Most RRs are sold with the poly-locks, Summit probably sells them separately. You could go to the Comp Cams website and get a P/N for them.

ah, thanks don 97 ss.

summit has the parts I need. I bought a hotcam kit, ruined the polylocks (long story), and bought replacement 3/8" polylocks from mr. gasket. However, they suck *** - the nut itself seems to be made from brass or something. They *kept* coming loose, time after time, no matter how tight I did it. The bottom had pieces chipped off when I took them out, and some of them, I torqued too much and the nut just snapped in half.

don't buy mr. gasket polylocks! I wasted $46 on them.
