shock preload tool

[Hank Wong]

Anyone got the tools to help me add a quarter inch preload to my Wilbers rear shock? My Wilbers rear shock does not come with a remote preload adjuster. The shock is off the bike. The two rings won't budge with the spanner wrench supplied with the Wilbers shock.

Hammer and a punch? ...It's not pretty but it's the traditional way. It's obviously easier if the shock is fixed to something like the bike of a vise.

Thanks for the reply, Rick,
The rings are loosened. It takes two spanner wrenches, one for each ring and turn them in opposing direction. You're right. It just takes a little good old fashion brute force plus some WD40. Of course knowing which direction to turn is cruical to the success. Youtube is handy that way. I was wondering if adding a quarter inch to the static sag really worth the trouble or if I should just ride without my panniers. I will find out soon enough. The new Wilbers shocks is not noticeable on the slab. It is quite noticeable in the twisties.
Thanks,
hank

Add a quarter inch of preload, it's 3/4" of sag.

You can use dryer hose clamps to compress the spring then adjust it by hand. I use three clamps with a cordless impact and 1/4 inch bit. You can do it on or off the bike.
