Description
The OTB Gear Muroc 1 Aluminum Radiator Cap is a show-quality dress-up accessory designed for traditional hot rods, customs, and vintage restomods.Named after California's historic Muroc Dry Lake—the legendary birthplace of early land-speed hot rod racing—this cap infuses an authentic 1940s retro aesthetic into your engine bay while delivering modern cooling system reliability.
1940s Retro Engineering & Styling
USA-Machined Billet Alloy: Every cap is precision CNC-machined from high-quality aircraft-grade aluminum alloy right here in the USA, then treated to a flawless, mirror-polished show finish.
Period-Correct Fin Design: Features a distinctively sculpted, single-ribbed aerodynamic raised fin that perfectly complements traditional multi-carbed flatheads, vintage valve covers, and nostalgic engine themes.
Premium Stant Internal Core: OTB Gear houses a heavy-duty, proven internal radiator cap manufactured by Stant Corporation beneath the beautiful outer shell, ensuring precision pressure management and a tight neck seal.
Two Crucial Pressure Ratings
The cap is available in two separate pressure variants to match your specific cooling loop architecture:
7 lb. Rating (Part # 6231): Ideal for low-pressure, vintage, or original copper-and-brass radiator systems that cannot safely handle high modern pressures without risking core seam failure.
