Bilstein shock sidentification Options

[Montreal914]

Trying to identify what Bilstein shock I have and information is not clear... (IMG:style_emoticons/default/wacko.gif)

Lets start with the back ones as I think this will be easier (maybe). These are yellow and have the 5-6 grooves with the ring allowing to ajust the ride height. P/N is 720 0179 H003. Are these the Heavy Duty, the Sport, or something else? (IMG:style_emoticons/default/confused24.gif) Looks like there is only one option for the rears in yellow with the grooves but they have a different number. Did Bilstein change their numbering scheme?


For the front, I am using 911 3" wedge bolt Boge struts. For this I actually have a selection of 2 sets of Bilstein yellow inserts with part numbers:

F4-P36-0113-H003
052 112 H001 EDIT for typo: 050 112 H001

What to read for both of these two front ones, Regular, Heavy Duty, Sport, other? (IMG:style_emoticons/default/confused24.gif)

Help appreciated. (IMG:style_emoticons/default/smile.gif)

Bilstein replied me back with this information:

Rear: Only one shock has been available for the 914. It is a B6 Performance variant.

720 0179 H003 = F4-B46-0179-H0 = 24-001793

Here is the current product info for it:

Front inserts for 911 3" strut (and maybe others (IMG:style_emoticons/default/confused24.gif) )

050 112 H001 = F4-P36-0112-H0 = 34-001127 --> B6 Performance

Here is the current product info for it:

And the other inserts I have:
F4-P36-0113-H003 = F4-P36-0113-H0 = 34-001134 --> B8 Performance Plus

Based on what was shared here, I will be keeping the B6 front and rear and selling the B8 fronts.
