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.

Let me know if you have any other questions. Thanks, BRYDON 641-751-8060 staticz2229@gmail.com **Q: Is this a drop in replacement?** A: Almost a drop in unit, you will have to move your ring gear from your original unit..and press on new bearings... **Q: Will this fit a 1973 Pontiac Firebird?** A: First answer is not correct. This is NOT for a 9.5” 14 bolt. The description states it is for a 10 bolt 8.5” or 8.6” with 30 spline axle shafts ## Customer Reviews ### ⭐⭐⭐⭐⭐ so far so good, still good update! *by L***S on January 18, 2023* Updated at bottom..
