Trask Performance Clutch Kits: Race-Proven Grip for High-Output V-Twins

When you push a Harley-Davidson to its limits — whether through a big-bore build, a forced-induction setup, or simply wringing out every ounce of torque from a stock motor — the factory clutch becomes the weak link. Trask Performance has built its reputation solving exactly that problem, engineering clutch solutions specifically for high-output V-twin motorcycles that leave stock components gasping. Explore the full Clutch Kit category to see how Trask stacks up against the field.

The Trask Power Plate: Engineering Meets the Street

The Trask Power Plate is designed for Big Twin and M8 slipper clutches to handle up to 200 HP with improved performance. What makes this more than a simple swap is the engineering behind the clamping force. One of the standout features is its ability to practically eliminate clutch slippage, achieved through the application of over 300 lbs of pressure to the clutch pack, compared to the stock 198 lbs, resulting in dramatically increased clamping force.

The kit is race engineered and race track proven, designed for high-output M8 engines, and features a precision machined billet aluminum power plate with high-performance springs and chrome 12-point hardware — and it's made in the USA. Designed as a bolt-on solution, it is engineered to extract the maximum potential from your motorcycle's power plant, specifically targeting Big Twin and M8 slipper clutches up to an impressive 200 HP. For riders who prefer a more subtle approach to installation, that bolt-on simplicity matters enormously — no primary teardown, no specialty tools, just a meaningful upgrade in under a few hours.

AIM Variable Clutch VP-SDR Series: Built for Torque Monsters

For those who need to harness the monster power of a V-Twin motorcycle, the AIM Variable Clutch Plate is designed to hold the power of the biggest torque monsters on the streets. The VP-SDR Series is engineered around the Harley-Davidson Assist and Slipper Clutch architecture, covering a wide range of Big Twin applications and offering fitment across multiple stud configurations. With OEM 2013 and 2017–2018 M8 springs, it handles up to 160–170 lbs-ft of torque.
