How To Adjust Bc Coilovers Rear: Step-By-Step Guide

Adjusting your car’s suspension is crucial in attaining a personalized driving experience. Coilovers have become increasingly popular, especially for car enthusiasts who want to take their driving game to the next level. Bc coilovers remain one of the top brand choices due to their quality performance.

In this guide, we’ll be focusing on the rear part of your bc coilovers. By the end of this post, you will have a good understanding of how to adjust bc coilovers rear and significantly improve your driving experience.

Finding A Suitable Location

Finding a suitable location to work on your vehicle is crucial. Ensure that the surface is flat and solid, and there is enough room to maneuver around the vehicle. It is also advisable to work in a well-lit and adequately ventilated area.

Releasing The Locking Collars

Before disassembling the suspension, ensure that the locking collars are loose enough to enable free movement when adjusting the coilovers. It’s crucial to use a suitable tool, such as a spanner or a wrench, to loosen the collars.

Disassembling The Rear Suspension

To disassemble the suspension, you will need to remove the shocks and locking collars. Remember to mark the position of the locking collars before you remove them – this will help you return them to their original position. After removing the shocks and locking collars, you can proceed to reposition the coilovers.

Adjusting The Height

Adjusting the height of the coilovers is simple. You can either turn the bottom mount or the shock absorber body to raise or lower the ride height. Ensure that both sides are adjusted evenly to maintain balance. You can use a tape measure to ensure that the height is adjusted to your preferred measurements.

Reassembling The Rear Suspension

After adjusting the height, you can now reassemble the suspension by following the reverse process of dismantling it. Remember to torque to the manufacturer’s specifications and ensure everything is secure and in place.

What Is Dampening?

Dampening refers to a shock absorber’s ability to control the compression and rebound of the suspension system. Dampening can be adjusted to suit different driving styles and terrain.

Understanding The Adjustment Knob

Bc coilovers feature an adjustment knob that is responsible for dampening. The knob is turned clockwise to increase the dampening force and counterclockwise to decrease damping force.

Setting The Dampening

Before setting the dampening, it’s crucial to understand your driving style. If you prefer a stiffer ride, then a higher dampening force is suitable, while a softer ride requires less dampening. It is also essential to test the dampening to determine your preferred settings gradually.

Methods For Releasing Pressure

If you adjust the dampening force at one end of the coilover, you need to release pressure from the opposite end to maintain balance. There are different methods for releasing pressure, such as placing a jack under the tire or bouncing the vehicle.

How To Test Bc Coilovers Rear

After adjusting the rear coilovers to your preferred settings, the next step is to test them on a safe stretch of road. Test them by taking gradual turns and driving over bumps to see how they perform.

Signs Of Incorrect Adjustments

Finally, it’s important to know the signs of incorrect adjustments. Signs such as abnormal tire wear, bouncing, and body roll indicate a need for adjustment. If you notice any of these signs, re-examine your adjustments and readjust as needed.

Good luck!

Troubleshooting Common Bc Coilover Issues

Bc coilovers are popular for lowering your vehicle’s center of gravity, which provides better handling, steering response and a sleek, more aggressive style. However, adjusting the bc coilovers can be a little tricky, and you’ll need to keep an expert hand to ensure everything runs smoothly.

This blog post will explain how to fix some common issues when adjusting bc coilovers to achieve optimal performance.

Common Issues

Here are some common issues people face while trying to adjust their bc coilovers:

  • Coilover sleeve stuck
  • Loose damping adjuster
  • Rattling noise from the rear of the vehicle
  • Coilovers are not adjusting


Here are some simple solutions to these common issues:

  • Coilover sleeve stuck: if the sleeve is stuck, try spraying it with lubrication. The lubrication will help in loosening up the sleeve.
  • Loose damping adjuster: if your damping adjuster is loose, then it can be a serious issue. Check that the adjuster knob is well-seated and the rubber o-ring is not damaged. Too much dirt or debris in the threads might cause them to clog up and cause issues in adjustment.
  • Rattling noise from the rear of the vehicle: a rattling noise from the rear of the vehicle could mean there is an issue with the spring. Check if the spring is seated correctly, and if it has any damage or wear. Additionally, make sure that the coilover is mounted securely.
  • Coilovers are not adjusting: if the coilovers are not adjusting, the first thing to check is the locking system. Double-check that the locking rings are not too tight, making adjustments difficult. It could also be an issue with damaged threads or debris clogging them up.

Adjusting your bc coilover might be a little tricky, and several common issues might arise while you attempt it. However, with these solutions, you can quickly troubleshoot the most common problems and achieve optimal performance from your coilover.

Tips On Maintaining Your Bc Coilovers Rear

1. Inspect Regularly

Inspect your bc coilovers rear regularly to see if they have any leaks, damage, or signs of wear and tear. Look for any oil leaks around the shock body or mounting points, and make sure the adjuster knob turns smoothly.

2. Clean The Coilovers

Clean the coilovers regularly to prevent dirt and debris from building up. Use a mild soap and water solution and a soft brush to clean the shock body and adjuster knob. Rinse thoroughly and dry with a soft cloth. Do not use harsh chemicals or abrasive materials as they can damage the finish.

3. Lubricate The Adjuster Knob

Lubricate the adjuster knob regularly to keep it turning smoothly. Apply a small amount of silicone lubricant or wd-40 to the adjuster knob and turn it back and forth a few times to distribute the lubricant.

4. Check The Ride Height

Check the ride height regularly to make sure it hasn’t changed. Look for any signs of sagging or uneven height and adjust if necessary. A proper ride height ensures the coilovers are working correctly and your vehicle’s handling is optimized.

5. Check The Alignment

Check your vehicle’s alignment regularly, especially after adjusting the coilovers. A misaligned vehicle can cause uneven wear on tires and lead to poor handling. Make sure the camber, toe, and caster are correct.

6. Store Properly

If you are storing your vehicle for an extended period, make sure to store it properly. Lift the vehicle off the ground and support it with jack stands to prevent the coilovers from being in a compressed state for an extended period.

7. Seek Professional Assistance

If you’re not confident in performing any of the above maintenance procedures, seek professional assistance. A qualified mechanic or suspension specialist can inspect and maintain your coilovers properly. Don’t risk damaging your vehicle or yourself by attempting something you’re not comfortable doing.

By following these tips, you can ensure that your bc coilovers rear are always performing at their best. Regular maintenance and inspection will save you money in the long run by preventing expensive repairs and replacements.
