So here is why you can't plunk down 1800 for anew posi and street strip drive a 500 HP car with 8.75 rear axle and a 4speed. This factory Yukon gear 8.75 had 150 street miles 25 street hits and one drag strip burn out and this happens at the line. PSA don't buy clutch type Yukon gear for any thing that is more then stock . And even then I would not buy it . This is not to slam any one I just want to warn our Mopar community this stuff is not safe for spirited muscle cars at all! Save your... Read more

Considering options for replacing my 741 open rear, 66 Coronet Randy's Ring & Pinion Fully rebuilt rear with Yukon housing and Sure Grip diff is 3.73 & 3.90 gear $1,747.89, 3.55 gear $1,864.89 Rather than buy an HD 742 or 489 case then buy rebuild kit, ring & pinion, and differential from Randy's and then pay for rebuild or buy $300 in tools, it's cheaper to buy a fully built Yukon unit. https://www.randysworldwide.com/products/ydac889-390pl However, Doctor Diff parts are considerably...

Well, it’s finally time to start a thread documenting the resurrection of this 1977 FJ55 that I bought sight unseen a couple of years ago. I found this truck on Kijiji for $2000 (Canadian $$, that is), the only glitch being that it was located in Whitehorse, Yukon, which is *very* far from my hometown in southwestern Alberta. Luckily I was able to arrange an affordable ride on a fellow’s step deck trailer, and so after a few weeks it was plopped on my driveway. I immediately started using it... Read more

I stole this idea from the "Yukon Jack" thread posted by @diesellibrarian . I saw the pic and said "Aha! That's so crazy that it just might work!" diesellibrarian said: View attachment 4231022 Click to expand... Seems that the PO had the same problem I was having. Problem is the metal tab that the thumb-button pushes against is thin and flimsy and bends away so that the thumb-button no longer works. You can see that Toyota added a threaded bit to end of the thumb-button rod on the later handles to address the problem. In... Read more

Alright everyone I'm getting sick of breaking Dana 44 parts. I've got a spidertrax housing already and a 609 has always been the plan for next big upgrade. That being said I really don't want to bite the bullet on the 5-6k...or more that its going to take to get the spidertrax under it right now. Is it worth doing the D44 RCV and yukon hardcore lockouts right now for a little over 2k and try limping it along for another year or do I just start putting aside the 609 fund and do that sooner...
