The following gear ratio chart shows the available combinations with
optional spur gears, clutch bells, and two-speed gear sets.

Tuning The Sealed Gear Differentials

Revo’s front and rear gear differentials allow the left and right wheels to
spin at different speeds while turning so that the tires do not scuff or skid.
This decreases the turning radius and increases steering performance.

The performance of the differentials can be tuned for different driving
conditions and performance requirements. The differentials are filled with
silicone differential fluid, and are sealed to maintain consistent
long-term performance. Changing the oil in the differential with either
lower or higher viscosity oil will vary the performance characteristics of the
differentials.

Changing to a higher viscosity oil in the differential will reduce the
tendency for engine power to be transferred to the wheel with the least
traction. You may notice this when making sharp turns on slick surfaces.
The unloaded wheels on the inside of the turn have the least traction and

tend to spin up to extremely high rpms. Higher viscosity (thicker) oil causes
the differential to act like a limited-slip differential, distributing more equal
power to the left and right wheels. Revo will generally benefit from higher
viscosity oil when climbing, rock crawling, or racing on low traction
surfaces.

Note:

Heavier oil will allow power to be transferred even with

one or more tires off the ground. This can make the vehicle more likely
to overturn.

From the factory, both the differentials are filled with SAE 30,000W
viscosity silicone oil. Only use silicone oil in the differentials. Traxxas sells
SAE 10,000W and SAE 50,000W viscosity oil (see your parts list). The
differentials have to be removed from the vehicle and disassembled to
change/replace oil.

Installing the Long Travel Rockers

Use the exploded views included with the model to aid in the installation
process. All of the rockers have labels identifying their proper location; RF
(right front), LF (left front), RR (right rear), and LR (left rear).

Note:

The

exhaust system must be removed to access the rear rocker arms.

1. Remove shock absorbers

Remove the screws that secure the shocks to the chassis shock mounts,
and to the rocker arms.

2. Install long travel shock springs

Replace all four of the 90mm travel shock springs with the four 120mm
long travel shock springs. The front shock springs are indicated by a silver
dot, and the rear shock springs are indicated by a blue dot.

3. Install long travel rockers

Replace the 90mm travel rockers with the long travel rockers by removing
the four 4x6 buttonhead cap screws from the rocker pivot posts. Remove
the 5x11 ball bearings from the rockers. Install the same 5x11 ball bearings
in the long travel rockers. Secure the long travel rockers to the pivots with
the same 4x6 buttonhead cap screws.

4. Locate push rods

Make sure that all four of the suspension push rods are located
and secured into the middle position (marked LT) on the lower
suspension arms.

5. Reinstall shock absorbers

Reinstall all four shock absorbers back into their respective locations.
