just wondering some pros and cons of straight axle and IRS
this truck will be bagged btw.
id like to use IRS, just because when you lay out it will have 4wheel negative camber but idk if having bags will cause it to bind and eventually break things

 

Personally I don't care for the "broken axle" look of trucks when set on the ground, but to each is own.

From a driveline point of view, each joint is meant to rotate in a certain angle and if you run it at severe angles then you set yourself up for some serious wear or vibration. Yes, they travel to extremes, but they are not meant for continued use in those extremes. Tire wear is another thing also.

Just some thoughts from an outsider.

 

Not even a choice, use the IRS. Weight transfer, roll center, instant center, center of gravity, geometry, adjustability, heck, everything is better with IRS.

 

If you are actually going to "use" the suspension then it's great(road race, etc). Have it set up for one height and go for it. If you are going to raise/lower it for different "looks" then I resort back to the issues I mentioned.
