Team Losi Racing 8IGHT 3.0

There has been a lot of talk about the Team Losi Racing 8IGHT 3.0 today. Here are the improvements we've made on the 8IGHT 3.0. 
The front suspension is full redesigned with new front caster blocks (15 degrees), spindles, and front arms. The spindles are higher on the caster block creating less front dog bone plunge therefore allowing for better bump handling. We've also revised the droop screw system to eliminate chassis galling with a large headed screw that touches the chassis instead of the traditional set screw. 

The Ackerman links now have 4 x 8mm flanged bearings allowing for ultra smooth steering. It is now possible to full tighten the shoulder screws with no binding issues


The 8IGHT 3.0 has a substantial amount of more travel. The front shock tower is taller with longer front and rear shocks. 

Onto the shocks, they are now 16mm bore with machined pistons, guides and bushing guides offering near perfect tolerances for excellent shock action. The bores of the shocks have been precisely machined allowing for even smoother shock action and decreasing any bind issues that one may experience under heavy impacts. The shock shafts are now TiCn coated. The new coating is ultra smooth and extremely durable. Just like the shock shafts, the hinge pins are treated with the same coating. The springs are new and tapered to decrease the spring cups from becoming ejected during crashes.

Gen III Radio-Nothing new there but definitely an added feature to improve servo life.

Chassis-Updated chassis with increased milling that lightens the 4mm 7075 T6 aluminum chassis.

Myriad of option parts included-Front and rear adjustable hinge pin mounts, lightweight 48T spur gear, lightweight outdrives in all three differentials, aluminum bearing inserts, and +1mm rear hexes.

Center Drive System-We changed from the CVA style center driveshaft’s to a dog bone system. This decreases friction in the drivetrain that increases acceleration, improves runtime and decreases front center dog bone wear. We also added brake caliper springs to the brake posts to ensure full disengagement of the brake discs under acceleration.

The shock towers are the traditional 4mm milled 7075 aluminum shock towers with optimized camber link and shock positions. 

Rear arms have been updated to accept the rear dog bone drive shafts that are advantageous on bumpy tracks.

Body-New cab forward inspired body with center fin for added side bite.

Wing-A completely new molded wing with larger endplates and center fins aid in increased stability and rear traction.

Wing spacers-We now offer three different wing positions via spacers. The stock wing location, .250" back, and .500" back. By moving the wing back creates more rear grip.

Wicker bill-Molded wicker bills in two different sizes. .250" and .350" offer more stability and increased off-power steering.

New dome style wheels-The new TLR wheel offers improved clearance with a revised dome style look. The wheels are stiffer than the current Losi 8IGHT wheel. We now include 4 white wheels and 4 yellow wheels.

We have also updated the internal diff gears that provide smoother diff action.

As you all can see we have definitely increased the feature set on the 8IGHT 3.0. The car handles substantially better over the 8IGHT 2.0. The 8IGHT 2.0 is definitely a drivers car and is known to play tricks on the best drivers and cause unexpected mistakes. At TLR, we put a lot of focus on the drivability of the chassis while doing our best to keep it fast. I am confident that once the 8IGHT 3.0 reaches the hands of racers across the world you will see all of the work and development we have invested into the 8IGHT 3.0.

We hope you enjoy the Team Losi Racing 8IGHT 3.0 as much as we've enjoyed improving it.
