Re: GRS1...GRS2...?

GRS stands for Gear Reduction System. With the GRS I it changes the t-case gearing to 4.16:1 giving you a 12% gear reduction in Hi range and 83% in Lo. The GRS II is 4.89:1 thats 18% Hi and 118% Lo. Along with helping to pull bigger tires it also changes your ability to crawl. With stock gearing in the pumpkins GRS I gives you a crawl ratio of about 47:1. GRS II brings it down to 66:1. By changing the R&Ps you can even get these numbers down to 100:1 but unless you plan on doing some industrial strength rock crawling that's way to low for a daily driver.
I run the GRS II and it pulls 31s just fine, and I can keep up with the big kids, who have thousands invested in gears, with no sweat.
