I installed the Safari Guard hitch recently onto my LR4.
Very solid. About
4 inches higher and 4 inches rearward (watch your knees!). My bike rack has no issues with the length of the receiver or hole placement for the pin.
Couple of notes:
1. I needed to clean up the inside of the tow loop a little bit for the aluminum bushing. I had read to remove 1mm from bushing. That was not necessary. 20 seconds with a Dremel and sanding wheel and it fit perfectly. They may have updated the dimensions of the bushing.
2. Insert the bolts nearest the spare from the top. The bolt was a bit too long to fit when installing with the nut on top. Lowering the spare will make things easier.
3. With parking sensors, I needed to cover the two inner sensors with electrical tape.
If anyone wants a very good condition, new style OEM removeable hitch (two keys). I'm in the Los Angeles/Pasadena area. Or if you're in the area and would like to see the SG Hitch in person, let me know.
