## Questions & Answers

**Q: Is this compatible with the SID B A4 models?**
A: My fork is a 2015 SID. From what I can see by reviewing the literature, this air shaft is compatible. I upgraded my fork from 100mm to 120mm. It was pretty simple to do. The videos on SCRAM and youtube are a great help.Follow them exactly and you will have no problems. The extar travel is great!

**Q: Which size is good for reba 100mm to 120mm ?**
A: Only if you also change out the damping system as well.... tried just this and it tops out with a thud.  Reba 100 and this with a spacer is probably good for about 110.

**Q: may i know what is the part number for this item? thank you**
A: The original part number by SRAM is 11.4018.021.000 and the length (from piston top to shaft end) is 222.2mm.

**Q: Can it fit to 2018 sid rlc 100mm? no need change the damper?**
A: You have a charger 2 damper, which is limited to 100mm travel in the SID 32 version. So no, this air shaft will not work for you.
