Includes:

  • (1) steel 34T ring gear

Requires:

  • Two sets per vehicle
  • Reuses Traxxas TRA7082 internal spider and carrier gears, as well as the output shaft seal and outdrives from the original differential
  • Installation may require optional shimming using the included shims for proper gear mesh. The gears should run freely without too much play and without binding.
  • Use removable thread lock (e. g. blue Loctite) on carrier screws

Comments:

  • Does not include inner differential gears.
  • Replaces Traxxas 7079 ring and pinion and 7080 carrier cover plates (except for the output shaft seal)

Hot Racing 1/16 Traxxas Steel Helical Spiral Gear Set w/Aluminum Cover Plate
This is a great gear set for the 1/16 erevo vxl. I have not broken this one like the stock diff and it also gives me a little more speed and torque. I highly recommend this product regardless of the price it is worth every penny.

Hot Racing 1/16 Traxxas Steel Helical Spiral Gear Set w/Aluminum Cover Plate
Amazing differentials for the 1/16 E-Revo VXL. The stock diffs would strip out after about 2 days of 3s LiHV racing. These diffs have not stripped or clicked at all. They are extremely quiet and fit perfectly into the Traxxas case. They are on the expensive side, but you get what you pay for. They are built differently than the stock differentials, but I figured it out and they work as expected.
Update: This differential somehow survived smashing into a curb at 50+mph. My transmitter spring broke, and my throttle didn’t return to zero, and my souped up mini E-Revo smashed into a curb at 52mph. All it broke was my plastic center driveshaft…..no clicking though. Buy this, you won’t regret it!
