Can anyone tell me about underdrive pulleys for the ram Hemi??? Good bad ???

 

I have heard NOTHING good about the HEMI pulley... I know I helped a freind install his and it was a PITA to get on and even worse when we removed it... It had a wabble to it and it also leaked oil... as soon as we reinstalled the stock pulley the leak was gone. Also there has been a string of TONER RINGS failing... and I think 9 out of 10 of them has an underdrive pulley. So I personaly would not recomend it for the HEMI YET...

I have one on my 4.7L and I have had ZERO problems since we worked with ASP helping them identify an issue, they modified the original design and fixed the issue so now the 4.7L Pulleys are fine and I would recomend it to anyone who has a 4.7L.

SPEED SAFE, AIR RAM

 

Thanks for the info... I think I will wait to see if anything better comes out....

 

I got my MotoBlue pulley last week. Hopefully I'll get it on in a few days, and see what the results are.
