### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fits 1996 Polaris Magnum
  

*by A***R on Reviewed in the United States on May 15, 2023*

Bought this to replace the broken one on my 1996 Polaris Magnum ATV.  I bench tested it with a heat gun before installing and it functioned flawlessly.  Smooth install and is working great after a couple months.  Wire terminals plugged right in to the existing wire harness.

Perfect fit but you’ll need tread tape
