Bilstein 2503B46 0803 H1 - sport or HD?


Recommended Posts

I found a couple of older posts on part numbers, 1 I started on related to the same question for e28s.  The second with the information in the second quote.

 Of course, this is a bit of a guess, but what I see common in the numbers are B46 and an H number.  B46 seems to be common to those described as rear. For the rears,  I see H2 seems to be HD and H1 seems to be Sport. 


"I found a data sheet for Bilstein Shocks dated July 1977.

For the e28, the listing is:

Front:  Street Setting P36-228.  Sport Setting P36-226.

Rear:   Street Setting B46-800.  Sport Setting B46-801.

Perhaps the full part number will help with the cross reference for the new "Performance" parts.




"Bilstein HD (B6)= Old# (F4-P30-0023-H0)  New#(34-000236)  163/76 Parameter
Bilstein HD (B6)= Old#(F4-B46-0803-H2), New# (24-008037) B6  121/57 Parameter
Bilstein Sport front (B8) = Old#(F4-P30-0025-H0)  New#(34-000250)  200/85 Parameter

Bilstein Sport rear (B8)  = Old# (F4-B46-0118-H1), New# (24-001182)  200/60 Parameter"  - 02ManyBimmers
