Duratec Idler Pulley Kits
The Raceline idler pulley kit locates above the water pump to allow the water pump to be driven by the back of a 6-groove alternator belt. The mounting bracket is machined from billet aluminium, black anodized, and holds the off-set adjuster/tensioner on which the grooved pulley locates. The idler kit comes complete with the pulley and fittings to meet the block.
