The Eibach Pro-Kit 4044.140 is a set of four progressive-rate lowering springs, front and rear, for the 3.0-liter V6 Honda Accord. The listing is a set of 4 springs and is shown for 2003-2007 Honda Accord 3.0L models, excluding Hybrid. The manufacturer describes the Pro-Kit line as delivering high performance handling and improved appearance, without compromising ride quality. Owners on user forums say the kit gives a fairly even, mild drop that looks stock, which makes it a sensible step up from worn factory springs without the harsh ride of a stiff sport spring or the cost and upkeep of coilovers.
Fitment is the first thing to confirm. Eibach's listing covers the 3.0L V6 but excludes the Hybrid, so check your year and trim before ordering. Owners on user forums report that the kit works with factory struts and that a camber kit was not needed on their V6 cars, though an alignment check after installation is still wise. For the install, owners describe a job of roughly 3.5 to 6 hours. A lift or jack with stands is the usual setup, and a torque wrench and spring compressors are needed. Greasing the rear mounting bolts helps them stay in the socket while you reach into the rear deck, and a helper is handy for starting the front strut nuts.
No. The manufacturer's application listing for part 4044.140 excludes the Hybrid and covers 3.0L models only.
Owners on user forums report that the springs ride well on factory dampers, but some warn that worn stock shocks will wear faster under lowered springs. Replacing old dampers at the same time is a common choice.
Owners on user forums report running this kit on the V6 without a camber kit. Alignment should still be checked after installation, and the manufacturer's install sheet is the best reference for specific procedures.
This is a moderate-difficulty job for a home mechanic with a lift or jack stands, a torque wrench, and spring compressors. Owners on user forums report it is manageable in a single weekend afternoon, with the rear springs usually easier than the fronts. The rear top strut nuts sit behind a plastic access panel, and popping the plastic rivets gives room to guide the socket and start the nuts. Some sedan owners have had to remove the rear seat and shelf, so check your body style before you start. Plan for an alignment afterward.
