26 Big Twin 4 speed transmissions have been built since 1936 in several versions. They were included on bikes with Knuckle engines, Pans, Shovels and some '84 and '85 Evolution 80's. They all used this transmission. With Andrews 4 speed gears, transmissions last longer, shift faster, and just plain run better. Bikes with Andrews gears feel so good that its hard to believe until you experience the difference for yourself. 2.44 1ST GEAR SET (1959 thru 1984) Part #201105 Best choice for Superglides, choppers and lighter bikes with stock or smaller motor or trans sprockets. This is a no clunk, 48 mph, 1st gear. Installation in '80-84 FX requires 21T (1.82 ratio) 2nd gear for this 1st gear. 2.60 1ST GEAR SET (1959 thru 1984) (Not shown) Part #201145 This gear set works best with E glides and heavier bikes with motor or trans sprockets having more teeth than stock sprockets. Installation in '80-84 FX requires 21T (1.82 ratio) 2nd gear for this 1st gear. 3.00 1ST GEAR SET (Original stock ratio) (Not shown) Part #201090 (Not pictured) (1959 thru 1984) Part #201094 (Not pictured) (1936 thru 1958) Stock replacement first cluster and countershaft gear.

COMBINATION 2.24 1ST- 1.65 2ND GEAR SET (Not shown) Part #201020 If you want peak RPM thru the quarter mile, this gear set will provide the super close ratio shifting to handle it. OK for street or drags with any size motor. STOCK 2ND GEAR (1.82 RATIO) Part #202160 (replaces H/D# 35751-36) Stock 2nd gear with face milled drive dogs for more positive 1-2 shifts.
