Yukon Gear & Axle Dura Grip Limited Slip Differential Positraction, 34 Spline, Compatible with 9.75" Ford Axle, YDGF9.75-34-1

Just got the 500 mile break-in on it and so far I love it. It’s great performance and provides excellent traction and if I had to do it over, I’d buy another one.

Replaced the open diff on my 97 Cougar with this in 2021, and I’m writing this 3 years and about 15k miles later. Besides the car itself, this is possibly the best purchase I’ve ever made. No more one wheel peels, one tire fires, whatever ya wanna call it. Now it has better grip and gets sideways when I want it to.I used the Yukon friction modifier with Valvoline brand diff fluid and it’s super quiet. Sometimes I hear a little chirp, but over the sound of the engine it’s barely perceptible.I have been pretty hard on the car since installing this, and it has held up fantastic. I’ve done plenty of smoky burnouts, donuts and drifting (mainly on wet pavement because car is kinda slow), and I haven’t had any issues.My only regret is not having the shop install 3.73 gears while they were in there. Finding a shop to install it was a bit of a hassle; it would have been smart to make the appointment before ordering. But all is well now.Smoke ‘em if you got em 🤙🏻

Can’t beat the price and the quality highly recommended

The rear end of my 2007 yukon xl tragically exploded with a car full of kids. This vehicle is my daily grocery getter and only vehicle we own that van haul all our kiddos. We were stressing about whether to purchase all the needed parts separately at Advance auto, or buy used. My husband has lots of experience with mechanics, but had never changed an entire rear end and found the task daunting. We took a chance on ordering this rear diff because of the awesome price and reviews (we were skeptical.) He had to get a few small parts from the auto store to go with this (bearings, I think and gear oil) but he got everything installed in a day or two and it works GREAT! The truck now drives better than before, no strange noises and it is holding up great through daily use and abuse. Highly recommend this part (you’ll find this exact part for a few hundred more on other websites!)

quality and easy install

Ordered this and the bearing kit. DON'T order the 'bundle'- it jacks the price of the combo almost $120 over buying separately.My G80 took a dump. Took down to my brother in laws shop and we installed there. 2Hi feels so much more sure footed and smooth. Of course we haven't gotten any snow since, but driving through some greasy mud seemed to be no factor compared to prior.Yukon could at least include some stickers! I was joking about them not being included, and fortunately my brother in law had some from installing Yukon posi's in customers cars. Got one for my toolbox that way, but it's a 'performance' brand and product and should always include at least a couple stickers.

Everything is perfect. Can’t wait to get it installed

Muy satisfecho, calidad, precio y todo en tiempo

Installed in a 2005 TJ Sport with a Dana 44, 30 spline axles and 3:73 gears. Had a spartan locker in the rear but removed it because it was too aggressive on pavement (but great on trails). Installed this limited slip and the jeep still performs excellent off road but drives far more comfortably on road. Highly recommend. Does not come with bearings so that’s an added cost. Use 80-90 limited slip gear oil and an additive for best results.

Very impressed with this posidrive, takes all the torque and some just make sure to use a bottle of Yukon anti slip and good to go

trabaja muy bien recuerda usar aceite no sintético.
