Rear Shock Bushing Extractor Set

Rear-shock eyelet bushings wear. The shock moves on them every pedal stroke and every bump, and bushings that started as a press fit drift loose enough to let the shock body knock against the eyelet at the end of every compression. Replacing them is not optional; it is the maintenance interval that decides whether the shock works at low compression or starts hammering itself apart.

The bushings come out hard, though. A hand press, a hammer-driven pin, or whatever is on the bench tends to damage the eyelet bore on the way through, and a damaged bore means a new shock, not a new bushing. The 1701/5 is the press tool that gets the bushing out cleanly without loading the eyelet wall.

How the set works

The 1701/5 ships with the press hardware sized to act on 12 mm and 12.7 mm eyelet bushings, with a dedicated pin for each size. The press tool pairs with a bench vise: the vise supplies the press force, the 1701/5 supplies the geometry that concentrates the force on the bushing without spreading load to the eyelet wall.

Press the bushing out in seconds, press the new one in to the correct depth, mount the shock back on the frame. The whole sequence runs at the bench in the time it takes to remove the wheel.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The load is concentrated where the eyelet bushing meets the press tool and nowhere else. The geometry exists because the alternatives, punches and presses with mismatched faces, keep damaging the eyelet bore on the way through.

Pro tip from our mechanics

Rear-shock bushing service is the parallel procedure to fork lower-leg service. Different tool family, same service-interval logic: a bushing that has done its mileage no longer holds the shock body square in the eyelet, and the symptoms read like a tired shock right up to the point you tear the shock down and find the bushings are the fix.

FAQ

What bushing sizes does the 1701/5 fit? It presses out and installs rear-shock eyelet bushings in the two common diameters, 12 mm and 12.7 mm. The set carries a dedicated pin for each size; pick the pin that matches the bushing and assemble the tool around the eyelet.

Do I need a shop press to use it? No. The set is designed around a bench vise: the assembled tool and the shock eyelet go between the jaws, and closing the vise presses the bushing out. The old bushing collects inside the press body, where it is easy to remove.

Does it install new bushings or only remove old ones? Both. After the worn bushing is pressed out, the new bushing is set parallel to the eyelet opening and pressed in with the same tool and vise until it is fully seated in the housing.

What comes in the set? Three pieces in a labeled plastic case: the press body that receives the pressed-out bushing, a 12 mm pin, and a 12.7 mm pin. The whole set weighs 300 g.
