I have a 1967 chevy truck. Im tired of spinning one tire. Should I go with the easy locker or a posi unit, and why? I drive the truck mabey once a month. ---

It is also dangerous. Ill spin the one tire and sometimes the other will catch and sling the rear around. Just looking for advice. ---

Also I need some traction. With 500hp I stop at a red light and when I go to take off I spin a tire or always catch a second. I think a locker or posi would help that. I have heard off alot of of roaders using lockers, just wandering if it would be right for the street. It is a little cheaper than puttting a posi in. ---

If you got a differential lock, for how long or how much of your driving would you plan to keep it engaged? ---

Well with the detroit easy locker it rathcets so it will only be engaged when in power. ---

> it will only be engaged when in power. So if you’re accelerating in a turn with both rear wheels in your pickup locked together, aren’t you worried that 500hp will cause them to spin (allowing lateral forces to happily take over)? ---

nevermind. I got my question answered by calling eaton. They have a trutrac locker that only fully locks when going straight and adjust for cornering. Mabey you should do your homework before responding. They have a great website and customer help line if you have any more questions like this you need to answer. Better luck helping someone else! ---

I have a Powertrax No-Slip locker in my Bronco. It’s very streetable. You could also go with a selectable air locker or an e-locker that offers on-demand traction, you engage and disengage it via switch. ---

Wow. Talk about a temper. The people in this forum are voluntarily trying to help, and you’re ripping into him like he just kicked your dog. By the way, how about accelerating from a stop GENTLY, instead of mashing on it hard enough to spin? It doesn’t matter if you’ve got 500 HP or 5,000 HP; less pedal = no spinning, whether it’s a posi/locker/spool, or one-leg rear. ---

While automatic lockers are designed to disengage when cornering, I believe for some models that’s only true to a point - and re-engagement will occur at heavy throttle. Is anyone out there familiar with this behavior? ---

Street rods are sagas of epochal proportion. On the last page he walks home broke. ---

While all of you have questions and comments, you have still not helped answer a question I asked. I have since joined a forum where people really now what they r talking about. I can apply very little pedel but I still get spin ( because of the amount of hp and torque with the lack of traction). Therefore I was looking for guidence help for the right solution. I got angered when all I got were pety stupid remarks like yours! ---

Come on . . . do you really think you’re the only person in this forum that’s ever driven a car with big power? Get real. We’ve all had wild cars with big HP numbers. 500 HP isn’t even a big deal anymore in a street car. Unless you’re driving on an oil slick, tire spin is from TOO MUCH THROTTLE. Drive away from a stop like there’s a cop behind you, and I guarantee no tire spin.
