The RPM True-Track Rear A-Arm Conversion Kit for the Revo
eliminates some of the biggest headaches associated with toe link
rear ends. Rear toe angles are nearly impossible to set
accurately and there isn't a gauge currently made that can
accurately identify whether each individual wheel's toe angle is
set correctly in relation to the chassis. The RPM True-Track rear
end kit completely eliminates the rear toe links, locking in the
rear toe angle at a solid 1.5 degrees per side for a total rear
toe-in angle of 3 degrees. By getting rid of the rear toe links,
we've completely eliminated all rear bump steer! That means the
rear toe angle remains consistent throughout the entire range of
suspension travel, providing superior rear end tracking
regardless of the terrain. Identical to our T/E-Maxx True-Track
Kit, the Revo True-Track Kit retains the stock upper pivot ball
in the new, ultra beefy RPM axle carrier to allow precise camber
adjustments while the lower pivot ball has been eliminated in
favor of a rock-solid 4mm diameter hinge pin that locks in the
rear toe angles for race winning consistency (hinge pin
replacement part 80970). All aspects of the RPM True-Track
Conversion Kit have been beefed up for rugged durability and slop
free movement throughout its range of travel. Additionally, we've
incorporated our oversized bearings into the new RPM axle carrier
design, providing an additional 2mm more bearing contact with the
axle while doubling the bearing load rating and tripling the
igue rating over the stock bearings.
So does all this come at a cost of added weight? The RPM Revo
True-Track Rear A-arm Conversion Kit actually weighs Less than
the stock components it replaces! How much less? 16 grams Per
Side! That's a total of 32 grams or 1-1/8 ounces!
That means you get perfect rear toe angles, added A-arm strength,
bearings that are more durable and longer lasting, an unbeatable
breakage warranty and a reduction in weight! What more can anyone
ask for?
"Bump Steer" Defined: So what is "bump steer"? Bump steer is a
change in the wheel's toe angle caused by the suspension moving
up or down. Bump steer is inherent to the geometry of the
suspension and steering system, and has nothing to do with
turning the steering wheel. The effect of bump steer is for the
wheel to toe-in or toe-out when the suspension moves up or down.
This toe change or �steering" occurs any time the suspension
moves, whether it is from body roll, brake-dive, or hitting a
bump in the road. Bump steer is undesirable because the
suspension is steering the car instead of the driver.
Bump steer is most common on the front end of R/C vehicles due to
the unavoidable use of a tie rod to allow the vehicle to steer.
Vehicles with a toe link rear end such as the Revo also have a
similar a of bump steer in the rear because the axle carrier
isn't locked in a fixed position and is constantly being pushed
and pulled by the toe link as the suspension moves up and down.
This doesn't account for the slop in the rod ends of the toe link
either, which causes even more toe angle changes. See for
yourself. Look down at your vehicle from the top and compress the
suspension. See what happens to the rear toe angle? Each wheel
changes by at least a degree or two, which can be quite
significant. Now imagine that a of movement while your
suspension arms are moving independently from each other and
you'll understand why the True-Track kit is such an effective
tool to dramatically improve suspension performance.
* Included: Our Revo True-Track Rear End Kit consists of two
upper rear A-arms, two lower rear A-arms, two beefy rear axle
carriers, two outer 6x15mm sealed bearings, two inner 12 x 21mm
sealed bearings, two aluminum pivot ball setscrews, two delrin
pivot ball bushing cups, two M3 x 16mm shock screws, two
4mm diameter tool steel hinge pins and enough e-clips to get the
job done (4 minimum).
RPM Recommendations: The RPM True-Track System is designed to
match RPM A-arms (Part No.80212 and No.80215 - Right Side and
No.80222 and No.80225 - Left Side) and Axle Carriers (No.80582
and No.80585 - 1 package needed) currently available for the
Revo. With the True-Track system ed at the rear and a set of
RPM replacement A-arms and Axle Carriers up front, you are
assured the best performing and most indestructible A-arm / Axle
Carrier combination possible!
