For SBC, BBC. Distributor Gear Series:Carbon Ultra Poly. For Use With:Any. We do our best to display images of the actual product being sold. Occasionally, we use a universal image because the manufacturer has not supplied us with a photo.
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.
