1/10-Scale Comp Crawler
Incorporating real engineering elements from full-size rock
crawling competition, the 1/10 Comp Crawler Race Roller represents the pinnacle
of RC rock crawling design. The Comp Crawler offers several innovative features
including a DIG transmission, solid axles with a worm gear drive, front and
rear locking differentials, a 4-link suspension and so much more.

COMPACT FRONT & REAR LOCKING (DIG) CENTER TRANSMISSION ALLOWS THE CRAWLER TO
OVERTAKE OBSTACLES WITH EASE
FRONT AND REAR SOLID AXLE WITH WORM GEAR DRIVE
FRONT AND REAR LOCKED DIFFERENTIAL PROVIDES FULL TIME 4WD
4-LINK SUSPENSION MINIMIZES REAR AXLE SWING,ALLOWING FOR MORE PRECISE HANDLING
3-PIECE 2.2" BEAD LOCK WHEELS WITH ALUMINUM OUTER RINGS
2.2 LOSI ROCK CLAWS TIRES WITH FOAM INSERTS
4" ALUMINUM THREADED SHOCKS WITH TITANIUM NITRIDE (TiNi) SHAFTS ALLOW THE
SUSPENSION TO ARTICULATE WITHOUT ANY BINDS
DURABLE CV FRONT AXLE SHAFTS ALLOW FOR INCREASED STEERING RANGE
TWIN VERTICAL PLATE CHASSIS WITH ADJUSTABLE SHOCK MOUNTS
ZERO ACKERMAN STEERING PROVIDES CLASS LEADING PERFORMANCE WITH 45 DEGREES OF
ALUMINUM UPPER AND LOWER SUSPENSION LINKS FOR ADDED STRENGTH
RACE ROLLER CHASSIS IS PREASSEMBLED; SIMPLY
ADD ELECTRONICS, PAINT AND GO
A specially designed 4-link suspension setup is used in combination with the
twin vertical plate chassis, reducing axle swing and eliminating side-to-side
movement for increased steering and maneuvering precision. 7mm diameter
aluminum lower links are hard anodized and triangulated to the center of the
chassis for better balance front to rear when the suspension starts to twist.
Zero Ackerman Steering
Designed with the demanding conditions of competition rock crawling in mind, the
steering system on the Comp Crawler provides precise control as well as class
leading performance with 45 degrees of steering throw. The front caster blocks
feature 10 degrees of caster and the spindles are attached with heavy duty
steel king pins. The steering geometry also allowed Team Losi Racing engineers
to raise the main steering link closer to the axle housing, giving the Crawler
additional clearance when approaching obstacles.
Just like full-size crawlers, the 1/10 Comp Crawler utilizes functional bead
lock wheels with aluminum outer rings. The functioning bead lock allows for the
tires to maintain more contact and traction, while the aluminum outer rings
provide evenly distributed pressure for unbeatable tire mounting.
Losi Rock Claws
Losi equipped the 1/10 Comp Crawler with National Champion Rock Claws 2.2 Tires,
giving you the ability to aggressively attack uneven and rocky terrain. The
creative multi-edged tread design enhances traction by simultaneously gripping
in multiple planes on uneven surfaces, much like that of fingers gripping a
rock. The large lug design also helps in cleaning itself from mud and dirt
giving enhanced traction in these types of conditions.
Aluminum Threaded Shocks
The high performance, durable 4" aluminum threaded shocks provide the suspension
travel needed for optimum articulation over any terrain or course, and the
Titanium Nitride (TiNi) shock shafts ensure smooth, predictable operation
Aluminum Suspension Links
Alloy lower suspension links with captured ends offer exceptional durability and
hold, preventing disconnection over any terrain. The links also add to the
realistic look of the Comp Crawler by emulating the appearance of full-size
Telescoping CV Driveshafts
By combining the solid axle design with CV axle shafts in the front end, the
Comp Crawler has an unparalleled combination of durability and maximum steering
throw, ensuring the ability to maneuver over, out of or around the tightest
courses and biggest obstacles.
Adjustable Upper Shock Mounts
Multiple shock mounting positions allow the user to adjust droop and angles
without having to do any significant disassembly.
The 1/10 Comp Crawler's Twin Vertical Plate (TVP) chassis offers unbeatable
stability and rigidity in a durable, lightweight design. The result is
confident handling over any terrain and outstanding suspension articulation.
And Team Losi Racing has gone one step further, by offering this innovative
crawling chassis pre-built and tuned right out of the box. All you have to do
is add the electronics of your choice.
Dig Center Transmission
The 1/10 Comp Crawler is the first crawler in the industry to offer both a front
and rear locking DIG center transmission. This feature allows the front or rear
drive axles to be disengaged to act as a steering brake, thus allowing the Comp
Crawler to overtake tricky obstacles with ease.

Solid Axle With Worm Gear Drive
The 1/10 Comp Crawler features a front and rear solid axle with a worm gear
drive. The worm gear functions as a braking device while the power supply is
idle, however when power is supplied the efficient design of the worm gear
eliminates "torque twist" which commonly occurs in shaft driven rock crawlers.
The heat treated steel worm gear also utilizes a smaller gear assembly, thereby
maximizing ground clearance under the axle housing.
Multi-Link Suspension Design
The 1/10 Comp Crawler features a 4 link suspension layout. With this 4 link
design the axle has almost zero side-to-side axle swing, thus providing
constant and precise suspension movement. This means that when the Comp Crawler
travels over an obstacle you will experience nearly zero axle swing or wheel
45 Degree Steering Angle
The 1/10 Comp Crawler features a steering geometry with zero Ackerman steering,
which allows the Comp Crawler to have a class leading 45 degrees of steering
angle. The Comp Crawler utilizes RCD CV style drive axles with heavy duty 4.5mm
axle shafts to continue to put the power down to the wheels while turning at
this extreme angle.
