Call or Text (352) 722-5295Lug nuts on the 2018-2023 Ram 1500 3.0L EcoDiesel
A lug nut has to get three things right. The thread has to match the wheel stud, the seat has to match the wheel, and it has to hold torque. Get the thread wrong and it won't start on the stud; get the seat wrong and it won't clamp the wheel properly. On this truck the years split across two bodies: the DS (2018 Ram 1500 and 2019 Ram 1500 Classic) and the DT (2020-2023 Ram 1500). The lug nut thread and seat spec isn't confirmed by a primary source for either body, so this page doesn't list one. Your truck is the reference.
Why owners buy a lug nut kit
Lug nuts on this page are about setup more than repair. A kit with wheel locks makes your wheels harder to walk off with. A black or silver finish matches the wheels you run. And a full set replaces nuts that are mismatched or damaged, so every wheel gets the same hardware. If none of that applies, the factory nuts on your truck are doing their job.
Factory nuts vs. an aftermarket kit
If you've lost a single nut, a factory replacement keeps things the way Ram built them. If you're replacing the whole set or adding locks, a kit gives you matching nuts and locks together. The trade-off is fitment certainty. A factory nut is made for your truck, while these kits are listed for 2014-2018 EcoDiesel trucks and need a check on later years.

Fitment notes
Before you order, compare a factory lug nut from your truck with the thread size in the kit's listing. If you run aftermarket wheels, match the seat to the wheel rather than to the factory nut. On a 2020-2023 truck, the DT body sits outside the kit's listed years, so that comparison isn't optional. When in doubt, verify by VIN or use the fitment checker on the product page.
Frequently asked questions
How do I check my lug nut size before ordering?
Pull one factory lug nut and compare its thread with the size in the kit's listing; a thread gauge or a parts counter will settle it. Check the seat shape against your wheel too. If you'd rather not guess, call us with your VIN.
Do these kits fit a 2018 Ram 1500 EcoDiesel?
A 2018 Ram 1500 falls inside Mishimoto's 2014-2018 3.0L EcoDiesel listing for both the black and the silver kit. If your truck wears aftermarket wheels, confirm the seat style matches those wheels before you install.
I have a 2019 EcoDiesel. Which truck is it?
It is a Ram 1500 Classic, the DS body carried over from 2018; the new-body 2019 Ram 1500 had no diesel option. These kits are listed through 2018, so compare a factory lug nut with the kit before you order.
