The Posi-Lok systems give you direct control of your front axle right from your cab, so they will engage every time. They have a short 1 in. throw to make shifting on the fly easy, and as an added bonus, a 2WD low-range to give you the rear-wheel torque of 4-LO, and the bind-free steering action of 2-HI.

Q:

Will this fit my 89 Power Ram? Wondering why it says it fits a Dodge Pickup but the other customer with the 87 W150 was told it wouldn't fit.

Asked by OLIVIA on November 14, 2017

A:

It may have to do with the size of the front axle. I think the w150 runs a Dana 44 and the this for a Dana 60.

4x4 posi-lok - great product

Summit RacingSummit Racing Verified Purchase

POS-400
Purchased this product for my 1998 dodge ram 1500 (dana 44 front axle) after the factory vacuum system failed to work. The 4x4 posi lok includes everything you need to convert from the factory vacuum or electric motor to direct manual cable to engage your front axle. Once you remove the center axle disconnect on the front axle the posi lok bolts right on in its place. I found the installation to be very simple, with great instructions included. All you really need is a few specific drill bit sizes and basic tools. After about an hour it was installed and ready to go. The red button included mounts by your right foot above the gas pedal. I was originally concerned that the button would be in the way but I was relieved to find even with big boots on it does not get in the way of the gas pedal or my foot at all. There are knock off products that look just like this, Just be careful as to what you buy, I would recommend buying from summit racing, not anywhere else where you might not be getting the real thing. I ordered through summit with priority air, and i was very happy to find that it arrived the next morning. I take my truck on trails regularly and I have found the 4x4 posi-lok to be extremely reliable. It does require one extra step though. Instead of just taking the factory 4x4 lever in your truck and putting it into the 4H position you also have to press the button and pull out to lock the front axle in. I have found that the best was to go about switching from 2h and 4H in an off road situation is to keep the front axle engaged with the posi lok and use the 4x4 shifter in your truck to decide when the front axle is getting power or not. The system also allows you to use 2low, which is cool. Overall, the 4x4 posi lok is awesome and in my opinion the best thing you can do to a truck(or jeep or whatever your buying for) to ensure your 4x4 will always work when you need it! I can't say enough about this product I have already told all my friends to buy them. If your considering this product just go for it, it's well worth it! ...read more

I received the Posi-lok 400 for my 2000 dodge diesel 4x4. The kit looks pretty good. I'm not real sure about the finish on the mating surface of the housing adapter. It appears a little rough to say the least. The mount surface looks like someone ran a flat file to knock down the high cast spots in the center. The rest is just a porous cast finish. I will lap the housing or machine flat before installing. Don't like fixing leaks later. Been A CAT mechanic for 15 years. This will not seal well as is. maybe this is an isolated incident? Better Quality control? ...read more

I had previously watched a you tube video on exactly how to do this installation on a Dodge Ram 3500 4x4. Job went very smoothly and worked very well. For the first time since we've had the truck we now have 4 wheel drive and even better 2 wheel low. Great product.

Everything needed was in the kit and install was easy. Make sure you have some gear oil handy on mine i lost about half a quart. Works really good and alot cheaper than swapping to a solid axle
