H&R Sport Springs and Damper Selection

Review the H&R W126 Sport spring kit listed for 1981–1991 SEC/SEL applications with self-leveling suspension and non-diesel coverage.

Match the intended axle, hub centering, wheel interface, fasteners and measured clearance. Review Eibach Pro-Spacers independently against their complete manufacturer application and installation requirements.

Ignition, Filtration and Lamp Maintenance

Choose NGK plugs by the engine’s required specification and exact part number. Match the K&N air filter to full engine coverage and the installed airbox. For Hella bulbs, check lamp position, base, electrical requirements and quantity. Select brake hoses, calipers and pads by exact application, axle position, dimensions and connections.
