Converted our 2010 GMC Yukon XL from GU4 3.08 ratio to K5L 3.42 ratio so it could tow more. We are selling what came off when we switched, mostly differential parts. These are 3.08 ratio parts - thus the better gas mileage than with 3.42 or higher towing packages. Pictures are what we have. Parts include radiator, 2 fan motors, 2 fan blades, front ring/pinion, rear ring/pinion, front diff case assembly, rear diff case assembly. Parts have 16,626 miles on them. Dealer price on parts is $4,021.53. $1250 OBO plus shipping. Will consider reasonable offers. Selling as one group please. Parts will fit GMC Yukon, Yukon XL, Chevrolet Tahoe, and Suburban.

Happy to answer any questions you may have, please send a message. Thanks.

 

Lower the price to $1150. Please PM me with questions and/or reasonable offer.

 

Price now $1000. If you have experience selling these sorts of parts, please PM me as I'd like to be reasonable but just don't know what these typically sell for, thanks.
