Rear Setup/Dimensions?

2nd gen shock mounts are different so I am not sure about the lower mounts. 1st gens use the ubolt plates to double as a lower shock mount, so they cannot be reused.

For the angle of the shock it depends on how much travel you get in your springs and how much travel your shocks are. Example: if your leaf springs travel 18" and your shocks only travel 9" then you would have to put them at 45 degrees to let 9" shocks travel the full 18". The shock actually travels less but you have to bump up the valving so it can be as effective due to the extra leverage, so it gets hotter. Also an 18" shock would have more oil to keep it cooler. Ideally you would want the same travel shock and spring so you can mount them vertical and eliminate these issues

 

The main deciding factor was price, Also i need my bedspace. Engage is really close to me as well.
