86-91 RX-7 Complete Dual Drive Belt Pulley
Kit With Belts
This pulley kit replaces the alternator, the water pump pulley and
the main pulley. They free up horsepower (With our SR Underdrive
Dual Drive Belt Power Pulleys our Project RX-7
gained 10 horsepower.) due to being 45% lighter than stock
and by underdriving the crank shaft pulley, alternator and the water
pump to keep down the chance of cavatation.Our SR pulleys are also
larger than the competition's pulleys so the fan belts have a larger
surface contact area ( so our pulleys _won't slip_ on the
fan belt causing your rotary engine to overheat which is very common)
Available in black, blue, red and clear anodized hardcoated lightweight
and strong 6061-T6 billet aluminum for years of trouble free use.
Complete kit with everything needed. A very easy horsepower increase
and nice looking addition to your Mazda RX-7. Simple to install
with hand tools.
Note: Our SR
pulley kits do not require you to remove the crank shaft
hub in order to install the main pulley ( like some other pulleys
) which is a very _difficult_ thing to do.)
Complete Underdrive Pulley Kit Includes: Alternator pulley,
waterpump pulley and main drive crank pulley kit. 2 new fan belts
and all needed hardware.
Red , Blue, Black
and Silver colors.
