Specs At A Glance

Good To Know

Q: Do I need to recharge the shock after installing this seal head? A: Yes, the shock must be refilled with oil and pressurized with nitrogen after the seal head is installed, since the unit is opened during the job.

Q: Will this fit every YZ250 rear shock from 1980 to 1988? A: It is listed for those model years, but shock variations exist, so compare your old seal head against the new part before assembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
