What a lifesaver!
Model: 17749N, Model: 17749N
The usual box stores wanted around $150-$200 for a New and or Refurbished starter. The Ezexpreze 17749 was such a great deal and It bolted up nicely to my 1999 TJ with the 4.0 4x4! Its a great replacement, I've had it for about half a year but it starts with ease. I'll definitely get me another one as a backup at this price point!
