Anyone know the diffs between early (pre 74) and late 911 struts?
I know the nut on the spindle is a different size. Are the hubs interchangable? The bearings are the same. |

Only very early hubs with solid rotors are different.
AFAIK all 911 hubs up to ยด89 are interchangable. |

I just went through this...
The early struts have a different (smaller) locking nut on the spindle The early hubs will fit over a later strut, but the later locking nut (that you need with the later strut) is too big to fit the opening of the hub (but you can machine it to make fit) This thread has some good info... |

Basically there are 3 types of 911 strut, the very early one where the balljoint mountswo the bottom of the strut 3 with bolts, the next generation strut clamped the ball joint in place, the later iteration held the ball joint with a wedge bolts.
There are also differnces in struts depending whether they cam with Bilstien, Boge, or Koni inserts. The later struts used a coarse thread pinch nut, compared the the earlier two version fin thread pinch nut. the bearings and races are the same though. One caveat, if using a early hub on with late style struts/pinch bolts, you may have to open the hub a bit on a lathe to clear the pinch bolts. There is the fourth type of stut also, the raised spindle/theaded body RSR type |
