Fitment Notes

  • 2WD Models Only!
  • Will NOT fit 1968-1972 Camper Special gas tanks.
  • Stock exhaust system will need to be modified to retain cat. converter
  • Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Ceramic coated headers require several heat cycles to fully cure before they will withstand extreme heat. Flowtech recommends using cast iron exhaust manifolds or old headers to break in new engines to avoid coating damage.
  • The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Flowtech does not recommend the use of header wraps as this will void the warranty.
  • On some models with the C-6 transmission, it may be necessary to bend the linkage arm on the transmission. Bend it 1/2” to 3/4” in towards the transmission and make an adjustment at the steering column. The included instructions will provide more details on this step.

Get yourself a spare set of mop cloths to keep your Roborock always ready to run
Size: Mop Cloth-5
Does the Roborock do a fantastic job mopping the floor? No, but it does a pretty good job, in fact β€œgood enough.” Even better, the Roborock mops the floor more frequently than I ever did so it stays cleaner, overall. Definitely get a pack of spare mop cloths so you can have a set being washed while another set is available to put on the mop. So far, none of the mop cloths have worn out. Given how long they’re lasting, I’m inclined to say it is a decent value for the price paid.

OEM Roborock Cleaning Pads - Do not buy the knock offs.
Size: Mop Cloth-4
These are Roborock OEM pads for my 10R. I tried many of the cheap knock offs and they were terrible. These work great. Highly recommend.
