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.
EB48.4 New Features
- New CNC 7075 Chassis with Improved Wear Characteristics
- Revised Steering Geometry and Ackerman Plate
- Bearing Supported Spindle/Carrier Design
- Revised Wide Rear Pivot Suspension Geometry
- Revised Ultra Efficient Drivetrain with New Universal Driveshafts
- Revised Internal Gear Ratio for Improved Efficiency
- CNC 4×1.9 Flat/Flat Delrin Pistons and CNC Delrin Guides
- New CNC 7075 Aluminum Bleeder Shock Caps (emulsion, vented, non-vented)
- New LF (low frequency) Shock Springs
- New Fighter Jet Inspired Body Design
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.
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 handling.
