First step to increase low-end torque?

Timco, while gear ratios are relevant to acceleration, it has nothing to do with HP/torque, only how at hp/torque is applied to the road. I don't see how you top speed in every gear is even relevant.

I understand this, but was saying that 2nd, 3rd, and so on feel much faster. Yes, top speed is irrelevant. Wrong way to say it. I'm talking 3k and under, or off the line power. Small add ons or upgrades are great, but I'm not swapping my exhaust quite yet!

Low end torque?? 4.0L motor.

I suspect most inexpensive bolt-on mods will leave you highly unsatisfied. Good luck in your search.

I was under the impression that it was not good for these motors to drive them at low RPMs. Keep it above 3000 is what I have read.

Agreed, but getting there is what I was wondering about.

Shift at 3,500-4,000 or more and don't let RPMs drop below 3,000.

Well, if it ain't there........

It ain't there......

you should at very least delete your secondary cats . that and a BMC air filter gave me a good boost in power and much more so in the upper revs. I did not notice much gain with the pulley. believe it or not but replacing my rear wheel bearings gave me a good boost .

Now, keep in mind I have NOT done a proper search, but is there a straight pipe that replaces the secondary cats? I was unaware that there were two sets. Easy job? I'll do the pulley soon enough, and de-snork or go big air filter, but this cat thing sounds doable!

My new bearings made my car feel slippery as it glides along the road. Just because they don't grind and howl doesn't mean they're not loud or stiff.

there are several brands of delete pipes out there. It is a fairly straight forward job. if bolts and clamps are not to rusted it is very easy.

There is no substitute for cubes if you are after torque. Everything else is miniscule and the costs can lead you to the poorhouse.

Some options
