Short type shock for use with IF15/IF15W. Utilizes the same ultra small flush fit screws for fixing the piston as the IF14-2. (A dedicated 0.05" size tool is required - A0100 INFINITY 0.05" Hex wrench driver). The same stroke as the STD shock is achieved by the use of a single O-ring together with a new shock tower (G153,G155,G156). When used on the front of IF15 the shock is 6.5mm lower (5mm shorter) than STD. When used on the front of IF15W the shock is 3.5mm lower (5mm shorter) than STD. When used in the rear of IF15 the shock is 3.5mm lower (4mm shorter) than STD. When used in the rear of IF15W the shock is 4mm shorter than STD. 2x1.1mm pistons a piston set is also available with a range of 1x1.3mm/2x1.1mm/3x0.9mm. In the case of use with IF15W the racing body SMJ C235 can be optimized and mounted 3.5mm lower when using G153 low front shock tower.
