Approach/departure angles

Hello all,
The 4Runner has 9.6 inches of ground clearance 33/26-degree approach/departure angle; what would the approach/departure angle be with a 2.5" Front/1.5" rear lift?

 

Here's a protractor app if anyone with said lift wants to answer your question. Actually it's a handy tool for anyone with a lifted 4X4.

Good question! I was wondering the same thing. Did some triangle calculations. Stock:


Says that for a 33 degree angle at B, with 9.3 height, we've got 14.321" to work with. If we increase the length of AC to 11.8 (+2.5), we get the following triangle:


Which has an angle at B of 39 degrees. So there's a simple guess. It'd be better if someone who actually had the lift measured it - the 9.3" of ground clearance could be at a different location, such as between the wheels somewhere. So this could all be completely wrong ;-)

 

Nerd!!!

 

Since you're using TOYOTA's numbers as your basis........best guess, your numbers are good.

 

Thanks for the link and interest in the subject.

 

Thank you for your time and interest in the subject, will be close. Approach angle is most important in Rock-Crawling; 6 degrees difference is a lot when trails have high rocky ledges.
