The three bolts above are inside the 930E-4 wheel motors. The OEM prices are extremely high, $610.34 for 58B-98-10700 (the one in middle). We are the only aftermarket manufacturer making the three bolts. We have sold over 2,000 pcs of these bolts since 2015 and had no issues at all.

We custom make 58F-30-00080 bolt for a Canadian wheel motor rebuilder. The 58F-30-00080 bolt is inside the 930E-2 wheel motor and is 0.5"shorter than 58B-98-10700. They used to machine it 0.5"shorter. Now we custom make it for the rebuilder.

Our 58B bolts have higher Elongation % than GE’s. This indicates better safety and good low temperature performance.
