PN: 12200 Distributor Gear Material:Carbon Ultra-PolyDrilling Required:Yes Roll Pin Included:No Quantity:Sold individually. COMP Cams composite distributor gears are manufactured from Carbon Ultra-Poly composite to ensure superior strength and less wear. They are the latest in high-tech distributor gears designed around solving the wear issues associated with bronze gears in racing applications. The polymer gears are ideal for street roller applications--they feature virtually no wear, and they eliminate the problem of spark scatter that's associated with worn bronze gears. The gears have undergone stringent testing in various applications with positive results.
Only time will tell if it holds up better than bronze.
I purchased this for my boat engine (383 sbc stroker w/roller cam) to avoid having to replace bronze gears as many bronze gears wear out and need to be checked regularly.
A must for roller cams and if it last 3 times longer as suggested, it’s worth the cost with extend gear life and avoid the extra maintenance, especially with a water craft.
Time will tell.
(Check your distributor shaft size, they do vary).
Life’s grand. A grand here and a grand there.
