I hope this is a simple question..
I'm trying to find out what the difference in spline count is on the 914-4 ver 914-6 torsion bars. I have a 1975 914-4 and want to go to 21mm but it seems most suppliers have mixed the 914-4 with the 914-6 and the 6's don't fix on the 4's splines. thank you in advance with your answers..

(IMG:style_emoticons/default/beerchug.gif) 914 torsion bars have 29 splines, 911 have 30. Ask me how I know... I've been shipped 911 bars TWICE. And they are "sided" so be sure you install them on the correct side of the car. They are stamped in the end with "R" or "L". At least the stock ones are... |

From what I have read, there is actually no difference in the L and R torsion bars as they are made. They do, however, "take a set" after being stressed in one direction for years, and reversing that stress tends to cause failures. So getting the "L" on the left side is only important if it came out of the left side... Note that flipping the bar around front-to-back actually has no effect on the direction of stress through the bar, so getting them in the same orientation that way is not critical. --DD |

the torsional load through the long axis of the bar reverses if the bar is flipped front to rear on the same side No. Turning one end in one direction will turn the other end in the *same* direction when viewed from the other end. Flipping the bar (on the same side of the car) will *not* reverse the direction of the stress. (IMG:style_emoticons/default/shades.gif) |
