Lookin for locker advice

My big toy is a fullsize 88 GMC Jimmy... 350 motor with no mods other than exhaust, 4" suspension lift, 36" TSLs riding on 10 bolt axles with 3.73 gears. I do plenty of muddin... no crawlin or anything like that. I discovered during the winter tryin to pull some friends out of the snow the limitations of the open diffs.

Now I know that what I really need to do is to swap out the lil 10 bolts for some 1 ton axles but around here those axles cost a bunch of $$$, not to mention I would have to buy new wheels since my MT classic locks are 6 lug. I definitely want to do that but the cost is prohibitive right now.

I looked into Detroit Lockers but for the $$$ it seems like throwing good money after bad to install them in 10 bolt axles that I will probly get rid of. So I'm thinkin that just to get me by I would go with a Lock Right just in the rear. Most of what I go thru I can get thru in 2WD anyway and I'm pretty sure if I had the rears locked it would do most if not all of what I want it to do. I've also heard that installing lockers in the front can result in some crazy steering suprises on the street which I'd like to avoid.

I'm looking for feedback on the Lock Rights. Are they worth the $328? Do they stand up pretty well to moderate off-roading? Am I right in thinking I can get away with just locking the rear axle? Are there any installation tips that I oughta know?

I've heard good things about the Lock Right. If yours has an open carrier already, I believe it fits right and you won't have to re-set up the ring and pinion.
I have a Tru-Trac in the back of my Suburban, and the difference between that and the gov-lock it had before is night and day. I can definitely go more places now than I could before, and I think you will see similar improvements by just adding a traction aid in the back.

i welded a 10bolt and its held up for a few years but im easy on the go foot and only have 35s boggers on.

what i did was weld the spiders together. i pulled the ringand pinion to do this. i also pulled it later just to see if any welds cracked and theyre all holding just fine.

i run 350 with very mild cam and 3" exhaust with tbi heads its pretty gutless.

on road it definatly drives difrent i have no swaybars and 52" rear springs and a shackle reverserl. at speed 50mph the rear will grab the road and walk away from the rig. pretty scary.

the difrence offroad is amazeing, i rarely lockt the t-case im just useing the blazer for hunting.

back when i was into wheeling and modding i bought a dana some axles for the blazer but theyre just sitn behind the house right now. i plan to someday put them in and will most likly weld the rear and leave the front open justthe same as the 10 bolt

guess what im saying is im a fan of the lunchbox locker.
