Video Overview


The story of the 8IGHT platform is the story of a champion – one that encompasses multiple ROAR national titles in addition to major wins on the international stage. The 8IGHT 4.0 buggy builds on this championship-winning heritage with updates to the suspension geometry and drivetrain layout that make it both easier to drive and tougher to beat.

Revised Suspension Geometry

New suspension geometry makes it easier for drivers of all experience levels to turn faster lap times with fewer mistakes, particularly during brutal, hour-long mains.

Optimized Drivetrain Layout

The engine has been repositioned to reduce front driveshaft angle so more power makes it to the front wheels.

Ball Bearing Actuators

The revised throttle actuator now uses bearings to further improve throttle and brake response. It also features a new brace that prevents flexing during heavy braking.

Large Bearing Spindles and Hubs

Front spindles and rear hubs have been revised to accept a larger 8 × 16 × 5 outer bearing for increased durability.

Revised Chassis Side Guards

The chassis side guards have been updated for a better fit. They also feature indentations for the Velcro body strips.

Large-Footprint Engine Mount

In addition to its new position, the engine mount has been designed with a larger footprint that substantially reduces chassis flex and fatigue underneath the engine when racing on high-grip tracks.

Adjustable Caster Blocks

The adjustable, 15-degree caster blocks make it possible to tune dog bone plunge by changing the height of the spindle.

New Bleeder Shock Caps and Seals

The new bleeder shock caps and internal seals allow for easier rebuilds while using an emulsion shock setup. New bushings that press into the shock cap further improve durability.

Driveshaft and Dog Bone Boots

Molded rubber boots on the universals and center drivetrain dog bones increase U-joint life by holding lubrication in and keeping dirt out.

Redesigned Shock Towers

The machined aluminum shock towers have new camber link and shock location holes that give racers more tuning options for changing track conditions.

Weight Ballast-Ready

The chassis has been designed to accommodate hard-mount ballast weights so it is easier to meet the ROAR minimum weight requirement.

Cab-Forward Body

The cab-forward body moves aerodynamic pressure further forward on the car, which improves steering.

Now Also includes TLR Tuning kit(TLR248000)

Throughout the 2016 racing season Team Losi Racing Team and engineering staff was always evolving their chassis setups on the TLR® 8IGHT 4.0. All of this culminates into the 2017 TLR Tuning Kit for the 8IGHT 4.0 buggy. Using our racing team and development staff we have further improved the 8IGHT platform for a more reliable and faster race buggy. The key improvements allow the buggy improved the handling on bumpy tracks, enhanced braking, and improved durability. This TLR tuned kit allows the consumer to purchase all of the same parts that were used by our race team at the IFMAR 2016 World Championships and into the 2017 racing season. Here is why we came out with each part.

Ultralite Chassis
Lighter weight and more flex for a more responsive vehicle in bumpy conditions. With this chassis the gear box now has the ability to move 3mm forward, in conjunction with the included offset rear adjustable hinge pin braces, to give the rear end less bone angle for less mechanical bind which allows the car to adapt quicker to rough terrain.

Heavy Duty Brake Pads and Disk
Completely new 100% CNC design now keeps the brake disc true with the out drive and minimizes the possibility for it to skew. Now the brake plates have material glued in for a much more stronger and consistent brake feel after a hour long main event.

Front and Rear Universals
Reduce the mechanical bind in the drive train to allow the suspension to adapt to the surface quicker.

Aluminum Spindles
New front aluminum spindles are required with the front universals to allow for the correct bearing depth. These also add significant durability to the most vulnerable part of the car if it comes under heavy impact.

Gen II Wing Mount
This new wing mount allows for the new polycarbonate or the standard plastic wing to be used by allowing 5-40 srews, aluminum support washers and nuts to secure it to the mount, but as an added feature you can install the new ( included) machined post to continue to use the body clip method for attaching the wing to the mount.

Polycarbonate Wing
A new polycarbonate high down force wing is much lighter than the traditional composite wing, when installed it brings the buggys center of gravity creating a stable buggy around high speed tracks. This wing also generates more down force for more rear traction, but can be tuned out by simply opening holes to reduce the drag.

Magnetic Wheel Nuts
The new TLR wheel nuts include a steel screw and nut in the center which holds to our new magnetic TLR wheel wrench (wrench not included). This makes tire changes during main events much faster and minimizes risk of loosing a nut during a tire change.

High Downforce Body
This body is an all new design that compliments the new polycarbonate high downforce wing, while the cab and front side pods have more surface area for greater front traction and steering. The body, in combination with the wing, provides a more stable buggy.

Clamping Servo Saver Nut
This new nut directly replaces the stock nut and now uses a clamping feature via a screw. This removes the chances of the servo saver nut backing off during long main events.
