TUNING TIPS FRONT CASTER This is the angle of the front hub from vertical when viewed from the side of the PRO-MT 4×4. It is adjusted by swapping or changing the combination of the 1mm and 2mm spacers on the front upper hinge pin. (see circled items above) The PRO-MT 4×4 has 10 Degrees of front kick-up with adjustable front caster angle from +10o to +20o. The stock setting is +15o of caster.
CENTER DIFFERENTIAL SHOCK OIL & LOCATION Stock oil included in the center diff is 100,000 cSt. Stock shock oil for the PRO-MT 4×4 is 40wt. There are two shock mounting locations on the shock towers and two on the lower arms. When using 1:8 buggy motor systems with 4S Lipo power, you may find that the center diff is sending too much power to the front wheels when the truck wheelies. To provide more balanced wheel speed front to rear with extreme power systems, use heavier diff fluid in the center diff.
OPTION TIRES SAND PAW 2.8" PRIME 2.8" TRENCHER 2.8" A must for sand and snow conditions to throw up huge roosts! If you will be using your PRO-MT 4×4 on the street or for speed runs, the Prime is your best option. Award-winning all-terrain tire works on any surface as an alternative to the stock Badlands MX28 tires.
