Ok I have been thinking about getting a lift kit for my 1994 f150 it has a L6 5 speed with overdrive and im sure its got granny gears (it aint fast but can go with 900lbs of stuff with ease in the back) I don't want to go all out and get a 6 inch lift for it i was thinking of at the most 4 inch lift for it. i do go off road for fun. so how bad is the power loss if i get a 4 inch lift and run 33s? any one have that set up? pictures would be cool too. this is what it looks like now. im running 31 inch tires and have about 5 inches of clearance to the bottom of the front axle case.

 

Just as a word of reference, my 300 is slow as sin, but it's the same whether I've got it bulldogged with over 1000 pounds in the back or unloaded.

But on to more pressing matters. A 4 inch and 33s would look great on your truck! You're going to want to re-gear to 3.73 or more better 4.10s for good power with those tires.

 

I was thinking of swaping out the gears even before getting a lift but thats out of my reach as of now its my daily driver and i dont have a good safe place to work on my truck What is the best gear for speed? i got to ask and id need to swap out the front ones too so its a weekend project if i get a place to work on it.

 

If you want all out top speed the lower the number gear the better (3.08 better than 4.10). But if you want better acceleration everywhere in the power band, and overall a much more responsive truck, you'd want the 4.10s instead of 3.08s. The higher number gears will cut your top speed a little but more than make up for it with the acceleration.

And if you're gonna run bigger tires, they reduce your gearing too. I have 3.08s, but with the bigger tires, the effective gear ratio that's getting to the ground is equivalent to if I had 2.80s in the rear end. 33s with a 3.55 rear gear effectively is a 3.10ish gear.

 

ok good to know id rather have acceleration then top speed ive alredy taken it up to 80 before. its the exeleration thats fun going over a small hill can you say air time haha thank you guys for the info
