MitchVerified owneron Hot Racing Aluminum Lock Servo Arm for Traxxas Slash/Stampede 4x4 (25T)

well made and good fit on the servo but it does not work with the slash 4x4. the stock plastic horn drops around 1/8 inch from the servo spline to the screw hole allowing the linkage for the steering arms to sit below the front skid plate. this servo horn rises that same amount and if used in the same manner as the stock horn the steering linkage will be above the skid plate and prone to impacts when running the car. attaching the linkage on the opposite side of the screw hole does not fix the issue either as the linkage then does not have enough clearance to avoid hitting the driveshaft.

Fits the jato 4x4 perfect with a savox servo and hot racing aluminum bellcranks!

Nathan Meironon Hot Racing Aluminum Lock Servo Arm for Traxxas Slash/Stampede 4x4 (25T)

Installed this part on a 4x4 slash with an lcg kit and it works great. No issues with fitment at all and have bashed multiple times since.

What reviewers say

Reviewers agree the aluminum servo arm is well machined and fits the servo spline properly. Opinions diverge on fitment in a stock Slash 4x4. One verified owner reports the arm sits about 1/8 inch higher than the stock plastic horn, which places the steering linkage above the front skid plate where it is prone to impacts, and moving the linkage to the opposite hole causes it to contact the driveshaft. Two other reviewers report a good fit, one on a Jato 4x4 with a Savox servo and another on a Slash 4x4 with an LCG kit, the latter after multiple bashes. Fitment appears to depend on the chassis and kit configuration, and the sample is small.

  • + Well made aluminum construction
  • + Good fit on the servo spline
  • + Fits Jato 4x4 and Slash 4x4 with LCG kit
  • − Sits about 1/8 inch higher than stock horn on a stock Slash 4x4
  • − Linkage can sit above the front skid plate
  • − Opposite-hole linkage placement contacts driveshaft
