Do you want to side load your spring and gain a 1/2" of tire clearance, or would you like to gain a 1/2" of clearance without side loading your spring?
What tires can I use on my rim?
I don't care WHO says the MP kit can get you a 3/4" offset, they're wrong. Doesn't matter how much they stop their feet and yell. The front hanger can only move a 1/2" before it hits the frame rail. If you put the MP and Dr.Diff spring hangers side by side (as I have), it's very easy to see that they move the front of the spring the same amount. Because again, the FRAME is in the way. The rear shackles of the MP kit are a 3/4" offset. If you offset the spring perches 3/4", you just put a 1/4" of bind in the front half of the spring. Your tire clearance doesn't change a lick compared to the Dr.Diff kit, it's still about a 1/2". And regardless, the limiting factor will be the inner tub of the factory wheel well, not the spring.
Do what you want, use whatever fuzzy math you'd like or believe whatever marketing gimmick best suits you, your actual tire clearance is gonna end up the same. The Dr.Diff kit is a higher quality, heavier duty kit and will get you as much extra clearance to the springs as you can get without a full 3" relocation.
