Man O-War Ampco 45 Sleeves
Celebrating 46 Years of "Pure Performance" in 2026, Wisconsin based Darkhorse Motor Co says that "Milwaukee 8 platform exhaust lifter bores can wear quickly due to greater pushrod angles. With more aggressive cam combinations and higher valve spring rates the service life of the lifter bore can diminish even faster.
"Darkhorse Motor Co has a full complement of sleeves to repair the entire surface and properly reset to OEM tolerances. Our Man O-War Motor products billet Ampco 45 Sleeves have greater lubricity than the parent material and are considerably more wear resistant than any other product on the market."
