Default Boring out throttle body
Hi all.
I've reached out to jeepersandcreepers.com and strokedjeep.com (Leigh Performance) and neither are boring out stock 4.0L throttle bodies any more. Is there anyone else that does this service? I've searched a ton and found a bunch of DIY but I don't have access to the proper machinery.

Thanks in advance.

I bought mine on EBay for my stroker. Has not given me any problems and I measured it to be sure. Just make sure its bored all the way through and includes a matching butterfly and you'll be good to go!

Oh, forgot to mention, I have a second throttle body I got from a yard already. I can always try to sell it and pick up an aftermarket or pre-bored one, but would be great to use it.

Do you need a stock one to replace it?

If I can't get this one bored out, or if I sell it I'd be interested. What would you want for it?

Buy it from strokedjeep.com. I got a 63mm for my 93. Great service, fast and made a huge improvement! Lower RPM on highway, no more struggling up hills on 32's, definitely more throttle response, and for some reason made it shift faster and smoother. Also shifting point dropped about 500 RPMs which was nice in my auto.

Details about Bore out your Jeep Throttle Body 4.0L to 62mm 2.5L violetkumlien

This guy did my TB and WOW. Fast and reliable. Plus you can't beat his price.

He is on Ebay by the way.

I'm having him do mine VERY soon! Does anyone know if you're putting a 99-04 intake manifold on a 98 head if you use the gaskets for a 98 or a 99?
