Anyone who is running a stock D44 or D30 should sleeve and gusset it if the wheel it After 37s. Hell even after 35s. And for people who don't think d30 are he same then why the hell are the sleeves and gussets you buy from Evo or any other company the exact same size. They will fit both axles. Trade the dude. You will love them. But then again be carefully wheeling it. And that goes for you d44 guys too. Here's a pic or two of mine. Nothing except for the spring perches are factory. All custom built.
