First fork services usually stretch across three tool orders and four weekends; the 1704 is the other path. Chamferless flat sockets for top caps, a strap wrench for air-can collars, the bushing extraction and install tool, parallel-jaw pliers, and seal installation guides arrive in one fitted tray, covering lower-leg service through air-spring and bushing work.

A first suspension service usually goes one of two ways. You buy the right tools as you discover what each step needs, and the service stretches across three orders and four weekends. Or you buy the kit that the procedure calls for once, and the first service is finished in the time it takes one weekend to pass. The 1704 Suspension Service Set is the second path.
The kit ships with the tools that a fork service depends on across the bench: flat sockets for top caps that a chamfered socket would round, a strap wrench for stubborn air-can collars, the workshop pliers that the bushing-extraction step needs, hex keys at the diameters fork bolts actually use, the small-drive socket sizes the procedure calls for, the bushing extraction and install tool itself, and the seal installation guides matched to the stanchion diameters the fork is built on.

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 1704 is the kit we hand to a mechanic doing a fork service for the first time; every tool the published procedure calls for, no upselling, and the bushing-extraction tool that turns the 100-hour service into a benchable job rather than a service-center referral.
Pro tip from our mechanics
The 1704 is the home-mechanic starter kit for a lower-leg service. The Suspension Service Set 2.0 is the companion option with an expanded seal-driver assortment; if your stanchion diameter is not covered by the 1704's bundled drivers, the 2.0 is the kit that fills in the rest of the size range.
Tech Tips
How to service your suspension fork's lower legs
From the press
Fork seals do a fantastic job of keeping the grit and grime out for your fork which still allows the stanchions to slide freely through. To achieve this monster task, you need to have a tight fit, and if you've ever removed or replaced the seals on your fork, you know how hard it is to get the suckers back in there, let alone to get them seated straight.
From finishing up cable housing to finagling suspension wipers and seals out for servicing, a set of Awls or dental picks removes a considerable amount of faffing from precision jobs. Available in straight or bent varieties, Unior's Awls can be purchased individually or as a set. Each has an ergonomic handle and a round blade hardened steel.
