I have both the FLM and the GH. Quality wise, they are the same. I had to send back an FLM for fitment problems. No problems with the GH ones so far. The good thing about the GH bulks is that they have the easy access feature so you don't have to rip your whole Savage apart to get to the diffs. They also will fit the new XL style larger diff cups, the FLM won't. GH also has a lifetime warranty and I have had great service from them in the past with my Baja 5B parts. The only problem is that they are made in Canada and you have to ship back there for warranty, but they do pay to ship it back to you.
