Timing Belt Tensioner Question

[AUTOBOT_SPECV]

Here is a kit I'm putting on

Is your timing kit already installed on the car? If not, could you do me a favor and tell me if that black pulley in the pic is made out of aluminum or plastic? Thanks!

All pulleys are plastic! The only wear parts are the bearings in the pulleys

Thanks! I know there is a manufacturer that makes those black pulleys in aluminum. I'm trying to figure out which brand does it. If anyone on here knows the manufacturer that makes the tensioner and idler pulleys out of aluminum. Please let us know! Thanks!
