While the product feels decent, the horn adapters are junk and HR refuses to contact me on the issue so it’s basically useless to me. Don’t buy this unless you want a headache

Horn adapters stripped immediately. Moreover the spring is not smooth and does not center correctly. Makes the car drive really bad

This thing looks and feels like quality but it is actually just garbage. The adapter stripped out first run. I usually like hot racing products but they dropped the ball on this one. Do not waste your money

Was will to take it apart and polish it and grease it but the adaptors don't fit WAY to tight

Seth Kummeron Hot Racing Aluminum CNC Heavy Duty Servo Saver w/Heavy Spring Tension (Black)

The spring is too large for aluminum casing and because it’s harder metal it gets stuck and does not return to original alignment. I also noticed the spring sticks making it hard to find center steering as I changes every time you bump the front wheels on anything. Again it’s because the aping gets stuck and can’t return to center leaving play witch only gets worse every hit you take. Horrible product do not buy and please leave a review so it’s removed as it’s overpriced as well.

What reviewers say

All five reviews are one-star and describe the same main problem: the horn adapters strip or fit too tightly, with at least one reviewer noting the issue occurred on the first run. Several reviewers also report the spring is not smooth, sticks, and fails to return the steering to center, leaving play that worsens with impacts. Some reviewers say the build quality looks and feels good, but they consider the product unreliable. Three reviewers are verified owners and two are not. One reviewer says the manufacturer did not respond to their issue. All reviews refer to the Black variant. Overall sentiment is strongly negative.

  • + Looks and feels well built
  • + Solid aluminum CNC construction feel
  • − Horn adapters strip or fit too tightly
  • − Spring is rough, sticks and does not re-center
  • − Steering play worsens after impacts
  • − Manufacturer did not respond to a reported issue
