I've got a top end overhaul coming this summer for my truck, and wanted to compare some prices online. I was shocked to see Beck/Arnley parts are less than half OEM! Add shipping and it's still cheaper: Intake Valve (6): $23.22 (OEM: $81.27) Exhaust Valve (6): $34.14 (OEM: $81.27) Intake Valve Guide (6): $7.20 (OEM: $25.25) Exhaust Valve Guide (6): $7.44 (OEM: $25.25) Timing Belt Tensioner: $11.52 (OEM: 25.77) Add $43.07 International Priority shipping to Kuwait and the grand total is $126.59 as opposed to $238.83 to get OEM parts locally. Long story short, should I just buy the Beck/Arnley parts? Are they of lesser quality than OEM to be priced so differently? Any input will be muchly appreciated, thanks!
