Product Info

There is a reason the True Ames Greenough 4-A Single Fin is the most iconic, functional and versatile single fin available... it works on just about anything! The Greenough 4-A has been True Ames' bread and butter for over 40 years now, and it is still the most popular single fin design there is.

A truly well-balanced fin...the full base coupled with the tapering, moderately flexible tip provides a solid amount of drive off the bottom, and an acute responsiveness through arcing turns. Designed for both speed generation and spending time surfing in the pocket, the 4-A is a fin that will hold when you need it to and release when the time is right.

The Smaller sizes (6" - 8") are phenomenal for 2 + 1 setups.

The larger sizes (8.5" - 10.5") are great to use for Single Fin setups.


Product Info

Staff Says Cleanline Staff James Says:

"True Ames specializes in making fins, and they know what they’re doing. The 4-A will hold when needed but release when you’re ready to smack the lip like pro longboarder Taylor Jenson. I use the Greenough 4A as a single fin and a 2 +1. The 9” works great as a single fin for my 9’ TJ Pro. The Greenough 4-A is one of the most popular fins we sell at Cleanline and one of the most popular single fins used worldwide."

Additional Info

A fin design is only as good as the materials used for construction. At True Ames, they carefully select the most well-suited types of fiberglass and wood for producing the highest quality fins available. In order to achieve the performance characteristics that have become the standard of solid fiberglass surf fins, True Ames uses E-glass. It is the most common type of fiberglass used in surfboard construction, and its qualities translate with great success into fin construction. E-glass has excellent flex characteristics and performance longevity, while featuring the bonus of outstanding color vibrancy that allows for the variety of colors we offer.

Love Cleanline….amazing (iconic) longboard fin & they give u candy

I needed a 9.75 4A for a new board…it was delivered quickly…but with starburst candy. I was very happy to eat the candy. I already knew I would love the fin, but I did not know I would be eating pink starburst while I set it up. 5 stars. Will order again.

Love it

Love these True Ames fins, using the 8" fin for a custom Greenough edge board; the fin is perfect and the blue color is amazing. GREAT price for a high end product.

Greenough Fin

Fin goes really well in my 7’0 Kris Hall single fin! I’m leaving this review however because the peeps at Cleanline sent me a handwritten card with my box which was very nice. I work in customer service myself and seeing that was a nice touch. Thanks y’all.
