Most Popular 30 Inch Lift for GMC Sierra 3500

Finally got around to installing my PT II Stabilizers 30" front and rear of our 26' Surveyor. Pre - assembled them to make sure they went together ok. Luckily I had two sources for power front & rear which made wiring easy, I used a Buss block to make all positive connections, grounds straight to frame, soldered all connections and heat srinked to seal. Using the 3/8" self tappers was fun.Well got it all together and all works well makes trailer very stable, don't have to worry about scissor jacks collapsing anymore.

I finished the assembly and install of the power twin II stabilizer and have included pictures of the install. This is a good quality unit and I am very happy with how it works. Bob

Deception in advertisin It may be my fault for not reading to total description in detail rather than glancing over it. Similar products from other companies list the weight capacity as each but this product lists the 10,000 pound weight capacity as both. They are only good for 5000 each. The [online] option was at least 6000 pounds! The only reason they were not returned is the 30in capability.

These worked out great easy to install with the circular mounting plate.

Box is damaged and tape all over with clear tape holding box closed and first thought is missing parts and paper work and instructions to install ! Pictures taken and open up box finding all parts inside except for the paper work instructions to install, also the rubber cover for the water poof motor is damaged also!

Good thing stabilizer was easy to install because there were no directions included. Item was delivered quickly. I received item within a week.

Pros: Works better than I anticipated. Looks great and has better ground clearance than the stock scissor-jack stabilizers. Cons: Installation instructions/documentation weak or non-existent. If all of the instructions, wiring diagrams and documentation were in one place on the web page under a separate tab rather than having to dig through the reviews and the Q & A’s, I would have given this a 5 star rating. I ordered the LCI Power Stabilizer Jacks with the white switch Kit (LC369774) because I wanted the switches mounted in the camper wall so they would be better protected than if they were mounted in the flimsy fender skirts of my camper. I also needed the bolt-on spacer kit (LC673594) for both the front and rear jacks to clear a propane line that runs along the length of the frame. Installation was relatively easy, although there are NO instructions on how to install the spacers kits; the video on etrailer.com was no help whatsoever with the installation. I bolted the jack mount brackets to the shorter side of the spacers using carriage bolts and flange nuts; the slotted holes in the spacers accepted the carriage bolts, aligned perfectly with the holes in the jack mounts, and allowed me to install them without having to try to fit a wrench inside. Then it was just a matter of drilling holes in the frame at the appropriate spacing for flange bolts/nuts through the slotted holes on the end of spacers. I was very pleased with how the switches and the switch compartments looked once installed. Again, though, it took lots of digging to find the wiring diagram and then the matrix for the switch wire colors, because the wires on the white switch are colored differently than the black switch that all of the diagrams show. Also, it states on the jack installation instruction sheet that the power must be a minimum of 10 gauge wire (AWG-10), but nowhere on the wiring diagram does it say anything about that. AWG-10 is a MUST because of the way current drops over a distance. In the case of my camper, it is a 30 foot run which requires that gauge of wire for 20 AMPs.

This stabilizer works very well. I replaced the original Lippert unit on my 2008 5th wheel as the parts I needed were no longer available. The original Lippert unit worked great until some idiot in a drunken stupor decided to move it with the stabilizer in the “down” position. I probably won’t do that again anytime soon. DOH!!!

The item was value priced compared to the competition so when it was on backorder from the manufacturer for 3 weeks I understood. When I placed my order with the seller I only paid for standard shipping but as soon as the item was received in the seller's warehouse it was shipped UPS next day (a $48 value). I suppose they elected the next day option to compensate for the 3 week manufacturer backorder delay. The item was received as described by the seller and I installed the item the next day. I rated this Excellent.

Did come with switch and circuit breake. I will keep for spare. No instructions of any kind and link on item does not exist. There was a link to a manual jack when I first looked. Simple enough to install without them. Did find color code and wiring diagram. Arrived within 3 days and only slight damage to 69 lb box. Still don’t clearly see how it will level unless RV is already mostly level. One motor, a split screw and assembly floats left/right in the top mounted track. Even though the legs can compensate for uneven ground at the lift, it will just elevate the RV as the same level as where it started. It doesn’t autolevel. Only took 5 minutes to bolt up as I temporarily wired and used the switch to raise into position. Running the wire and installing the electrical was more involved.
