Carried over from the D817 V2 are steel Universal Joints that are favored by our Team Drivers for improved performance on bumpy tracks, hard anodized machined aluminum 17.5° front caster blocks that have been strengthened for improved durability, and our narrow rear shock tower that has been a favorite of our Team Drivers for its more useful range of adjustment. Revised rear shock length is optimized for the new rear shock tower. New aluminum front linkage geometry spacers replace the plastic spacers for improved bumpsteer geometry, more precise adjustment, less flex, and we revised the screw lengths to accommodate the new spacers.

The E819 has been updated with a new +2mm 7075 aircraft aluminum chassis, and a new 36mm center rear drive shaft for a perfect fit with the new chassis. Standard equipment includes the race-proven HB 4WD system with high strength steel center drive shafts, 43/13 differentials with tough sintered gears, precision machined steel input gears, a heavy duty spur gear, and our popular thin hex hubs. We carried over the two-piece CNC milled aluminum motor mount that keeps the motor securely in place, and allows motor changes without having to readjust the gear mesh. To decrease drivetrain rotating weight the steel spur gear is lightened, as are the diff outdrives and center inputs.
