looking to get some 4.88 gears for a decent price with carriors and overhaul kits ,. so far ive ordered majority of my parts from RC , was wondering if i should just stick with them , considering the packages are priced in pairs , i already talked to them to make a gear package for the axles i have , and the price with carriors is 664 approx before shipping to canada . also they give me a 10% discount due to frequent activity? any suggestions?
