Idler pulley

[kyhemi-dart]

I bought a car with a 2.76 pulley on it but there was no upper idler. what size do i need to put on? I know nothing upper the idler pulleys. Thanks

I'd put a 100mm idler up there. Might want to just consider a full 4 piece idler set. Lethal now has there own which have double bearings, or billetflow are a popular choice, which I have. They are single bearing idlers. Metco is another good brand.

You will also have to consider a different belt depending on which route you go.

I had the 4 piece billetflow idler pulley set when I had my 2.76 pulley. I have nothing bad to say about it.

whats the advantage to the 4 piece set as opposed to just an upper idler?

The advantage is that your idlers will not disintegrate like the stockers do.
