Welcome to Gear Grinders 4 Wheel Drive Club!

Established in 1971 and located in Ridgecrest, California, we are a family oriented group of four-wheelers dedicated to promoting responsible off-road fun and protecting our natural resources.Our club takes pride in its support of Tread Lightly on Public lands. We are comprised of outgoing, fun loving, patriotic and responsible members who share the same love of off-roading and the outdoors. Guests are always welcome, so contact us if you will be in the area.  We’ll let you know where we are going and when.

Isham has been severely washed out over the past two years and this has significantly increased the technical nature of the run. It is more like a Hammers trail now. It is strongly recommended that vehicles have 35" tires, front and rear lockers, winch, body armor/rock sliders. Additional useful items: Spare parts as applicable to your vehicle (eg., u-joints, rear driveshaft), tire repair kit/spare tire. Long arm lifts will work far better than short arm. Longer wheelbase vehicles and rigs with hard tops are likely to have a tight fit in some places and those drivers MUST BE AWARE that some form of body damage is probable. Traveling in a group is recommended so drivers/passengers can assist each other at obstacles with spotting and recovery (winching/tow straps/stacking rocks). Bring gloves, good footwear. Expect this to be a longish day, depending on the number of vehicles in your group.
