Holy cow! Those pics of that diff are impressive. Was not expecting it to be that beefy. Big old spring and 4 pinions. Definitely changes my opinion on them. Still getting the itch for a true locker though. Those Harrops have my attention. LandCruiserSpecialists here in Austin are going to be a vendor and already have 5 scheduled for install on 100s. Should get really good feedback from them.
Yeah, the LSD is a stout unit (in its construction), but it remains....spring pressure and friction discs will lose their effectiveness over time. But more importantly, I want to have the option to 'select' when I have a traction aiding device operate.
Keep me updated on what you hear from LCS. I grew up in Austin, went to school there and most of my family still lives there. I am equipped to set up my own diff, but it would be so much more convenient to drop off the LX at LCS and have them do it...while in Austin visiting.
