Key Features

  • 19mm Diameter Steel Tubing: Provides firm resistance to chassis lean, sharpening turn-in and stability on twisty roads.
  • High-Strength Chromium-Manganese Alloy: Cold-formed construction resists flex and fatigue for long-term durability under hard use.
  • Greasable Polyurethane Bushings: Deliver smooth articulation and quiet operation, eliminating squeaks common in dry bushings.
  • Complete Hardware Kit: Zinc-plated brackets, end links and fittings ensure rust-free, hassle-free mounting.
  • CAD-Engineered Design: Matches Honda geometry perfectly for even weight distribution and neutral handling.

Product Notes

  • Excludes Hybrid models; confirm submodel before purchase.
  • Pair with Eibach front anti-roll kit for full Pro-Alignment benefits.
  • Standard ground shipping; secure boxing prevents damage.

Installation Notes

  • Professional installation recommended.
  • Bolt-on design takes 1-2 hours with jack, stands and basic wrenches; follow torque specs of 40-50 ft-lbs.
  • Compatible with stock shocks/struts and aftermarket end links; no welding or subframe mods needed.
