AV&V Extreme Duty Replacement valves These superb valves are one piece forged from a racing grade stainless steel alloy. Each valve has a bearing quality hardened tip to prevent premature wear with high-lift applications. AV&V Extreme Duty valves also feature a 45° angle below the lock groove to reduce the stress in this area and to facilitate the valve seal installation. Each valve is heat treated with a special process and the stem is centerless grinded to a micro finish for a longer life. valve type Shank diameter Length diameter Model Year Coating 53-2182 Exhaust 1.355” 4.635” .3106” 883 Sportster (5/16 stem) Black 53-2183 Intake 1.590” 4.550” .3108” 883 Sportster (5/16 stem) Black 53-2016 Exhaust 1.562” 3.510” .3392” 900/1000 Ironhead Sportster Black 53-2017 Intake 1.812” 3.600” .3110” 900 Ironhead Sportster Black 53-2019 Intake 1.940” 3.600” .3110” 1000 Ironhead Sportster Black 53-2167 Exhaust 1.720" 4.560” .3106” 1200 Sportster (5/16 stem) Black 53-2168 Intake 1.485" 4.480” .3108” 1200 Sportster (5/16 stem) Black 53-2020 Int/Exh 1.750” Knucklehead Black 53-2021 Int/Exh 1.750” 3.825” .3765” Panhead Black 53-2021 Exhaust 1.750” 3.825” .3765” Shovelhead 66-84 Black 53-2024 Intake 1.940” 3.875” .3770” Shovelhead 66-84 Black 53-2025 Exhaust 1.615” 4.525” .3106” Evolution 1340 1984 & Up Black 53-2026 Intake 1.845” 4.455” .3108” Evolution 1340 1984 & Up Black 53-2026 Intake 1.845” 4.455” .3108” Twin Cam up to 2005 (5/16 stem) Black 53-2007 Exhaust 1.570” 4.525” .3106” Twin Cam up to 2005 (5/16 stem) Black For 2005 & Up Twin Cam use 7mm triple groove valves on previous page AV&V valve seat inserts These valve seats are made from heat resistant and wear resistant high quality alloy steel and are manufactured with clear convenient identification marking and radius edges for easy installation.
