I am looking for a two- to four-bike rack to be attached via receiver hitch. I would appreciate any suggestions. Thanks!
I have the Quadratec ones. Works pretty well plus they have a discount for forum members I believe. Just PM the Quadratec account on here and they'll give you a quote with the discount. https://www.quadratec.com/p/quadratec/2-bike-folding-bike-rack-2-receiver-hitch-bolt-cable-lock https://www.quadratec.com/p/quadratec/4-bike-folding-bike-rack-2-receiver-hitch-bolt-cable-lock
The 1 Up racks are great, and will fold up. But they are expensive! https://www.1up-usa.com/product-category/bike-racks/
I also use a Quadratec rack (on my JK), but I have a VersaHitch version. It's heavy, but pretty solid.
I use the Thule on mine, and it works great. It also tilts down. If you email them, and if you are/were Military, they will give you a 50% off coupon. No questions or proof needed.
I just bought the Yakima HoldUp 2 and a 7" hitch extender. The extender is needed for the rack to clear the spare tire and even though the first thing in the instructions is "Do Not Use with Extender" it seems very secure. A potentially big drawback is that even though you are able to tilt the rack downwards from level, you can only open up the rear door about a foot. With a hardtop 2-door, this makes getting cargo out a pain.
I have this one. Allen Sports S645 https://www.amazon.com/gp/product/B00C45IBCS/ref=ppx_yo_dt_b_asin_title_o00__o00_s00?ie=UTF8&psc=1
If you ever want/need to use rack for off road use I would recommend ISI racks, post 198 in link below. Holds them up high and SOLID, absolutely no wobble of rack in hitch or bikes on rack in any terrain. https://www.jlwranglerforums.com/forum/threads/bike-rack-options.3426/page-14
Have the Kuat unit as well. Had to get the Kuat extension for the receiver to push the bikes out past the rear tire. With the Kuat extension you can put it in up or down which will lower the bike rack enough so you can open the rear door/hatch if needed.
