Question:
Gear ratios with factory tow package versus standard gear ratio?
asked by: Bill
Expert Reply:
I tracked down an online version of the owner's manual for the 2015 Jeep Grand Cherokee, and while it doesn't mention specific gear ratios, I was able to find the various towing capacities based on engine size and drivetrain. The manual doesn't separate tow ratings based on whether or not the Jeep has the factory tow packages. It lists the following specs:
Jeep Grand Cherokee with 3.6L engine, 4x2 or 4x4 model - Max Trailer Weight: 6,200 pounds
Jeep Grand Cherokee with 5.7L engine, 4x2 model - Max Trailer Weight 7,400 pounds
Jeep Grand Cherokee with 5.7L engine, 4x4 model - Max Trailer Weight 7,200 pounds
I recommend verifying this info in your copy of the manual or by checking with a local Jeep dealer. Your local dealer may also have more insight into the specific gear ratios.
If you still need a trailer hitch for your Jeep Grand Cherokee I recommend the etrailer.com # e98901, which features a 6,000 pound towing capacity (or 7,500 pounds when used with a weight distribution system) and a unique matte black finish for a rugged, scratch resistant surface. This is the highest rated hitch we have available for your Jeep and it will line right up to existing holes in the frame rails for a simple bolt-on application.
I have attached an installation video you can use for reference.
For a wiring harness (if the Jeep doesn't have the factory tow package which would include one) the Tekonsha T-One # 118727 will work perfectly. It will plug into factory ports behind the tail lights to provide you with a 4-Way to connect with and power a trailer's basic signal lights.
I have again attached an installation video that you can follow along with.
I have lastly included a great article below that explains how to choose the right ball mount for towing that you can look through if you don't have one already.
