View Full Version : Underdrive Pulley kit

I am planning on installing a STEEDA underdrive pulley kit to my 99' Cobra and was wondering if it is a straight forward bolt on and go modification or is there any tunning involved.

No tuning required. It's very straight forward. You will need a Pulley Puller. Many auto parts stores rent them, if you don't already have one. Also, the alternater pulley is very difficult to remove without an impact wrench.

Make sure to re-check nut/bolt torques after a day or two.

Good Luck :thumbsup:

Thanks:thumbsup:. Are there particular torque settings or just tighten them, by the way do these underdrive pulleys make much of a difference.

No the pullies won't make any noticeable difference driving. A few Horsepower but when combined with other mods like headers, exhaust & K&N air filter they all begin to add up. :D
