distributorguy Posted January 23, 2017 Report Share Posted January 23, 2017 Is this the only H190 LSD kit available? http://www.ebay.com/itm/like/252266397483?vectorid=229466&lgeo=1&item=252266397483&rmvSB=true I have a call in to Nismo about the Detroit Locker availability and price. A mini-spool would be perfect for what I need. If someone like Yukon Gear made them, would anyone else want them so they can stop welding up diffs? Quote Link to comment
]2eDeYe Posted January 23, 2017 Report Share Posted January 23, 2017 I'd like to see how that thing works... no supporting or technical information on that link. Your unlikely to find a mfg that will support the H190, it has been tried. I do wish you luck in your endeavor though :) Quote Link to comment
distributorguy Posted January 23, 2017 Author Report Share Posted January 23, 2017 For the price of tooling up, I could buy a 9", but someone may have a product that can be modified to fit. They do a nice job of hiding the mechanism in a CNC housing. Spring loaded with clutches. I'd like to see a simple heat treated axle coupler for a full locker. I wish I had a spare diff around to play with. Quote Link to comment
Lockleaf Posted January 23, 2017 Report Share Posted January 23, 2017 Also known as phantom grip. They do technically work, they just create excessive wear. Someone started messing with an H233 clutch lsd carrier trying to fit it to an h190. They could machine it down far enough to fit, but the 190 is 29 spline and the 233 is 31 or 33 spline depending on year and application. They never overcame that hurdle. Quote Link to comment

datzenmike Posted January 24, 2017 Report Share Posted January 24, 2017 That's the Phantom Grip.... http://community.ratsun.net/topic/70820-r160-lsd-ebay-conversion-kit/ http://community.ratsun.net/topic/6744-phantom-grip-2-way-lsd/ http://community.ratsun.net/topic/28066-r200-front-lsd-differential-on-pathfinder-king-cab/ http://community.ratsun.net/topic/41391-79-210-coupe-rear-diff-options/ Quote Link to comment
distributorguy Posted January 24, 2017 Author Report Share Posted January 24, 2017 Thanks. I wasn't searching for "phantom grip." Lots of failure stories, no proof that I could find, until now. The theory makes sense though. Since I have custom made wheels for the 6 lug axles, I need a solution that uses those, and at the stock width or a little narrower. We'll see what Nismo says about a DL unit in stock. I think we have the 4.375 gears for now. We may want a 4.11 set too if I can find one. Anyone have spares lying around to sell? I know - use the classifieds for that... Quote Link to comment
datzenmike Posted January 24, 2017 Report Share Posted January 24, 2017 The '89-'93 D21 Hardbody had an H-190 LSD option. The H-190 was only available on the 2wd 4 cylinder truck and should have a stamp sized orange LSD sticker on the 'bum' of the differential. Good luck in the wrecking yard lottery finding one. They came it 3.90 and lower ratios so you would have to swap the C&P into them. Quote Link to comment
distributorguy Posted January 24, 2017 Author Report Share Posted January 24, 2017 ...and you'd have to hope the clutch pack wasn't worn out. Might be money better spent to get a new one if I can find it. Or swap to a 9". Quote Link to comment
datzenmike Posted January 24, 2017 Report Share Posted January 24, 2017 Probable the clutch parts are still available. Just an option. Wayno found one once. Quote Link to comment
distributorguy Posted January 24, 2017 Author Report Share Posted January 24, 2017 There's a whole Hardbody here on CL right now. Cheap. I have a question out regarding the diff in it. Decent miles, but... No one junks anything here in MN so the scrapyards are full of scrap. A LSD would be $350+ here. and worn out junk from a salvage yard. Quote Link to comment
Stoffregen Motorsports Posted January 24, 2017 Report Share Posted January 24, 2017 Welding is the cheapest option, but be sure to check the carrier for runout after welding, and true it up if needed. A 9" is probably your best option though. The availability of aftermarket parts is incredible. I've had complete rear axles (with diff) built for about $1700. Those are from Currie. There are tricks to revitalizing a worn out OEM LSD unit. Free tricks requiring only labor. Quote Link to comment
wayno Posted January 24, 2017 Report Share Posted January 24, 2017 Yes I found a H190 LSD in a hardbody a few years ago, it has 350 gears, I didn't actually believe it was an H190 until I installed it in a 620 rear end housing across the row from the hardbody, I got all happy when the 620 axle dropped right in. The reason I asked what gearing you were looking for is because I have a 411 geared H190 Detroit Locker I am not using, if your interested PM me. 1 Quote Link to comment

distributorguy Posted February 1, 2017 Author Report Share Posted February 1, 2017 Locker in hand, I'm still hunting for a 4.11. Just the gear set (or pumpkin), which I presume all the 620 and 720 versions will bolt into an H190 3rd member, correct? Or did they change the bolt sizes at some point? Quote Link to comment
]2eDeYe Posted February 2, 2017 Report Share Posted February 2, 2017 They will bolt in up through the hardbody as long as it is a truck H190. The earlier 520/521 diff is aluminum, if you are looking for some weight savings. Quote Link to comment
distributorguy Posted February 2, 2017 Author Report Share Posted February 2, 2017 I'd like a casting even heavier than the cast iron version. Land speed racing. Weight is good. Quote Link to comment
]2eDeYe Posted February 2, 2017 Report Share Posted February 2, 2017 Then I would suggest getting the newest version that you can find as the received more structural reinforcement as time went on. :) Quote Link to comment
G-Duax Posted February 2, 2017 Report Share Posted February 2, 2017 The earlier 520/521 diff is aluminum As were the earlier 620s. My '73 had an aluminum carrier. I would have kept it, but the newer H190 LSD was a tad to wide, so I had to go to the iron carrier, or do a shit load of machine work. 1 Quote Link to comment
