Easy install for quick gain in hp I’d recommend a lower degree thermostat and make sure you order the proper belt size

Pulley slaps right in a lot lighter then OEM product. Noticed different idle and faster throttle response would definitely recommend one of these bad boys

Very light weight when compared to stock pulley! Only needed to go 1/2 inch bigger in belt size. Idle has improved as well as revs and slight pull when accelerating. Didn’t get 5*s because it had some couple jagged edges where the belt lays that needed to be ground down, but it a very nice item.

Great product light weight. The car response is much better now. A mod that truly works and only takes 15 mins to install. Didn't notice a increase in temp at all.

Very fast shipping along with the other pulleys I ordered. Very easy install, about 10 mins total doing the alt under drive pulley and 3.5" idler pulley. Noticed a very small increase in coolant temp but nothing major.
