Hell I say go to Autozone or NAPA or whereever if you arent making huge HP.

Ive seen 400whp Drag cars make it down the 1320 numerous times on stock axles. Some get lucky, some dont. One things for sure, unless youre making solid power, I wouldnt worry about getting anything other than OEM or Autozone/Napa/Pep Boys, etc. Id use them until I had a frequent snapping issue with them.
