Description

The YDGF8.8-31-1 Yukon Dura Grip is the ultimate choice for those seeking smooth yet aggressive traction in a limited slip differential. Engineered for long life and completely rebuildable, this differential is designed to provide the confidence and performance you need across a wide variety of terrains. Constructed with a high strength nodular case, forged 4320 chromoly spider gears, and composite clutches, the Dura Grip offers unmatched positraction performance for vehicles demanding durability and strength. When it comes to purchasing automotive parts, it's important to understand the differences between authentic products like the Yukon Dura Grip and knockoff counterparts. Knockoff differentials may seem like a bargain, but they often lack the quality, durability, and performance standards of genuine products. Investing in an authentic Yukon Dura Grip ensures superior quality materials, precision engineering, and state-of-the-art technologies that undergo rigorous testing to meet stringent quality standards. The performance and reliability of a differential are crucial factors to consider when making a purchase. The Yukon Dura Grip is designed to deliver optimal traction, enhance handling, and maximize torque distribution for improved vehicle control and stability in demanding conditions. Knockoff differentials may fail to deliver the same level of performance, potentially leading to reduced traction, excessive wear and tear, and even complete failure of the differential system. Choosing an authentic Yukon Dura Grip also comes with the added benefit of warranty and support from the manufacturer. Genuine products are backed by a warranty that protects buyers from manufacturing defects and ensures prompt resolution of any issues. Knockoff differentials often lack this support, leaving buyers vulnerable to costly repairs or replacements. Safety is always a top priority when it comes to vehicle components. Authentic Yukon Dura Grip differentials are built to meet stringent safety regulations and undergo thorough testing to ensure optimal performance under various driving conditions. Choosing an authentic product ensures the safety of both the driver and passengers, providing peace of mind and longevity for your vehicle's differential system. In conclusion, investing in an authentic Yukon Dura Grip differential offers superior quality, durability, performance, warranty, and safety benefits that far outweigh the initial cost savings of knockoff alternatives. Don't compromise your safety and driving experience - choose authenticity over imitation. The Yukon Dura Grip is proudly assembled and quality tested in the USA, ensuring top-notch quality and reliability for unmatched positraction performance.

  • Good Quality part for the money.
Style: Chrysler 9.25" with 31 Spline 2010 &... Pattern Name: Differential
Replaced the open differential unit in my 99 Dodge Durango with this limited slip unit and it is an awesome upgrade! On the 9.25 Dodge differential replacement is simple I suggest using only "Timkin" bearings, good quality gear oil and limited slip additive. I used Lucas 85W 140 gear oil and their additive. The differential is working perfectly. While you have things apart it is a good time to inspect/replace the outer axle bearings and axle seals which are very easy to replace at that time as well. ... show more

  • AMAZING PRODUCT AND CUSTOMER SERVICE FROM THE COMPANY!
Style: GM 8.5"/8.6"with 30 Spline Pattern Name: Differential
This is the second rear end we have had to replace in my 05 sierra with 400k miles, so far we have had no problems with it.. the company's customer service team was absolutely outstanding when i had trouble with my purchase of their $40 lifetime guarantee for this part. My card was saying I had been charged twice, but the gentleman made sure I wasn't and even shipped the card for the warranty next day for 100% free! then called me again to tell me he had the tech people check just to be sure. I cannot say enough good things about this company and the people working there! definitely would buy again if i didn't have the warranty for it! ... show more

  • Great upgrade or replacement. Going strong!!
Style: GM 8.5"/8.6"with 30 Spline Pattern Name: Differential
Installed in a 2001 Tahoe. Over 10K miles on it now and no issues. It's very nice living on a farm and not only having 4wd but now having a limited slip rear end. Haven't really needed the 4wd since installation.

  • Life saver!
Style: GM 8.5"/8.6"with 30 Spline Pattern Name: Differential
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!) ... show more

The part itself was fine, direct replacement for gov lock, easy install and no problems with performance. AMAZON....IF YOU ARE GOING TO OFFER ONE DAY SHIPPING THEN DON'T SHOW UP AT 9PM THE NEXT DAY AND CALL IT "NEXT DAY SHIPPING". YOU ARE PROVIDING FALSE HOPE.

  • so far so good, still good update!
Style: Chrysler 9.25" with 31 Spline 2010 &... Pattern Name: Differential
Updated at bottom.. I didn't just randomly decide to upgrade...this was more a question of what to replace existing yet failing parts with. My 2000 dodge 1500 4x4 was making noises I didn't like... we popped the rear pumpkin and discovered the issue after noticing HUGE driveline rotational play. My differential spiders were definitely on the way out fast...and apparently decided to wallow out the carrier at the same time. Ok I need to get the best value for money spent....would prefer easy to install and while I can accept a higher noise level I would rather not most times. Yet if I could up the off road performance a bit that would be nice. So their went the lockers... more expensive more noise.... The cost difference between a replacement carrier and spider assembly and a LSD wasn't that much. The cost of a lunchbox locker and carrier made that and the mini spool and carrier fall off the table as well as sound and on road issues. So I chose this... as my ring and pinion were just fine.... we set the lash at 0.0055" play and lubed up the rear end with 80-90 conventional as required by yukon and the LSD additive. Over an open differential it's a big step up. Over a failing open differential it's a huge step up. Now my DD/hunting/fishing rig is more capable and for roughly $60 more than replacing the entire dif with an open one I got added traction. Thanks yukon. Approx 1 week later Still happy with it.... it makes a big difference in offroad and on road handling. Yes it opens when not under load but if hard cornering with heavy throttle on a slippery surface (hard packed dirt road....sandy tarmac) expect both rear wheels to break loose and a drift or powerslide to start. Not a bad thing and definitely improves throttle steering but it does change the handling and you should be aware of it. I do realize I drive harder and more confidently than many people especially offroad... and that most folks are just happy to get there they don't need to have fun while getting there quickly....but I do. ... show more
