Description
High quality – made in America.
All pulleys are CNC-machined from aircraft-grade 6061-T6 aluminum.
Lighter and stronger pulleys.
Does not include a 1-inch shorter belt.
The smaller pulley requires much less work for your engine to turn,
giving you more horsepower to the powertrain — estimated 10–12 HP.
Add throttle response to your V-10 with our new
T6061 billet under-drive pulley! Machined in the USA from T6061 billet
aluminum, this pulley drops from the factory diameter to our under-drive
size, reducing the unnecessary amount of power sent to accessories, thus
adding free HP and improving quarter-mile times.
During testing, we have seen an average of 10–12 RWHP, and a tenth or
two quicker quarter-mile acceleration. This one-piece billet pulley comes
with new bolts (when necessary).
Use a 1-inch shorter belt (available from your local auto store – not included).
