thats funny! lockers can come in handy in strange simple situations too.a truck like yours SHOULD go places where a stock ZR2 cannot go, unless a front locker is needed, and I have needed mine twice, uphill in mud. You know, when you have parked at the bottom of a hill to go hunting, sun comes out and thaw's out the road....
The difference in my use for instance. where I hunt I have about 6 miles of rutted, wash boarded dirt/sand roads to travel plus cattle pastures. I can cruise right over it with not much trouble. My brothers F-150 haas to ge real slow or it will walk all over the road and rattle and bounce his truck to death. Last year after the 3rd day,he said I will pay for the gas if we take your truck from now on...during this time is when I IMOP am using the ZR2 for what it is made for, not rock crawling. Sometimes I wished I had one of each, a ZR2 and raised twin
Kind of funny thing I saw a couple weeks ago that has to do with the lack of front lockers....
I was at the public park after a week of rain and a guy could not find a place to park his new full size chevy 4x4 silverado. about $42k I guess.
so he drove forward straight in over the curb and parked on the grass. even with signs that said not too park there. he had his tailgate parallel to the curb about 6 inches from the curb.
we walked our dog and sat and 3 hours later came by and saw him slowly spinning some wheels in the flat grass now slick with mud. not moving at all and had not dug holes either. I looked and some front and rear tires were spinning. he also tried wiggling the front tires back and forth unsuccessfully. this was on completely flat ground. just slick mud under grass.
he was not moving. then I realized he also had a large tow truck off to the side on the pavement that started pulling him slowly back with a strap at an angle since space was tight. he pulled him 2 feet to the curb and over it!
really funny to watch that big 4x4 not able to back up 2 feet.
I guess he needed LOCKERS. or maybe 4 or 5 guys could have pushed it by hand.
I think 4x4 Silverado's only have a rear locker if you option it. his was probably just a 4x4. and no front locker options available at all?
so a locker may have helped him. or maybe all 4 would spin?
but I have used mine in my driveway about 6 times successfully to get me out of spin situations. I have tight space to turn around on a off cambered multiple banking slope that puts you into my fence since you can not turn tight enough to clear the fence. so you end up having to back up the hill to get away from the fence and complete your turn. kind of a K turn out of my parking spot but you have to backup 3 times, sometimes 4 when the ford focus is in the way . all the time being on a slope and various banks around big redwoods.
one rear wheel will get compressed high up in the wheel well and one will be in the air or really light weight on it. so it just spins. as you complete the modifid K turn to get turned around and down the steep windy banked driveway.
doing 4x4 mode usually helps but that too can spin in front on opposite wheel and you slide forward more. so sometimes I have to straighted the steering and use both LOCKERS and it slowly backs right up.
my wife likes that!
with my old 57 CHEVY 3100 rear wheel drive pickup it use to get stuck there and she had to get out and jump on the rear bumper or get in the bed to help get me backed up a bit! sometimes we had to call my son down to help push a bit.
So we like the 4x4 and lockers on the zr2!
we also have had UPS trucks slip and hit the fence 3 times. I hit it 2 times with my camaro, my wife knocked boards loose about 5 times in Focus. my son hit it a couple times with his 300zx and his parhfinder.
and once a fedx truck got stuck against the fence and had to get a tow truck to lift him up and back to fet it out. funny! they park at the bottom of the driveway now!
that driveway is a killer to navigate!
I do love the 4x4 and lockers just for those situations. grear so far. im waiting for the winter mud slides to test it more.
So you bever know when you might find use of the lockers. nice backup system before having to get a tow or pull.
