Pro Comp MX2.0R resi shock

[magic carpet XLT]

i run edelbrock 2.0s in the back, they are pretty much the same as pro comps but with a different name on them. it sure is nice to be able to mess with the valving on them. the price was even better at just $40. the machine quality is pretty good, i find it weird that there is just 5 shims on either side of the piston, as opposed to fox where there is 7-8+.

as far as FOA goes, their machining quality and tolerances just seem to be a little sub par IMO. take apart a FOX, then go take apart an FOA and you will see why they charge so much less (and consequently, why half the people you talk to have problems with them). the problem is, tiny variations in tolerances make a world of difference when you are talking shocks.

Edelbrock put way more engineering into their shock than fox did but they are for a different end user. Number of shims doesnt mean a thing if tuned properly. Some OEM's I have worked with have 3 or less on certain valve codes.
