rear ends.

That looks like a good and tight rear end..

 

You would have to pull the cover off that rear and check it out.

 

Rob, don't tell me that's your old lady.

Regardless, a good lube is essential when dealing with rears.

 

AMEN!!!

 

Preferably synthetic, less friction and lower temps.

 

LOL, not my girl. She'd kill me if I posted a pic of her. It WS just the 1st pic that came up on google

 

I would guess that is a high speed rear.

 

One thing to consider with ratios is the year and brand of engine. Older engines such as 2002 and back, especially mechanical engines from early 90's and back, are a high rpm engine, while today's engines run extremely low rpms for peak performance. This has to be factored in also. There is a lot to be taken into account when specing. As mentioned before, tire size, weight usually pulled, type of terrain, such as a lot of mountains or mostly flat land. Another biggie is the desired speed you wish to run most of the time. If you are running 55 mph back roads instead of 65 mph interstates, you will need to match ratios so you won't be changing gears on every slight rise in the road.

 

likely high maintenance too...
