Hey everyone, although it will still probably be a while, I'm starting to look further into my regear & rear axle swap. I have found 4.56 gear kits from Yukon gear and axle over at summit racing for around $250, and then I've found cheaper options such as a brand name of Motive Gear, and the MUCH cheaper options like the one in this link.
http://www.ebay.com/itm/CHEVY-GM-8-6-10-Bolt-Gears-Ring-Pinion-4-56-NEW-/391417549610?_trksid=p2141725.m3641.l6368I know practically nothing when it comes down to metal strengths and the different strength treatments/quality. The cheapest gearset (in the ebay link above) says "Manufactured with 8620 Heat-Treated Material" and "Premium Quality Gears" all over it. But I don't know what "8620 material" means in this context, and of course its ebay....
When I think of anything driveline/powertrain, I automatically assume the most expensive is the best quality and best option. Is there a massive difference between these gears that I should spend the extra 150+ bucks on? Or would I be just a good off getting a set from Motive gear or possibly even an Ebay seller?
Thoughts and opinions please. Thanks!
