SLP Harmonic Balancer/Underdrive Pulley With Belt

SKU: 100235pack

This 25% underdrive balancer incorporates a number of high quality features you won't find on any other aftermarket unit and makes up to 9 additional rear wheel horsepower and 10 ft-lbs of rear wheel torque over the stock crankshaft pulley. Pulley features are a pair of extra tall belt retention walls that eliminate the belt slippage issues common with other balancers. Other unique design strengths include a 100% steel construction (other brands use aluminum), integral timing marks and built in puller mounting threads. Includes detailed installation instructions.

Features:
Up to 9 Rear Wheel Horsepower Increase Up to 10 ft-lbs. Rear Wheel Torque Increase Extra-tall belt-retention "walls"-no more thrown belts! 100% steel construction Lighter than the stock balancer Integral timing marks and puller-mounting threads Does not cause false knock retard or erratic power-curve dips.

Note: This package comes with the required belt.

PRICE: $229.99

Quick note, this balancer won't fit the 2009 models. SLP is working on one for that year now.

does this effect the a/c and alternator in any way
Not any that you will notice. they are both pcm controlled.

It will give you a couple seconds of low p/s on cold mornings but i mean exactly that, just a couple seconds and this is moreso in cold climates.



Tbryne- i highly suggest finding a way to sell that installer bolt too. It keeps people from beating the pulley on with a mallot until the o.e. bolt starts to thread.
The crank pulley bolt should be replaced. Does this bolt come with the pulley
