Webb Wheel Products has released a 16.5 in. by 8.62 in. brake drum for R-series drive axles and TN and TP trailer axle applications.
This aftermarket drum, which carries Part Number 66855B, is similar to the Webb 66854B without an oil groove machined in the wraparound area, Webb said.
The drum will fit most applications where the 66854B is used, said the manufacturer. Weighing 122 lbs., the 10-hole drum comes with an 8.78 in. pilot diameter and 11.25 in. bolt circle diameter.
