This is a set of SOLID Rocker Spacers for the Ford FE engine.  Made from Premium, USA sourced T-6061 Mil Spec material. Precision Sized, Milled and Polished for performance. This set will fit both Adjustable and Non-Adjustable Rockers, and will prevent Lateral movement of the Rockers on the Rocker Shaft. Most FE engines will have at least 1 or 2 broken Springs on the Rocker assembly upon inspection, and those cause accelerated Guide, Stem, Seal and Tip wear due to lateral movement. How many miles(Decades) do your Shaft Springs have on them?? Simple installation, with a selection of Shims for a Custom fit on any OEM or Aftermarket Shaft typeRockers. Just remove the Springs and replace with the Spacers..then re-install.  Payment required within 10 days of auctions end.  Please see my other auctions for MANY MORE Ford HiPo parts. Questions?
