Some people have trouble with them,some don't as stated above.To some even a little trouble is not worth it. OEMs are good and I had no trouble.For me its OEM.
It's strange how everyone is all over the spectrum of OM vs Sierra. To me the $100 extra is alot of money, but I don't want to sacrifice. Has anyone had a Sierra product fail or do they just strictly use OEM because?
I prefer oem, for bellows kits and shift cables. Sometimes I'll use sierra for small easy to get to parts. I will not use sierra for anything electrical, to many issues in the past.
