RPM gauge/Tachometer

[Jackrabbit41]

So I know this is a beaten to death topic, but like always I have many questions still.

 

I haven't wanted a tach until now because after I went with 4.10s and 33s, the comanche is a little slower. On the freeway going about 60, i really cannot tell if my rpm's are good or too high. Usually I'm pretty good at telling, because i can hear the exhaust, but I just can't tell. I also would like the newer cluster so that I could upgrade to some sweet gauge backgrounds. Right now i just have the speedo and the gas gauge as my 2 big main gauges. thanks

I promise, with 4.10s and 33s they are definitely not  "too high".  :thumbsup:

 

but back to the question, all you need is an 87-90 cluster with tach and then swap your oil pressure and coolant temp switches for sending units so those guages work.  :thumbsup:

Sub'd, I've been looking for a tach as well...

84-86 will also work if you do some swapping of the speedo gear clips but a cluster from a 4banger will need tweaking of the tach to be right for a 6.

Just to give an idea...I have 4.10s and 32s on my 98 4.0 ax15 4x4 and at 2500 rpms I'm at 70mph...

Thanks, makes me feel a lot better about it.

With 4.10s and 33s, at 60 MPH the engine is only spinning at 1965 RPM. That's not anything to be concerned about.

If mine has gauges already, do I still need to replace the senders if I get a newer tach equipped cluster? What is the newest cluster I can swap into the 'manche?
