These USA made hub centric steel wheel spacers are the highest quality option we could source, and allow you to mount 35s or 37s on your factory dually wheels without the tires contacting. 

We offer these in 8x6.5 bolt pattern for 1994-2018 Ram 3500 dually trucks and 8x200 for 2019+ Ram 3500 dually trucks. We also offer these in 2" and 2.5" widths. 

If you're running a more narrow all terrain like a 11.5 or 12.5 wide Toyo AT or something without large side lugs, we recommend the 2" spacer. If you want a tire with a more aggressive side lug like a Toyo RT Pro, Nitto Ridge Grapplers, or Toyo MTs then the 2.5 spacers are the better choice. We do not recommend 13.5 tires.

We find the 1/4" inner shim is needed on most 2013+ Ram trucks, and especially needed with larger side lug tires. On older 1994-2012 trucks, you can get away without the shim in most cases.

Please note that you need to measure before ordering these. We are not responsible if your particular tire combo does not clear once these spacers are installed, and will not accept returns on installed spacers.
