The EB48 has been carving out its place as the top 1/8th scale electric
buggy for many years now. Through its history, we have
continually improved on every aspect of performance and
durability. The progression from the EB48 to the EB48.3
evolved through many significant changes, industry firsts, and also
hundreds of fine adjustments. With the introduction of the
EB48.4, we have once again raised the bar and improved on nearly every
aspect of the buggy. This time it took the form of many fine
adjustments, but the leap in performance is our most significant yet.

These changes feed into one desire to manufacture the best handling,
most consistent, most durable, and highest value kit on the market.
We’re confident that our wonderful customers will agree that
we have delivered on these goals.
We have never offered a more predictable yet aggressive steering system
to the 1/8th market. Steering response and durability has been improved
with new bearing supported spindles (TKR8041) and spindle carriers
(TKR8194A). By reducing the wheel offset, we further improved the
geometry, allowing the buggy to get in and out of corners more
consistently in all conditions.
New front arms (TKR8286) now employ the same double-nutted outer hinge
pin (TKR8034) design as the rear arms, ensuring nothing comes loose
during a race, as well as fewer parts in the toolbox. In the
front, shock absorber placement remains the same as the EB48.3. So
expect the same great jump landing and bump handling characteristics.
The new Ackermann plate (TKR8100) and steering bell cranks (TKR8104)
smooth steering response, providing better stability out of corners
without sacrificing on-power steering.
Finishing off the front end are new A and B blocks (TKR8161, TKR8162)
that have a more user-friendly 2.5mm hex cap head screw (TKR1533) to
access the diffs.
New rear arms (TKR8184) and hubs (TKR8040A) have been designed to
accommodate wide rear pivot (TKR8163, TKR8164) hinge pin blocks,
producing increased corner speed and improved forward drive out of
corners while reducing weight transfer. As we did with the
front end, more user-friendly 2.5mm hex cap head screws have been
included for easy diff access. By utilizing a new hub design, the arm
length remains the same, keeping the same great jump landing and bump
(Click image to View Comparison of Wide vs. Narrow Pivot)
The EB48.4 now utilizes front and rear universal driveshafts
(TKR8087). Through rigorous testing, we have found universals
provide the most consistent performance due to their improved bump
handling which allows the suspension components to move more freely and
Internal gear ratio (ring and pinion) has been modified to 3.33:1
(TKR8151, TKR8152), extending battery life while providing improved
power transmission from the center diff to the front and rear
diffs. The new gears are also quieter and more efficient than
The EB48.4 features an all CNC shock package, from the shock bodies to
the internal guides (TKR6146B). 4×1.9 flat/flat
pistons (TKR6165) further refine the damping package and are suited for
just about any track condition. The highly regarded LF (low
frequency) springs (TKR8763, TKR8773) are now included as stock
equipment as well.
Topping off the updated shock system are new CNC 7075 aluminum bleeder
caps (TKR8702) that allow you to build your shocks any way you
prefer. The standard shock build is now an emulsion setup,
but the new caps can be used to build vented and traditional non-vented
shocks just as well (optional bladders required). The new
caps mount to revised shock standoffs (TKR8027) that provide better
clearance between the cap and shock tower.
The original EB48 body was a departure from the wide nitro hand-me-down
bodies. With this release, we have further improved on our
design to offer a body providing more internal clearance, higher
durability, and improved aesthetics.
Aggressive fighter jet inspired styling produces ample steering with
sleek lines followed by three fins to help with high-speed stability
and small spoilers on the rear to increase downforce. Also
featured are several indicated ‘cut’ areas to
improve airflow to the chassis and lower the temperature of your
