I Have a 94 f150 with a striaght 6 and a 5 speed and i was wondering if you can buy kits to install LS or if you have to completely change the rearend

thanks

 

I'm assuming that your truck has the 8.8 rearend. You can purchase LS for that rearend and you can even go with a locker. Depending on what type of driving you mostly do, will depend on if you want the LS or locker. The locker will give you a lot better traction, but is a little noisy. To answer your question, yes, you can purchase a LS for that rearend. Hope this helps.
