CIH competition rocker arms
Hello,
I'd like to share some information about our OPEL CIH competition rocker arms.
We have totally redesigned the CIH rocker arm system, with following highlights (indicated per intake / exhaust pair, in order of fitment):
- 2 threaded studs which replace the original studs
- 2 aluminum 7075-T6 rocker arms with steel pushrod insert
- 1 rocker arm shaft which is fitted on the threaded studs
- 2 custom nuts which lock down the complete system
- 2 valve adjusting screws (Mahle)
- 2 solid cam followers with dedicated coating
- 2 long pushrods (Manton)
-> the rocker arms will strictly rock, no side forces on the valve stems for aligning the rocker arm
-> the valve clearance is set by setting screws, not by a floating rocker arm shaft
-> long pushrods for reduced angular movement
-> lubrification through rocker arm shaft > rocker arm > pushrod > cam follower
-> no machining required: direct replacement of OE parts in the car by just removing the valve cover
-> currently tested to 8.500rpm
-> produced 100% in Germany
Price per pair (1 intake + 1 exhaust): €370 / $370
-> you need 4 pairs for a 4 cylinder engine
-> you need 6 pairs for a 6 cylinder engine
-> volume discounts available
We are fully aware that this is a lot of money. These parts have been designed, produced and validated in Belgium / Germany with the greatest possible care, and we have chosen to make a setup without compromises to obtain the best possible performance.
These parts are intended for competition use only and may not be street legal in your region.
You can browse our homepage "http://www.catcams.com" for camshafts, adjustable cam wheels and more valvetrain parts. Please feel free to share your thoughts.
Kind regards,
Ken Stessens
