What would you think a used set of these would be worth? They are in great condition. Are they any good also?

 

I'm running them on a cc306 stroker car and they are holding up great. Nice and fairly quite as well. From what I understand Crane makes them but I could be wrong. Either way they are maxed out a .575 lift if you want to put that in your description. Should be good for $100-$200 used.

 

Compare that Comp Pro Magnums are <$300 new and are a better rocker. Those would be ok used at the right price.

 

Pro mags are not a better rocker.

They are made by Crane, and are a very high quality racing rocker that hold's lash unlike the pro mag.

 

I agree the pro mags are noisey and need regular attention on the lash department.

 

Does anyone know what the max lift you can run on the pro mags?

 

The rocker you use doesn't have anything to do with how much lift your engine can handle (unless you're running some seriously ridiculous lift).

 

I guess everyone has an opinion. Never, ever a lash issue with my Pro Mags.

 

I like the comp stainless even better and the price is similar...13 years, 52,000 miles, countless 1/4 mile trips and never an issue...

I'm curious why this is. Not doubting your info, but doesn't the rocker nut determine how long the rocker will hold its preload? I mean, do they have bearing issues or something?

 

The trunnion step is too small and not hardened properly, and especially on solid roller applications the lash goes away as the trunnion and poly lock eat each other.

 

Also with a stronger spring pay attention to how much clearance the shaft of the rocker has around the stud too much wiggle and it can eat on your stud and eventually break, especially if your geometry is a little out of wack.

 

i have crane 1.6 s/a rockers on my car 4 years now (over 12 k miles)....never had to adjust them once since install. not very chatty either. barely tell they're there vs stock.
