I agree with the above that you'll increase wear on the CV axles.  But otherwise a 2 1/2" lift on a Ridgeline won't cause too much trouble; though I wouldn't go any higher than that.

Most of the differences will be somewhat subtle.  Obviously center of gravity will be higher.  Raising the body gives you room for bigger tires.  But in a spacer lift, the undercarriage is not higher, so unless you put on bigger tires, the practical gains in ground clearance will be minor.

do you think I have anything to worry about on excessive wear on other parts or anything else on that matter 

Aside from voiding your warranty, it will kill your CV axles due to the extreme angles they'll be subject to that they are not designed for. If one just has to have a lift kit those are best used on vehicles with solid axles front and rear such as the Jeep Wrangler.

Honda doesn't make an actual pickup truck, the Ridgeline isn't a true pickup. It's a unibody that's styled like a truck. It's front-wheel-drive. In a true truck, the frame and body are separate features, where as yours, the body is the frame. They're made for very light duty things. Traditional pickups are also rear-wheel drive, and they have solid axle rear ends with leaf springs.

I highly frown on them myself (I have a minor in mechanical engineering), but you can lift actual pickups an inch or two and remain relatively ok. The lift also puts added stress on the vehicle's drivetrain, but but it's mainly the driveshaft, which is made of metal, not rubber boots retaining grease. Every time the car's wheels make one complete turn, the boot goes from tension, back to compression again; it's supposed to remain relatively straight. 

Thank you for all your responses 

I forgot to add it comes with spacers for the subframe to recalibrate the angles does that make it better?
