DNJ® Valve Lifters are precision-engineered components designed to convert camshaft rotation into the linear motion required to operate engine intake and exhaust valves. Available in hydraulic, mechanical (solid), and roller types, each DNJ® lifter is meticulously crafted to ensure proper valve timing, optimal performance, and quiet operation. Every unit is manufactured to meet or exceed OEM quality standards, making DNJ® the reliable choice for professional engine rebuilds and maintenance.
DNJ® Valve Lifters are constructed from high-quality materials to deliver strength, durability, and reliable performance under tough engine conditions. The lifter body is made of hardened alloy steel or chilled cast iron for superior wear resistance. Hydraulic lifters feature a precision-machined steel plunger and corrosion-resistant check valve to maintain oil pressure and lash adjustment. A high-tensile spring ensures consistent operation, while the hardened steel or powdered metal pushrod seat handles force transmission. Roller lifters include case-hardened steel wheels and precision-ground alloy axles for smooth, low-friction performance and long-term durability.
DNJ® also offers a wide range of related components to complete your engine rebuild, including DNJ® Valve Lifter Kits and other essential valve train parts. These complementary products are engineered with the same commitment to quality, compatibility, and performance that professionals have come to expect from DNJ®. With precision engineering and top-tier materials, DNJ® Valve Lifters deliver exceptional performance and long-lasting durability.
