I need to change out both knuckle assemblies for my 2008 GEM e4 w/9.21" discs and can’t find the parts anywhere. The Polaris dealers all say Polaris is not supporting the older model GEMs with parts. Any ideas?

I don’t know about the e4 but the elxd uses artic cat atv front knuckles, wheel bearings calipers etc. I think the only difference between the e4 and elxd is the lug pattern but I’m not positive. I don’t know about the brake rotors or the hub that attaches the rotors thought, I think they may be different but not sure.
