Cool piece but didn’t change volts during pass at 6500rpm plus
Jimmy S.
Fast shipping and was kept updated.
Terry B.
Fit perfectly and works great!

New pulley slowed my factory 145 amp LS alternator down perfect. Went from a 2.25" to this 3", alternator still charges perfect at idle and after letting it sing!
Josh W.
Looks absolutely killer, and I trust that this will keep me from having voltage drop issues, hopefully! Thanks guys for all the help also!!
Robert D.
Went on without any issues. Looks great.
TIMOTHY B.
Awesome product. Fixed my over spinning issues that I’ve been fighting for months.
Preston S.
Very easy to install! Hit it with an impact, old pulley comes off new one slides on! Don’t forget to measure backspacing of stock pulley before you remove. Super quality part!!
Sam T.
Great parts
Just what I needed
Josh P.
Excellent quality as always. Super easy to install, zip the nut off with an impact and the pulley comes right off. Did a Katech belt tensioner at the same time and just went to Napa to get a new belt.
Hugo L.
Real good product, I’m shifting at 7500 and keeps charging never drops voltage. Idle is at 14.3 never drops even with a system
Michael M.
I called an talked to Levi about how much hp I’d be pushing. And I needed to address the alt pulley. To help with future alt problems.
Jose S.
This is exactly what I needed and customer service is always great!

It seems to be performing as advertised, really easy install and it looks great see it for your self https://youtu.be/jdq7ZC11phM

I didn't have a charging issue, but wanted a larger diameter pulley because I was in between belt sizes to get proper tension. This made the difference between either breaking belts, or loose, slipping belts costing me boost. This was much easier than having to spend $1000+ for an 8 or 10 rib upgrade. Voltage hasn't suffered either, which was something I was slightly worried about.
Chuck S.
Fit as expected. Kept my alternator happy and it looks trick
Joshua M.
Worked perfectly to keep voltage going strong above 7000 rpm. Super easy install and perfect quality.
Charles t.
Seem to be the same but on the higher rpm i noticed no volt dip.
sean m.
I messaged Dalton about my charging issue. I had another “KRC 3.5” from Amazon. It wasn’t charging at idle. He explained that 3.5 is too big for stock size crank pulley.
He recommended the 3” pulley.
Boom my car charges at idle!
Took 5 minutes to change out.
Awesome part and awesome guy!!!
Erich H.
Awesome fitment, went right on. Fast shipping with a surprise in the box. You guys are the best. Can't wait to afford a cleetus wheel and quick release for it too. Thank you again.
jeff b.
Works as it should was able to install without getting a larger belt .
Debra K.
Brought this for my son’s car. It works great. Recommend it.
JAMES M.
Great product worked great
Brian G.
I purchased this pulley to slow the alternator down. On a pass the voltage would drop after 5200 rpm . After I stalling the pulley the voltage maintains as it should. Nicey made product !
Jeremy H.
Love the products and the quality of them. Top quality at reasonable prices. I haven't seen a single flaw in any of the finishes of any part I've bought. Keep up the good work guys. Very happy to be a motion customer.
Daniel M.
Excellent product!!! This pulley is worth every red cent! Works perfectly and not to hard on the eyes either. Thanks Motion you guys rule!
Tom D.
Very easy to install and calculate and should hopefully provide long life to my stock alternator. Motion Raceworks rocks!
PATRICK H.
Put the 3in pulley onto a Power master 180amp alternator and in installed into a 2005 sierra with stock truck accessories which required a longer 94in belt. I've previously killed 2 acdelco alts revving my 408 ls2 out to 6800, this setup got it charging right back at 14.3v
Zachary G.
Works as advertised.
Jermaine T.
Works as it should!
Steve F.
Fits great. Looks great. Works great. I was going through alternators then found this pulley solved the problem.
Nicholas P.
Perfectly made and slows my alternator down at high rpms
Donald E.
Fixed my voltage issues I was having above 7000 rpm on a sock alternator.
Michael B.
Kept blowing up alternators spinning the motor over 7k. Powermaster recommended their oversized pulley to fix the issue, but nobody had one in stock. Then I found this BEAUTIFUL piece which solved my problem. Also didn’t affect charging at idle at all (although my motor idles around 1k), the alternator still puts out 14.2 volts on average. Best purchase I’ve made in a long time, thanks again!
John M.
I ordered this for my 2017 camaro ss and it fits fine so it works on LT too just need to buy a nut for it
nicholas B.
For truck accessories ensure you have the larger idler pulley or the belt could contact the alternator mounting bolt. Nice part that helped slow down the alternator.
Brady M.
Works and fits great, less belt slip and less change of biting up an alternator because of higher rpm’s.
matt o.
Awesome products as always, highly recommend!
alexander h.
3 inch Billet alternator pulley. Easy install, Another quality product from Motion raceworks!!!
Donavon L.
Fixed my charging issues around 7 to 8k rpm... fits perfect, super easy install
Forest L.
Top notch quality, excellent fitment and does what it was meant to. Looks great as well!
Joseph H.
Used supplied shim and it fits perfect and looks amazing. Best of all it’s made in the USA!!!
