4.35" Side Bites - FCS Compatible, Hexcore. These side bite fins are engineered to provide maximum performance when added to a single fin on 2+1 surfboards. The 4.35" dimension offers excellent drive and hold for more powerful, committed surfing. Hexcore construction combines durability with responsive flex characteristics ideal for demanding conditions.
The side bite for the maximum amount of performance when added to a single fin on 2+1 surfboards — an extra-large template aimed squarely at performance longboards in powerful waves.
Put these on a 2+1 performance log you surf hard in steep, powerful surf — they turn the board thruster-adjacent, with rail grip that holds through hard, committed turns. For most mid-length 2+1 setups this is more side bite than you need, and if the board tracks or feels stiff through transitions, step down a size.
The 4.35" side bites are the largest in True Ames' standard side bite range, an extra-large all-around template built for performance longboards run as a 2+1. They are made in Hexcore construction with FCS-compatible tabs and are typically run alongside a 7" to 7.5" center fin.
