Monarch Service Kit Basic 2011 Monarch RT3/RT/R

"Unfortunately, this wasn't the correct service kit for my shock. Before ordering, input the serial number into the SRAM service centre. There are three variants of the Monarch R shock (A1, C1, and D2). If I've understood the SRAM spare parts catalogue correctly, this kit is for the A1 variant. I have the C1 variant, which means I needed the '11.4118.038.000 REAR SHOCK SERVICE KIT - FULL SERVICE MONARCH'. I re-assembled my shock with a combination of the 'O' rings contained within this service kit that were compatible (i.e. the same dimensions) and the existing 'O' rings. TF tuned did clearly state, in their advertisement, the kit is intended for 2011/2012 models. So, the mistake was mine for not double checking compatibility on the service section of SRAM's website. Despite this, the re-assembled shock is buttery smooth and the 'O' rings that could be used were compatible. I wouldn't recommend this, though. "
