I have the same dilemma, but with my 2x4. My truck is darn near useless in anything slicker than dry pavement with the peg leg 60. I almost got stuck with my car trailer going around an uphill right hand turn on wet asphalt! Embarrasing... The Powerlock is the best clutch LSD for the 60, but at $550 it is as pricey as the Detroit Locker. Here are some solutions and my reasons yay/nay:

Detroit E-Locker-best of both worlds. Worm gear torque biasing LSD with no parts to wear. Flip a switch and fully locked. Cost about $1000. (edit: found for $800 several places.)

ARB- open or locked, also about $1000 with compressor, but not
as useful as e-locker imo.

Ox Locker. This is a cool mechanical cable actuated locker. Open or locked. About $900 and also not as useful as the e-locker.

Detroit Locker or soft locker- $550 or so. Super durable. Noisy, not good for pulling a trailer as they say you get some butt shake. This is a deal breaker for me. Also introduces a lot of drivetrain lash that is not present with other type diffs.

Powerlock-best clutch type LSD for 60, but also expensive at $550 as noted above.

Lock Rite-Less than $300 and can be installed without removing the carrier and ring gear. This is a real plus because 60 preload is set with shims between bearing and case, so everytime you adjust preload or backspacing, the bearings have to come off. PITA.

Traklok- The deal in 60 LSD. About $290 at Drivetrain Warehouse. This is the solution I made. I don't need 100% traction to one wheel pulling a boat. I just need something to reliably send power to both wheels. I find it hard to believe that on wet pavement or mud that their is much lost efficiency in the Trak Lok.

FWIW, I have a used Trak Lok for sale. I'll take $125 plus shipping. I bought it from a guy on the board for the 60 in my Jimmy, but I have decided that when I go to 8 lug wheels I'll just suck it up and buy the e-locker since it is what I really want. It is a 30 spline unit for 3.54-4.10 gears. Possibly 4.30, not sure where the break on the 4.30's is as they don't show them usually. Same with the rare 3.3's, but obviosly they go with the lower case.

Where is Rocky Mount? I am in St. Louis doing 9 weeks of training for a new job. Be here for 5 more weeks if you are anywhere close wouldn't mind having a cold one and checking out your truck.
