I liked my brute strength when I had a 12 bolt.

If it's a drag car, why bother with a differential? Just go with a full spool.

That's^ a very good point, but if you won't be trailering the car to the strip, or if you'll be driving it to any shows, cruise nights, or just romping around on the street once in awhile, then I'd have to say that the Detriot Locker would be the way to go since it's likely the most durable. There aren't any clutches, nor spider gears to wear out, and you can still negotiate turns w/out having to spin the tires through the turn, nor worry about breaking an axle like you might have to with a spool.

if the car won't see any street time at all though, then I agree..go spool

Thanks for your reply Steve. Well, drag radials never last very long on the street anyway. Even if a spool isn't used. I seem to remember somebody on here mentioning that they broke an axle while driving on the street with a spool. So that's why I brought it up, since it seemed believeable to me. However, I'll admit that I cannot speak from experience on the topic of spools being used on the street.

Thanks Billy. I have also heard others say you will break an axle by running a spool on the street. I haven't had any problems and had to ask when it came up again.:beers:

My old speed shop friend says a spool isn't ideal on the street but he ran his for over 10 years in his 12 second 69 Road Runner without a problem. He said the axles fail because of exceleration and tight turns around corners. He said he always stopped back enough to get some speed up going straight and then turned as wide as possible at a steady speed. He did say though tire wear is unavoidable with a spool.:)

Good stuff in this thread. I've always used Detroit Lockers for 4x4 offroad so I guess it makes since to use for the drag strip. Keep the commits coming.... =)

Ok I run a spool in my car on the street. drive 50 miles one way to the local drag strip race all day and drive it home. got a guy in the club with a 66 lemans with a mini spool beats the snot out of it on the street with a spool no broken parts as of yet. I know a few others local running spools on the street. My personal experiance is corners are slower. yes tire wear is more prevalent but if it is a drag car they wont last that long anyway if you burning them off right? enough said
