Additional Information

Did your International Harvester muffler give up on you? We're here to help. Our replacement 398511R1 muffler is built tough and fits more than one tractor, including the International Harvester 706, International Harvester 756, and International Harvester 856. We strive to keep your International Harvester running for the long term, which is why we sell quality mufflers that are built to last.

Whether you have the 706, the 756, or something else, International Harvester mufflers are expensive and thats why we sell mufflers direct at significantly lower prices than your International Harvester dealer. You can save up to 70% with TractorJoe.

Price is just one part of the equation though- quality matters too. We don't want you replacing your muffler more than you need to, which is why we back our parts with an industry leading warranty. Even if your 706, 756, or 856 is not your main tractor, TractorJoe knows that having it up and running is always important.

It doesn't matter if you're installing our muffler in your International Harvester 706, International Harvester 756, or something else, we'll be here for you. Our staff knows a lot about International Harvester tractors, and our Q and A community is there for any other questions you may have.

Frequently Asked Questions
When will I get my items?
Once your items have shipped it takes around 2 to 4 days to arrive at your location. You can track the shipment to find the expected delivery date or if there are any issues that have caused a shipping delay. Destinations outside the continental US will take additional time for delivery.
What if I will not be available to receive my shipment?
We've got you covered! Delivery carriers will generally let you leave a signed note on your door with instructions. UPS will generally leave a ground shipment at the door in rural and suburban locations without a note. You can also instruct the UPS driver to take it back to the customer service center for pickup if you do not want it left. For detailed information please contact the delivery carrier.
Can you ship to an APO/FPO address?
We unfortunately are no longer able to ship to AFO/FPO addresses.
How much is shipping?
Shipping costs vary based on product weights and where you're sending it to. You can calculate shipping costs in the shopping cart or checkout page.
