Specifications

Setup and Installation

The BMR Suspension KM014-1R K-member is a direct replacement component designed to improve chassis rigidity and provide specific mounting options for turbo applications and Pinto steering racks. Follow these general steps for installation. Refer to your vehicle's service manual for specific torque values and additional procedures.

Required Tools and Equipment:

• Vehicle lift or jack stands
• Assorted wrenches and sockets
• Torque wrench
• Pry bars
• Fluid drain pans (for power steering fluid, if applicable)
• Penetrating oil
• Thread locker (medium strength)

Installation Steps:

1. Prepare Vehicle: Safely lift and support the vehicle. Disconnect the battery.
2. Remove Wheels and Suspension Components: Remove the front wheels. Disconnect and remove front suspension components attached to the factory K-member, including but not limited to:
   • Lower control arms
   • Struts/shocks
   • Sway bar
   • Steering rack (disconnect from steering shaft and tie rods)
   • Engine mounts (if applicable, though this K-member does not use them, the engine will need to be supported)
3. Support Engine: Securely support the engine from above using an engine hoist or engine support bar. Ensure the engine is stable and will not shift during K-member removal.
4. Disconnect Exhaust and Other Lines: Disconnect any exhaust components, brake lines, or other hoses/wiring that may interfere with K-member removal.
5. Remove Factory K-member: Carefully unbolt the factory K-member from the chassis. Note the orientation and location of all fasteners. Lower the K-member from the vehicle.
6. Inspect and Prepare: Inspect the chassis mounting points for any damage or corrosion. Clean the area thoroughly.
7. Install BMR Suspension KM014-1R K-member:

   Carefully position the new BMR Suspension K-member into place. Align the mounting holes with the chassis. Install the main K-member bolts, but do not fully tighten them yet. Ensure proper clearance for turbo components if applicable.

8. Install Steering Rack: Mount your Pinto-style steering rack to the designated mounting points on the new K-member. Use appropriate hardware and apply thread locker as recommended by the steering rack manufacturer.
9. Reinstall Suspension Components: Reattach all front suspension components (lower control arms, struts/shocks, sway bar) to the new K-member. Ensure all fasteners are installed correctly.
10. Connect Engine: If the engine was supported separately, carefully lower it and ensure it is properly seated. This K-member does not utilize traditional motor mounts, so ensure the engine is secured according to your specific engine mounting solution (e.g., solid mounts, mid-plate, etc.).
11. Reconnect Lines and Exhaust: Reconnect all brake lines, hoses, wiring, and exhaust components that were disconnected.
12. Final Torque: Once all components are in place and aligned, progressively tighten all K-member and suspension fasteners to the vehicle manufacturer's specified torque values. Double-check all connections.
13. Final Checks: Reinstall wheels and lower the vehicle. Check for proper steering and suspension operation. Bleed brakes if any lines were opened. Perform a wheel alignment.

It is highly recommended to have a professional alignment performed after K-member installation to ensure correct vehicle handling and tire wear.

Usage Considerations

After installing the BMR Suspension KM014-1R K-member, observe the following:

• Break-in Period: Drive cautiously for the first 50-100 miles after installation. This allows components to settle and helps identify any potential issues.
• Alignment: A professional wheel alignment is crucial after K-member replacement to ensure proper handling, tire wear, and steering response.
• Regular Inspection: Periodically inspect all K-member mounting bolts and associated suspension hardware for tightness. Check for any signs of wear or damage.
• Performance Characteristics: This K-member is designed for performance applications. Expect changes in vehicle dynamics, potentially including a firmer ride and more direct steering feel due to the reduced weight and increased rigidity.

Maintenance

The BMR Suspension KM014-1R K-member requires minimal maintenance. However, regular inspection is recommended to ensure longevity and safe operation:

• Visual Inspection: Annually, or more frequently if driven in harsh conditions, visually inspect the K-member for any signs of damage, cracks, or corrosion.
• Fastener Check: Every 6-12 months, or after any significant track use, re-check the torque on all K-member mounting bolts and associated suspension hardware.
• Cleaning: Clean the K-member as needed to remove dirt, salt, or other corrosive materials. Use mild soap and water, then rinse thoroughly.
• Paint Protection: The K-member features a durable powder-coated finish. If the finish is damaged, touch up with appropriate paint to prevent rust.

Troubleshooting

If you encounter issues after installing your BMR Suspension KM014-1R K-member, consider the following:

• Unusual Noises (Clunks, Squeaks):
  • Check all fasteners for proper torque. Loose bolts are a common cause of noise.
  • Inspect for any components making contact with the K-member or chassis that shouldn't be.
  • Verify that all suspension components are correctly installed and not binding.
• Poor Handling or Steering:
  • Ensure a professional wheel alignment has been performed.
  • Verify the steering rack is securely mounted and functioning correctly.
  • Check for any play in ball joints, tie rods, or other steering/suspension components.
• Engine Clearance Issues (for turbo applications):
  • Double-check engine placement and any custom engine mounts or mid-plates.
  • Ensure turbocharger downpipes and other components have adequate clearance from the K-member and chassis. Adjust as necessary.

If troubleshooting steps do not resolve the issue, contact BMR Suspension customer support for further assistance.
