I was wondering if anyone could tell me which metric sterring box has the best ratio?

Thanks in advance.

the z28 or trans am box is what most guys are running if you can't use a quick steer. they're getting hard to come by at salvages, but i believe you can still get remanufactured ones.

Use a box off a Jeep Cherokee. Bolts right up, 3 turns lock-2-lock.

If NAPA online's sellin em for $135, buy it there.. The yards around here have been known to charge as much as $300 for a 2 1/4-turn z-box. They never got into my pocket, but I know guys that actually paid it.
If you can't afford that, your next best bet's to go to the junkyard and just turn the input shaft of a bunch of boxes til you find one that's 3 turns or less. They're pretty common at 3 turns. Used on everything from Jeeps to Caddys to s-10 pickups. Saginaw made the boxes for **** near everything for quite a while, and they're all pretty much interchangeable as far as the bolt patterns and output shaft splines go, but you have to make sure to check for the right style of input shaft spline and the right style of hose fitting. The input shaft is one of 2 different spline counts. The hose fittings will be either a compression style or an O-ring style, but you can buy adapters to go from one to the other, either way.

Good Luck,
Matt
