I am able to offer various billet aluminium pulleys.
All are machined from high grade 6063T6 aluminium, so very strong and hardwearing.
Poly vee pulleys are a speciality
Alternator pulleys from £45
Water pump pulleys from £75
Crank pulleys from £125
Idler pulleys inc bearings and spacers (steel only!) from £30
Crank pulleys can include a keyway cut if required - but at addtional cost.
Lead times are around 3 weeks for pulleys.
