The ultimate dual-rod steering cylinder; built with longterm reliability, durability
that would make Caterpillar proud, and the kind of overkill that makes us happy to
associate the Rockstomper name with it.
Wear band equipped
Mounts using four 1/2" bolts
Ends tapped 3/4-16 for spherical rod ends or tie rod ends (not included)
SAE O-ring-groove ports
1/4" steel cylinder barrel wall thickness
NitroSteel-100 rods--provides better wear life, increased rust resistance, non-chip finish, and increased strength,
over standard chromed piston rods

For an indication of how burly this is, the cylinder alone weighs over 20 pounds.
Dual-rod steering cylinders are recommended for steering consistency. They are
also known as "balanced" cylinders, because they balance the number
of turns and force avalable, for both left and right turns.
2.75" dual-rod full-hydro cylinder, $400.
Clamp mounting feet for the ultimate in mounting versatility.
2.75" bore cylinder mounted in radius base clamp feet with reversed fasteners (reversed fasteners available by special order).
Clamp feet include a special retention ring feature to prevent any cylinder walk side to side.
Clamp feet, $100/pair (please specify style).
Hydraulic steering Q&A:
There are a number of reasons we use such top-end componentry in our hydraulic steering
systems. Once you understand the reasons behind many of the parts involved, we feel
you'll agree that what we offer is simply the best bang-for-the-buck on the market.
Steel threaded gland nuts.
Many lesser cylinders are assembled with snaprings or lockrings. If these rings are
exposed to water, if the vehicle is driven in mud or rain, the rings can rust into
place. If those rings rust into place, the cylinder is nearly impossible to disassemble.
Most of those who use threaded gland nuts, use aluminum gland nuts. While they look
nice, aluminum simply does not have the durability or wear life of steel. We use
threaded steel gland nuts for longterm durability and easy rebuilding if it should
ever become an issue.
Additionally, steel gland nuts will not have problems with galvanic corrosion
destroying the threads and seizing them into the steel body of the cylinder.
Wear bands protect the cylinder walls, piston, and glands, from wear. With metal on
metal contact, as wear-band-less cylinders quickly develop just from the force of
gravity pulling on the piston, wear starts in. The cylinder piston usually shows
the first signs of this, being worn oblong--then the gland nuts, and if it continues,
the rods and the housing. Wear bands support the rod to prevent metal on metal contact,
much like a main bearing in an engine.
While probably unnecessary, our cylinder fittings protect the threads and seal surface
from damage. Many cylinders are assembled with brazed-on male JIC (AN) fittings, with
the threads readily exposed. If a fitting is broken off with a lesser cylinder, it's
a major problem--the cylinder has to be rebrazed back together. With ours, the fittings
are nearly impossible to break off, but even if one is broken off, the screw-in adapter
fitting will be broken off--not the integral fitting from the cylinder. The remaining
bit of broken-off adapter fitting can be easily removed with an EZ-Out or similar
extractor, and the fitting replaced--all right on the trail. Additionally, the use of
SAE O-ring ports allows for adapter fittings to be used to rotate the fitting inlet and
outlet to best match your needs.
We strongly recommend Valvoline SynPower synthetic power steering fluid for use in our
hydraulic steering systems.
The orbital control valve is the heart of the full hydraulic steering system.
