Sure did, heaps better than the leaf setup.
There's the Performamce Suspension kit, wich isn't cheap ($4300) but it's all bolt in. It does need exhaust mods.
Or McDonald Bros racing make a weld in kit ($2500) but you have to remove the fuel tank as the links run between the chassis rails.
Just work out what height you want to go with before ordering a kit as they're usually pretty low.
