SECTION 9: SETTING UP YOUR X-FACTOR2 FOR ROCK CRAWLING
One thing that a lot of people like to do with
their X-Factor2 is rock crawling. Like full-size
rock crawlers, the X-Factor2's suspension,
drivetrain and overall chassis design make
it perfect for rock crawling. In this section
we'll list some of our proven setup tips that
will transform your X-Factor2 into a rock
crawling machine that knows no bounds!
We also suggest that you experiment with your own setups that may suit your
particular rock crawling site. Most of all, have fun!
OUR SETUP SUGGESTIONS FOR ROCK CRAWLING
●
The toe angle of both the front and rear tires should be 0 degrees.
●
The stock differentials are packed with lightweight differential grease. For rock crawling you want the differentials much tighter with
very little "action". You can achieve this by disassembling both front and rear differentials and packing them tightly with heavy
differential grease, or even better, clean out the stock differential grease and refill the differentials with heavy silicone differential oil,
such as Associated 300,000Wt (300K) differential oil.
●
Using softer compound tires will give your truck better grip over rock crawling surfaces than the firmer
compound stock tires. The IMEX brand wheels and tires are popular among rock crawlers. These
wheels and tires will also give your X-Factor2 a wider stance that make it more stable.

If you use IMEX wheels on your X-Factor2, the XTM Racing Axle Adapter
Set (P/N 146110) must be used, too.
●
The suspension should be set very soft. You might try using 40Wt shock oil in the shocks and either
1.4mm Blue shock springs or even softer 1.3mm Red shock springs.
●
You should definitely remove the two torsion bars from the suspension, so that the suspension can articulate as much as possible.
●
For better low-speed crawling, you may want to change the stock 15T clutch bell to the XTM Racing 13T clutch bell (P/N 149525).

If you use the XTM Racing 13T clutch bell listed above, you will also need to use these XTM Racing Flanged Ball
Bearings (P/N 149559).
●
You may want to tighten the slipper clutch slightly. It's important to get as much power to the wheels as possible.
●
By removing the gear box rods and adding washers between the ends of the rods and
the ball ends, you can extend the wheel base of the truck by almost 1/2". The extended
wheel base will make the truck slightly more stable for rock crawling.

If you extend the length of the gear box rods, make sure you extend
them equally in sets (i.e., extend all four rear gear box rods and/or all four front gear
box rods equally. This way, you ensure that you keep the chassis square.
●
By removing the solid cantilever link rods and replacing them with shocks, the ride
height of the truck will be increased and the suspension will articulate even more.
Overall, the suspension will be softer, too. Even better for rock crawling. We suggest
purchasing the same set of shocks that are already installed on the truck. They are a
perfect fit.
