Kevin I. ★★★★★

Wasn't sure these would line up right on my build, but the tabs drop straight into the 54mm motor tube with zero fiddling. Fit against the centering rings was clean too, no sanding needed. Solid fins for the price.

Eva C. ★★★★★

The tabs extending down to the 54mm motor tube made alignment with the rings effortless, and the fit was snug without needing any sanding. My build came together in an afternoon with zero guesswork.

Elizabeth D. ★★★★★

Cut the tab slots myself and they lined up dead straight with the motor tube—zero wobble once epoxied. These fins feel sturdier than the stock ones I replaced, and the 54mm tab depth gave plenty of surface to bond.
