GORILLA-LIFT® is fully adjustable; lighter weight tailgates will not pop up off the ground and heavier tailgates will not fall to the ground. When properly adjusted most tailgates will float up and down and stay in any position that you leave them.

GORILLA-LIFT® fully encloses the lifting system. This is a very important design feature which helps to prevent injuries and also keeps people from getting a finger, hand, or any other item caught in the lifting system.

GORILLA-LIFT® is a two-sided tailgate lift assist; it attaches to both sides of the tailgate. This prevents tailgates from warping or the hinges from deteriorating prematurely from uneven stresses. This also helps to prevent the full weight of the tailgate from smashing down in the event one side were ever to fail.

Yes, you must always do so! GORILLA-LIFT® does not lock the tailgate in its upright position.

It is 2 inches high, 2 inches wide, and 72 inches long.

Normally it will take between 30 and 60 minutes. Remember every trailer and tailgate is different! Please refer to our Instructions for more information.

Please email us at [email protected]. We will be glad to discuss the possibility with you and are always looking for distributors and dealers in new areas, both nationally as well as internationally.

There is a work-around though.  You can use either L Brackets or Angle Iron to attach the housings to the outside of your side rails below 24 inches from your trailer bed.  You’ll need to keep the housings in the same orientation as they would be when mounted to the top of side rails. Please see photos below.

Yes, but you’ll need to make sure the housings are straight, level, and flush.  If the top of your trailer’s side rail is made of round tubing larger than 2-inches in diameter, you will either need longer mounting bolts before beginning installation or you can spot-weld the GORILLA-LIFT® on the side rails instead of using mounting bolts.

We also now sell Extension Roller Assemblies that allow the GORILLA-LIFT® to be mounted 3 to 6 inches back from the edge of your side rails. You can find more information here and view the instructions here.

Every trailer manufacturer makes their trailers a little differently, therefore we have supplied hardware which will work with most. In some instances, you may have to go to a hardware store and purchase longer bolts to accommodate your trailer’s side rails. If a bolt is too long you can always cut it off.

IMPORTANT: Always use the supplied bolts to attach the assist’s cables to your tailgate!

Be sure you are using needle nose pliers, and as you push the ring on the pin gently rock it back and forth.

Check to see if the angled ends of your housing were bent during shipping; these ends must be straight. Check to see if any burrs or rough spots were overlooked on inside of housing during manufacturing and smooth them down.

Change the direction of your pins to where the locking rings are on the opposite side of the housing.
