2006–2009 Honda Ridgeline Bolt Sizes & Torque Specs

Lug nut torque is not verified for this summary. Review the cited evidence and exact hardware application before installation.

This page distinguishes source-backed fields, unresolved conflicts and unverified legacy records for the 2009 Honda Ridgeline. Match the exact hardware and manual conditions before maintenance. A source for one field does not verify the other specifications.

These specifications also apply to the 2006, 2007 and 2008 model years — identical specs on file for each year.

Honda and Acura platforms often reuse lug-thread conventions across related models, but the socket and torque must come from this vehicle's own record. Do not substitute a common import socket size for a measured lug nut.

Common fastener categories on the 2009 Honda Ridgeline

Wheel / lug nut torque and thread spec (covered above)
Brake caliper bracket, mounting, and slide/guide-pin bolts are different fasteners. Confirm the exact axle, application and service-manual specification before reassembly.
Engine oil drain plug torque and tool size when this vehicle has a verified drain-plug record
Transmission pan, valve cover, and intake manifold bolts where the database has exact records
Suspension control arm, sway bar, tie rod end and ball joint torque
Spark plug torque only when a vehicle-specific spark-plug row is available
Differential cover bolts (RWD/4WD only) and transfer case fasteners

Repair guidance for this model year

For 2009 model-year work: Always use a calibrated torque wrench for safety-critical fasteners, and replace lock washers and crush washers on every reassembly.

Tools you will need

Metric socket set (8mm-22mm), 6-point impact-rated
Calibrated torque wrench (10-150 ft-lbs covers most automotive jobs; add a 0-250 ft-lbs wrench for truck lug nuts)
Breaker bar (24" minimum) for initial loosening
Penetrating oil (PB Blaster or Kroil) for any fastener over 5 years old
Replacement washers, threadlocker, anti-seize, or dry-thread preparation only when the exact service procedure specifies them

Frequently asked questions

What is the lug nut torque on a 2009 Honda Ridgeline?

Specification not verified for this lug nut summary. Do not substitute another model year's value.

What socket size do I need for the 2009 Honda Ridgeline lug nuts?

Confirm the socket against the actual lug nut; no size is assumed here.

Are the 2009 Honda Ridgeline fasteners metric or SAE?

Metric is the standard for this vehicle. Most fasteners on this vehicle are metric (M6, M8, M10, M12, M14). Bring a full metric set; SAE substitutes can round the head. Bolt-head markings are the fastest way to confirm grade and material at the bench.

Other Honda Ridgeline years

Same model, different model year — fastener spec may change. Always confirm against the year for your VIN.
