Improved Racing oil cooler adapters have a low-profile for more header clearance. The adapters are machined from a single piece of billet aluminum and black anodized. For additional clearance with reliable sealing, they come with aluminum gaskets fitted with Viton® seals, and the adapter mounting holes are counter-bored so the mounting bolts fit flush with the adapter surface. Select Improved Racing oil cooler adapters are also available with a built-in thermostat. Oil coolers help prevent the oil from getting too hot, but are also prone to lowering oil temperatures too much, especially in colder weather or during highway driving. The rebuildable thermostat speeds warm-up and helps reduce engine wear and horsepower losses by preventing oil temperatures from dropping below optimal levels. Features and benefits * 100 percent bolt-on solution; no fabrication, bending, or line modification is required * Viton® seals throughout for maximum reliability * Oil exiting the adapter is filtered oil * 6061 T-6 billet aluminum construction with black MIL-A-8625 Type II anodized finish * Standard female -8 AN O-ring boss threads for optional anodized adapter fittings in your choice of -8 AN, -10 AN, or -12AN lines * Depending on application, includes port(s) for oil sensors or turbo oil supply * Includes all necessary hardware * Limited lifetime warranty

Milodon aftermarket main bearing caps not only strengthen factory 2-bolt blocks, but they will also add a measurable degree of strength to 4-bolt blocks. They are made from precision-machined, high-strength steel, which has the proper balance of strength and flexibility to allow for the transfer of increased shock loads to the crank and bearings. The secret is in the side bolts. They are angled so that they pull from the side walls of the block and not from the flimsy main web area. They'll also load the cap against the register step, which will prevent dreaded "cap walk." They can be installed by anyone with a hand drill and a tap and they come with the necessary bolts, washers, and drill bushing to complete the installation. Milodon main cap kits are available in your choice of angled or straight bolts.
