Twin stick shifters offer the ability to switch between High range and Low range independent from the selection of 2WD or 4WD. This can be particularly useful on high-traction surfaces when the rig has an automatic front locker. A twin stick makes tight turns much easier, allowing rear-wheel drive with the slow speed control of Low range. By having 2-Lo, the front axle is relieved from undue stress, and four-wheel drive can be re-engaged, even while moving, by just throwing one lever. In order to use the twin stick, the transfer case must be partially disassembled and the interlock pin removed from between the shift rails.
FROR was the first company to manufacture a twin stick for Toyota transfer cases. The shifter is 100-percent bolt-in and available in custom lengths to accommodate body lifts. The FROR unit is a completely sealed assembly that is rebuildable and made of all-new parts.
The Marlin Crawler twin stick features a low-profile billet base. Its compact design is great for low-clearance applications, and the vent breather is tucked below the billet casing on the top of the baseplate. This simple design has no attached bolts or brackets that might become loose over time.
Once you have invested a large amount of time and money into your transfer case, it would be wise to protect your investment. Luckily, there is a variety of crossmembers that provide increased protection (and ground clearance) for your new transfer case(s).
All-Pro manufactures crossmembers for single case or dual case applications that feature integrated skidplates. These crossmembers are made of mild steel square tubing and fully welded. The All-Pro crossmember offers 1-3/4 inches more ground clearance than the stock crossmember and bolts to the stock frame mounts. All-Pro's crossmember comes in bare metal ready to paint.
BudBuilt offers crossmembers for single or dual case applications and are available to accommodate any amount of drivetrain lift (specify when ordering). The BudBuilt piece bolts in place of the stock crossmember but provides almost 2-1/2 inches more clearance, as well as better protection than stock. Constructed out of a single piece of laser-cut, hot-rolled, pickled-and-oiled 3/8-inch steel, the BudBuilt crossmember is smooth enough to allow the vehicle to slide over obstacles. Bud's dual transfer case crossmember allows for the use of two stock rubber mounting brackets to limit movement in the drivetrain.
FROR builds a crossmember that connects to the back of the transfer case and sits between the framerails. By mounting from the back side of the transfer case, driveshaft interference with the front driveshaft on dual-case-equipped trucks is eliminated. The crossmember will fit with single or dual transfer cases, however some welding is required, and it will not fit IFS trucks due to interference with the torsion bar mounts. The mounting allows the user to raise the transfer cases as high as desired and leaves very little protruding below the frame. The 3/8-inch-plate FROR unit also provides increased rigidity compared to the stock crossmember, resulting in fewer broken motor mounts.
