I'm going to be a 4.10 gear change over this winter and I was wonder what lockers I should go with. I have an 03 F150 with the 5.4 motor, 35" tires and it's going to be my daily driver. I'll use it once in a while for offroading so I want something that will do good when I loose traction but something that will do good on the street too. I've read a little about the truetrac being strong and pretty good for on and off roads but I saw something about voiding the warranty with tires over 33" or something like that. I've read about the elocker and you can select what you want but aren't bulletproof like the truetracs. I've also read about the stock LS diff being kinda crappy so that was one of the reasons for going to something better and since I'm doing the gear it's the perfect time to do it and not have to worry later.

The Trutracs are awesome. This should honestly be your only choice if you arent in to hardcore wheeling. If you think you "have to have" a locker then make sure you get s selectable like an ARB or the one you mentioned. A full time locker like a lunch box locker or a full detroit will engage and disengage on its own when there is wheel slippage. This means almost every turn, every time you reverse, etc. I have owned all types and IMO the only differential for a street truck is the trutrac.

+1 for true trac. Love it in my truck.

I think it depends on what you really want to do and how much money you want to spend. I put a Tru Trac in my Rear end and a E-Locker in my front. Tru Trac was way easier to install and its a solid system with no maintenance involved in it. The ARB Locker i think is better than the E locker however then you have to have a pressurized system as well to run it... If i was doing it again i would have put Tru Tracs all Around.

Working in an off road fab shop arb air locker or electric aka e locker would be the best for a daily driver my truck has a Detroit lock but there is no Turning it off or on so on the street it can be hard on tires and the dif as it drags a tire around turns

But we always recommend arb and haven't had problems with them really and with an electric locker u can turn it on or off for when ur on the street or the dirt

I have tru tracs in my cherokee and love 'em, but it really depends on how deep your wallet is. Air lockers are the best option, but at nearly $1000 for each one that's just waaaaay out of my budget. But the other benefit is that you will have a compressor on board and you can fill up tires with it too.

Why are you going to regear to only 410's? The reason why I am asking is that 410 are better for 31" tall tires, 4.56 are for 33's and 4.88's are for 35's. Do some research on this before you buy? You will be very disappointed if you go with 4.10's.

I've read that air lockers or electronic aren't as strong as the tru tracs since they still have clutches in them and I don't want to put out 1000 bucks each. All season I have 3.55s and I can still pull a pretty good sized trailer but the off the line power is lacking. The one site I was looking at said 4.10s are good from 33 to 37" tires. I have a set of 33s that I'll run as a winter tire and the trail grappler for the summer. With a 4.88 that will be too much for the 33s.
