Cusco 377 475 A Type I Front Lower Arm Bar 1997-2001 Honda CR-V

Brace the Front Lower Arms of Your 1997-2001 Honda CR-V for Sharper Steering and Better Traction

The Cusco 377 475 A is a Type I (Version 1) front lower arm bar for the 1997-2001 Honda CR-V RD1. Where a strut tower bar works at the top of the suspension, the 377 475 A works at the bottom, connecting the left and right front lower arm mounting points to reduce lateral flex in the front subframe. According to Cusco, this two-point connection prevents body flex that builds up under hard cornering and acceleration, improving steering rigidity, response, and traction. The bar is made from lightweight aluminum tubing and coated in Cusco's signature blue finish. It installs using a combination of included hardware and reused factory bolts, with no permanent modification to the vehicle required.

Key Features

• Type I two-point design connects the left and right front lower arm mounting points to resist subframe flex

• Reduces body flex under cornering loads to improve steering rigidity, response, and traction per Cusco's own documentation
• Bolt-on installation using included hardware and factory bolts, no permanent modification required
• Can be used in conjunction with a Cusco Type II lower arm bar (Type I and Type II are designed to complement each other)
• Made in Japan by Cusco

Frequently Asked Questions

The Cusco 377 475 A is a Type I front lower arm bar for the 1997-2001 Honda CR-V RD1. It connects the left and right front lower arm mounting points using a two-point aluminum brace to reduce subframe flex, improve steering rigidity, and sharpen traction response under cornering and acceleration loads.

The front lower arm bar acts as a brace at the bottom of the suspension, connecting the inboard mounting points of the left and right front lower arms. This stiffens the front subframe structure, reducing the lateral flex that occurs under hard cornering or acceleration. The result, as documented by Cusco, is improved steering rigidity, response, and traction. It is the lower-chassis equivalent of a strut tower bar that works at the top of the suspension.

The Type I (Version 1) uses a simple two-point connection at the left and right lower arm mounts. The Type II (Version 2) adds additional connection points to the subframe, providing greater overall rigidity. Cusco designs both versions to work together: the Type I and Type II can be installed at the same time for maximum front subframe bracing on the 1997-2001 Honda CR-V RD1.

Yes. This bar is designed for the 1997-2001 Honda CR-V RD1 platform across LX, EX, and SE trims in both front-wheel drive and real-time 4WD configurations. The front lower arm mounting point layout is the same across drivetrain variants on this platform.

Installation does not require any cutting or welding to the vehicle itself. However, Cusco notes in their installation instructions that the plastic factory undercover may need a small section trimmed if the bar makes contact with it after installation. The modification is to the removable plastic undercover, not to the chassis or subframe.

Yes. This bar mounts to the lower arm subframe mounting points, not to the strut or spring assembly itself. It is compatible with suspension upgrades including coilovers and lowering springs as long as the aftermarket setup retains the factory lower arm mounting point configuration on the 1997-2001 Honda CR-V RD1.

A lower arm bar does not alter spring rates, damping, or ride height. It only reduces structural flex in the front subframe. The effect on ride comfort is minimal to none on a street-driven vehicle. Some owners report a slight improvement in steering feel, while others with already-stiffened suspension setups notice little difference, with results varying based on overall build stiffness.

Cusco products are backed by a manufacturer warranty against defects in materials and workmanship. Direct warranty inquiries to Cusco or the authorized distributor from whom the product was purchased. Retain your proof of purchase for any warranty claims.

Installation Instructions

1. Safely lift and support the vehicle using jack stands rated for your vehicle's weight. Do not work under a vehicle supported only by a floor jack.
2. Remove the plastic factory undercover if equipped. Set the undercover fasteners aside for reinstallation.
3. Locate the front lower arm mounting points on both the driver and passenger sides of the subframe.
4. Remove the three factory bolts at the lower arm mounting locations as indicated in Cusco's installation guide. Two of these factory bolts will be reused in the next step.
5. Position the bar against the mounting points on both sides of the subframe.
6. Secure the bar using the two reused factory bolts and the included M8 x 15 flange bolt and M8 flange nut. Thread all fasteners by hand before final tightening.
7. Torque all fasteners to the appropriate specification. Reinstall the factory undercover. If the bar contacts the undercover, carefully trim only the shaded area shown in the installation guide to provide clearance.
8. Periodically inspect and retorque all nuts and bolts after vehicle operation.
