Wondering if anyone has given one of these a try? Good or bad for street/strip?

"Spartan Locker - AMC Model 20 - 29 Spline

$279.81

Quick Overview
The Spartan Locker by USA Standard Gear is a mechanical locker that replaces the spiders in a standard case. The Spartan Locker's design does not use the thrust washers and has a revolutionary spring and pin design that makes installation a snap! The couplers and drivers are made from 9310 steel, for added strength. Each Spartan Locker carries a one year warranty."

Thanks.

I haven't used the Spartan, but I have installed Detroit EZ-Lockers and Lock-Rights. Google "Lunchbox Locker", they are used a lot in Jeeps. They all work on the same principal. They work relatively well and are pretty strong. You will get a ratcheting sound in corners and an occasional bang as they engage after a corner. They will cause a pull if tires are unequally inflated or worn, and will understeer if you power thru corners.

So probably not the best choice for a car that I'd like to be able to drive to work during summers.

Sure.  No problem driving it daily!  Just use caution and common sense.  I daily drive my lincoln locked ford ranger and have no problems.  It wont handle like a slalom car, but to be honest, does it now?

Not a problem once you learn the quirks and learn to compensate for them. I drove my Detroit Lockered Jeep CJ on the street as a daily driver for years.

But would you have put one in your AMX if it had a single spin? If I got one it'd be for a '68 390 4-speed Javelin. Sounds like they get used more in Jeeps.

Dont fear the gov lockers, I have a Detroit TruLoc and love it.   On a turn, you can decide if you want engagement really....because  it acts open unless a bit of load  is sensed. Then it gives alittle bit of chirp at times.  The tork is sensed when you give car throttle.  Drive normally and turns are like an open dif.  I like sounding scrappy and powering out on a turn and getting the chirps. With clutch posi, theres always fighting on a turn. Pulls from a drag are great with exact tire marks tire to tire...Its great.

Lockers are least streetable when used on short wheelbase vehicles (CJ5).  If you have a longer wheelbase vehicle (Javelin) you'll be fine.  They do make a little noise and have their own quirks- just like any type of limited slip diff.

How much work is involved on installing one of these lockers for a backyard mechanic with a $99 Craftsman tool set? Can it be done with the axle still in the car? Would it be wise to get the axle lug nuts torqued to 250 foot pound prior to installation?

So I already have a later model twin grip ready to install (1 piece Trac-lok, much weaker than the earlier 2 piece Powr-lok), but I don't want to install and have it crap out the first time I dump the clutch with slicks. I'm not sure, maybe it'll be fine. Have to say I'm intrigued by the lockers. Probably more durable but not sure if worth the roughly $300 more to get one. I've also got the Moser solid axles ready to install. Just don't want the diff. to be the weak spot, but as always money is a factor.

Any recommendations one way or another?
