Mopar Roller Rockers?

Summitracing.com part #DCC-4529885. These are mopar performance roller-rockers for a 4.0 at what seems to be a very resonable price. Is this the real deal?

The Yella Terra YT6627 roller rockers are much cheaper and fit under the stock valve cover. You can buy them from Quadratec.

Re: Mopar Roller Rockers?

very little, but the reduced weight and friction in the valvetrain is always a good thing. as with all mods, it needs to be coupled with other mods to see its potential.
