up was designed to hold higher capacity power than the STR while still retaining a relatively moderate clutch pedal. 

[HTR2CD] - HTR Twin Plate dampened clutches give some forgiveness to the transmission by absorbing drivetrain shock while providing reliability and strength under heavy abuse. These units are typically good up to 650lbs ft of torque depending on the application. The end result is a quiet and reliable clutch set that will go years before needing overhaul.
