Do you want to add a little rock to
your stick? Since most of us are so addicted to 4 wheeling, why not add
something special to our rigs that we can enjoy each time we shift gears?
Replace your shift knobs with RockNobs. That's right, real rocks. RockNob
offers hand-crafted gear-shift knobs made from river rounded rock found in the
mountains and deserts of Utah. Each RockNob is hand picked so it will fit
comfortable in the palm of your hand. RockNobs come in various shapes,
sizes, and colors.
There
are 3 different types of RockNobs to choose from: Granite, Moab, and Timpanogos.
The Granite RockNobs are found in Little Cottonwood Canyon near Salt Lake City,
Utah. The Moab RockNobs are weathered sandstone rocks found in the deserts
of Utah. And the Timpanogos RockNobs are found below Mount Timpanogos
around the ancient shorelines of Lake Bonneville. Each RockNob has their
unique lizard petroglyph carved into the stone and is colored black on some of
the lighter stones for better visibility.
Before
you place your order for RockNobs, you must determine the style of RockNob you
want, the size of the RockNob you want, and the thread size of your shifter.
There are 2 sizes of RockNobs to choose from. The diameter of the
"normal" size is about 2 1/2 inches and the diameter of the
"large" size is about 3 1/2 inches. If you have big hands
or just like to have a big knob, you may want to order the "large"
size RockNob. I ordered a "large" RockNob for the transmission
shifter and a "normal" one for the transfer case.
There is a great thread sizing
chart on their web site (www.rocknob.com) which shows you how to measure the
thread size and pitch of your shifter. There is also a printable thread
chart if you wish to use it. I kind of cheated and just grabbed my tap and
die set to see which sizes I needed for the transmission and transfer case.
I guess you could also thread a nut on the shaft or thread a bolt into the shift
knob to determine what the thread size you need.
Installation of the RockNobs is
really easy and only takes a few minutes. Each RockNob is supplied with
jam nut so you can align the rock in a comfortable position and lock it in.
NOTE: Do not thread
the RockNob all the way in especially if you are installing a Moab RockNob.
Sandstone is weaker and more brittle than normal rock and it can crack if the
shifter bottoms out. Always use the jam nut to lock the RockNob in place.
However, the new generation RockNobs have an insert near the top of the threads
that will indicate when it is time to stop tightening the knob. When it
becomes physically harder to turn, it is time to loosen the RockNob to the
desired position and tighten the jam nut.
