By today's standards, it very heavy and with just 26mm stanchions it is very spindly, but the ride quality is still very good, especially with the coil spring upgrade fitted.
Some DH3's had a compression knock, this was due to the build up of internal pressure when the fork initially moves. The simple solution was to drill a relief hole on the side of the damper rod about 7mm under the head.
We made a service guide which you can follow here, however the 26mm genuine forks are no longer available.
This is what Marzocchi said about it at the time:
The DH3 fork is designed specifically for downhill biking. The forged, reinforced crown, the forged T6 stanchions and the extremely rigid brake arch, combined with extended travel and controlled damping, absorb every type of shock without undermining stability.
The oversized tubes make the DH3 one of the most rigid forks on the market. As on the other models, the practical 6-position adjuster knob means the MTB can be adapted to any kind of terrain.
The DH3 was developed with disc brakes in mind, and consequently various adaptors are available
