I need to replace my DDC rear shock but don't wanna go to Ohlins at the moment.. I've been looking at ebay to find a suitable replacement within my budget. Here's the dilemma - my 2015 RR bike was manufactured in 11/14 and the part number on the Sachs shock is 33548548838 and I've been looking at the part number on realoem.com and it has been replaced with Part No. 33548561412. Is it okay to install the newer part even though it's a different part number. Realoem.com says that the newer part supersedes the older part number and I can't find any place that sells the same Sach's shock with the 8838 part number.
