H&R part 51856-2 is a four-spring Sport lowering set for the four-door, six-cylinder 2008–2012 Honda Accord. It is a lower-cost first step toward a sharper stance and better handling than a full coilover conversion. The manufacturer's approval paperwork is a real point of difference from unbranded springs: its quality management system is certified to ISO 9001:2015 and meets the approval requirements of the Federal Motor Transport Authority for type and part approvals under German road traffic law. Buyers searching for H&R 51856-2 Accord V6 lowering springs or 2008-2012 Accord sport springs should confirm the application by VIN, because lowering amount and fitment notes vary by engine, trim, and model options.
Before ordering, check that your trim and engine match the four-door six-cylinder application, and ask the manufacturer if anything is unclear. The manufacturer publishes an installation and safety instruction sheet for its springs, so read it before you start the job. Owners on user forums also advise retorquing every fastener you disturbed to specification before booking an alignment, which keeps the new ride height from being undone by a misaligned front end. Pairing the set with factory or aftermarket dampers is a common owner question, so verify your damper setup with the manufacturer when you order.
This part number is designated for the four-door, six-cylinder 2008–2012 Accord. Lowering amount and fitment notes vary by engine, trim, and model options, so confirm the application with the manufacturer using your VIN before you order.
Owners on user forums recommend retorquing every fastener you loosened, then having the car aligned. Skipping the alignment is a common cause of uneven tire wear and steering complaints after a lowering job.
The manufacturer publishes an installation and safety instruction document for its springs on its customer service page. Read it before disassembly and follow its guidance during installation.
This is an intermediate job rather than a bolt-on. Front struts hold a compressed spring, and owners on user forums insist on a proper spring compressor before any spring is removed. Photograph how far each bolt and nut sits before disassembly so you can reproduce the original positions when reassembling. Use a torque wrench for all fasteners, and plan on a professional alignment afterward. Read the manufacturer's installation sheet first, because it is the authoritative reference for the procedure.
