NB48.4 1/8th 4WD Competition Nitro Buggy Kit

The NB48 has been carving out its place as the top 1/8th scale nitro buggy for many years now.  Through its history, we have continually improved on every aspect of performance and durability.  The progression from the NB48 to the NB48.3 evolved through many significant changes, industry firsts, and also hundreds of fine adjustments.  With the introduction of the NB48.4, 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.

NB48.4 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 Rear Bulkhead Brace System
  • New CNC 7075 Aluminum Bleeder Shock Caps (emulsion, vented, non-vented)
  • New LF (low frequency) Shock Springs
  • New Fighter Jet Inspired Body Design

Front End

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 NB48.3. 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.

 

 

Rear End

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.

The NB48.4 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 efficiently.

Internal gear ratio (ring and pinion) has been modified to 3.25:1 (TKR8151B, TKR8152B), extending run time 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 ever before.

The NB48.4 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.

Body

The original NB48 body was a departure from the typical wide nitro 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 sides to increase downforce.  Also featured are never-before-seen changes to improve refueling access. A molded recess has been specifically designed to improve tank pull and fuel gun access while reducing internal fuel splash on critical components such as the brakes, engine and electronics.
