It's time increase traction in the rear of the old Jeep.
It has been said one should "Never lock a D-35!", that's fine because I don't think I want a locked rear end.
The little Jeep is currently running 4.88's with a Spartan Helical LSD in the front and am extremely happy with it, I was thinking about installing an Eaton TrueTrac or PowerTrax Grip Pro in the rear.
This should increase traction and replace the weak spider gear assembly, distributing power more effectively to the wimpy 27-spline axles ...
My theory is that the helical lsd should be easier on the axles than a locker, and reduce the chance of snapping an axle. ...seems logical????
To be clear, I don't rock crawl and don't spend much time with one wheel in the air, I don't think I need a locker. It would be great it if there were a Super 35 kit with a truetrac (I would buy it right now) ...but there ain't. so that leaves:
Open diff →(as a last resort)
Rear end swap →(Maybe later, not right now)
Lockers; 27 spline or super 35 →(no)
Clutch style lsd's; 27 spline or super 35→ (no)
Selectable lockers; 27 spline or super 35 →(no)
Helical / Torsen style LSD; 27 spline only →(this is what I'm leaning towards)
The D-35's strength isn't a huge concern (famous last words) and I don't want to invest in a rear end swap at this time, as I currently have other projects to tend to.
Mostly I'll be driving up skidder trails, muddy / snowy logging roads and things like that. Light to moderate off roading.
Right now the only other viable option is leave it as-is and use the winch more often.
Is anyone running a helical lsd in the rear or have first hand knowledge of the performance that can be expected?
Reasons to NOT install one?
Let me know what you think.
