Allstar Performance Oil Restrictors — Dart/SHP SBC .090in Pair | ALL90072 1976-chevrolet-k20-suburban-esi3602509 Corrosion resistant aluminum constructionAllstar Performance oil restrictors reduce oil flow to the top end of the priority main oil system on Dart and Chevrolet SHP small block engines, forcing more oil to the main and rod bearings and reducing the risk of emptying the oil pan during sustained high rpm operation. Each aluminum restrictor uses an Allen head design with a . 090 in inside diameter hole. Sold as a pair, the set includes an extra O ring seal and installation instructions. FAQ
