Connecting rod weights
« on: 17.10. 2020 14:27 »
Got a set for new R&R connecting rods, $450 froma US vendor..On my triple beam scale, the weight is 390.5 grams. The original A10 rod is 383 grams.Not enough difference to worry about in my opinion . I did not weigh big and small ends separate but should be very similar
   Other photo shows the R&R on top of the stock rod...stock rod is slightly larger...
  If made from identical aluminum, the stock rod forged into shape should be stronger than
a rod  machined from a forged billet..But its not relevant because there's no way to make a comparisons without knowledge f the aluminum used
 Does anyone know the weight of the Thunder Rods?

some info on weights here for SJ rod weight, to compare you need to know whether bolts nuts and shells etc are included or not.
