This is a much have item for any TRX4 The original plastic that comes with the truck stripped out on the second battery pack this should be standard on the TRX4 from Traxxas but for the price it should be ordered when you order the truck these are awesome

Must have upgrade for the TRX4. This is the first and only upgrade I’ve done to my Defender. Great price and fast shipping from Amain.

Identical to the factory plastic one but metal. There are semicircular indentions in the servo mount that allow for all the available travel of the horn, i cant imagine any other horn being able to squeeze the most out of the steering like this one.

Simple, great fix. I'm really unclear why any TRX4 doesn't ship with these metal servo horns. New to the scene with a TRX4 and TRX6. The plastic stock servo horn stripped quickly on both of the trucks. Luckily, I had ordered these and have had no problems since.

A must for TRX-4 and TRX-6 owners. The stock horn strips very easily.

What reviewers say

All five verified reviewers rate this metal servo horn 5/5 and report that it replaces the stock plastic horn, which reviewers say stripped quickly, including after a second battery pack and on both a TRX-4 and a TRX-6. Reviewers describe it as identical in shape to the factory part but made of metal, and one notes it allows full steering travel with the servo mount's semicircular indentations. Reviewers say no problems have followed installation. Several mention the price and fast shipping from a seller, and one questions why the part is not standard equipment. The reviews are uniformly positive and short on detail about durability over long periods.

  • + Metal replacement for stock plastic horn
  • + Reportedly does not strip
  • + Full steering travel
  • + Good price
  • − Stock part not included as standard
  • − Limited long-term durability reports
