I am looking to change my gears in my 82 K30. It now has 4.10's and I want to go to 4.88's. I am looking to get the complete package deal with 4WheelParts. They show the D60 gears are from Dana/Spicer and the rear 14FF are Genuine Gear. I have heard positive stuff about the D/S, but what does everyone think of the GG? I have had gears from 4WP before, but that was like 8 or 9 years ago. I plan on installing these ratios with a Detroit Locker in the rear and a Pow'r Lok in the front. The Pow'r Lok is from Precision Gear. Anybody have opinions?
