8410 & 8411. A TOP QUALITY standard chain damper blade and spring for the upper timing chain damping on the classic Jaguar XK120 and early XK140s engine blocks C4810. Manufactured for us by specialist spring-makers from the correct spring steel, so will not wear and snap, like other cheaper versions! Our part number for this item is 8410 and 8411 (blade and spring). Jaguar original part number C4100 and C4101. (C2156 supercession)

NOTE : As an alternative to this crude system, we also offer the Jaguar Racing upgrade, our very popular 'C-Type' hydraulic conversion kit. Our part number : SE822

SE822 replaces the blade and spring mechanism with the oil feed from oil spray bar outlet that is re-routed through a brass block, which then mounts an XK150 hydraulic chain damper setup for a long and rattle free life!
