I've got a 98 ls1. I broke a push rod and it fell down into the reluctor wheel area and messed it all up. I ordered GM performance part # 12559353 which is suposed to work on all gen III ls1 and ls6. I noticed that the spacing in the teeth is different than the original fatory reluctor wheel. The # of teeth is the same and even the proportioning of the spacing is the same. I was wondering if any body has had any probs with the Performance parts reluctor wheel?

Thanks Mike

 

Shouldn't be an issue. My 24x wheel looked different between my LS1 & LQ9 crank but worked just fine on the same PCM.
