PSL500 Black Aluminum Fork Terminal

Worked perfectly on my 2003 S-10. instructions a little lacking but over all exactly what I wanted. picture was before it was installed and only had 2wd.Gives you the option for 2low and this thing works perfectly no more hoping everything works just pull the lever and let it eat!

My old 84 Blazer had the old vacuum system to lock front differential when in four wheel drive. After doing some online research on how to repair or replace the vacuum system I decided to try the Posi-Lok system. It was easy to install and it works as advertised on their website. I have used the 4X4 on several occassions and it locks and unlocks front differential with ease. After deciding on Posi-Lok I searched and found best price on Amazon and devlivery was very quick.

install instructions are not the most complete. Fairly easy installation. Solves the prone to failure vacuum actuator on a lot of 4x4's

Picture is of the 1st kit, what I got was the updated 2nd kit. Cable goes straight to the front axle fork to engage 4x4. I was so glad. Anyone can install and works everytime. Now I have an extra option of (2wd low!) if I dont pull the cable, great for getting my boat out of the back yard! I can steer Normal, no binding. You still use your transfer case buttons, and no guessing if the 4x4 is working. Best thing for my 2003 blazer.

The 4x4 posi lok system Solved the front diff not engaging fully problem in my 2001 Chevy s10 ZR2 blazer. Whether you have a vacuum problem or an actuator problem, as long as your transfer case switch works to make your front driveshaft turn, you won’t have to worry about your front differential not engaging anymore. Just simply press your 4x4 hi or low button like normal, then pull the 4x4 posi lok cable, then twist it to its fullest outward adjustment and you should be good to go. Can’t give it 5 stars because of the horrible instructions (or lack there of a few steps). I’m decently mechanically inclined and it took me 4 hours between figuring out where to drill the hole and the best place to route the cable to my front diff up and and around the front of the vehicle, and then troubleshooting why it wasn’t engaging when the cable was pulled. It was a headache since I figured it would only take an hour or 2 at first but overall I’m happy with this product. (If pulling the cable doesn’t engage your front diff, turn the handle counter clockwise to adjust it outwards once the cable is engaged fully outward. And once you disengage it turn the handle clockwise so it doesn’t stay stuck out as far. It took a while for me to figure this out and ended up finding it on a ram forum. There weren't very many people with s10s troubleshooting these online that I could find. Like I said the lack of installation steps and operating instructions kept this from a 5 star review.

This is a great product at a great price.

Works great. Little difficult to find spot in cab to mount control. People just need to remember, after you disengage the front axle, you need to back up 5-10 ft so it actually disengages. Same as factory

Product works. Directions suck. I routed it a whole different way than the directions tried to explain. The cable is overly long too, so you have to get creative with dealing with the slack. Oh also, it will work on a 2004. They say it goes up only to '03, but the '04's are the same thing.
