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; the two diameters that cover the modern rear-shock catalog across all the major shock manufacturers. 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 is the official technical partner of multiple World Tour and downhill teams. The press faces are hardened and tempered; 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.
