Ace Redrive - 4-Stroke Single Engine V-Groove Belt PSRU (200-460cc)

Ace Redrive – 4-Stroke Single Engine V-Groove Belt PSRU (200–460cc)

The perfect PSRU for small 4-stroke single-cylinder engines — lightweight, reliable, and built to Ace Aviation's exacting standards.

Not every build needs a big V-Twin. For ultralight aircraft, trikes, powered parachutes, and light experimental builds running smaller 4-stroke single-cylinder engines, the Ace Aviation Single Engine Redrive delivers everything you need: a precision belt drive, premium SKF bearings, and Ace's signature eccentric shaft tensioner — all in a compact, lightweight package that won't eat into your useful load.

With over 700 Ace redrives flying worldwide and now available through the exclusive US & Canada distributor, you get factory-quality engineering with domestic shipping and real US-based support.
