Coilover Systems


1. How do I adjust the damping on my Ksport coilovers?

All Ksport coilovers are 36 levels damping adjustable. For inverted shocks (GT Pro, certain Rally and Slide Kontrol applications), the damping is adjusted from the bottom. On non-inverted shocks (Kontrol Pro, Version RR, Circuit Pro, and certain Rally and Slide Kontrol applications) damping adjustments are made from the top of the coilover. Simply insert your damping knob, and turn. Each click is 1 step of the 36-way adjustability. For a baseline setting, turn the knob until it stops and then turn it back 18 clicks. This is your baseline setting. Use this as a starting point when adjusting your coilovers.

2. Will I lose shock travel when lowering my vehicle?

Ksport coilovers have an adjustable lower mount which allows the shocks to maintain full travel when lowering the vehicle. This is an advantage compared to other coilover designs that rely on using the spring to adjust ride height, which in turn, loses shock travel. When lowering the vehicle with the spring, it can cause premature failure of the shock and horrible ride quality.

3. My coilovers are making a pinging sound, why?

For those that have coilovers and are experiencing a pinging sound from their coilovers at slow speeds, while turning, while entering or exiting an incline such as a driveway there may be a metal pinging sound. This is what we call coil-bind and there are a couple ways to fix this issue. The first thing to check is the metal washer on the top and bottom of your spring (McPherson suspension type only), make sure the washer is free from dirt debris and use either WD-40 or lithium grease to lubricate it. If you still encounter a noise then you will want to check your spring preload. When the vehicle is on jack stands or on a lift, the spring should be snug against the spring perch and still be able to rotate left or right. The spring should not move up or down, if it does, tighten the spring perch to where the spring is snug. Spring preload is always set from our factory and should not be adjusted. Always remember do NOT adjust the ride height of the vehicle using the spring perch.

4. I hear a clunking sound coming from my coilovers, why?

Coilover systems in vehicles with McPherson suspension type have metal pillowball bearing upper mounts. Because there is metal on metal contact, sometimes you may experience noise. You would not hear this in your OEM suspension due to the fact that OEM suspension masks many noises with the use of rubber parts. If you have continued abnormally loud noises that you believe are coming from your coilovers, double check the torque on the top lock nut. This nut should be torqued to 40 ft-lbs. We do not recommend using pneumatic impact guns on the top nut as they have a tendency to very easily over torque. Use a torque wrench to make sure the hardware is properly tightened. If you still have noise, inspect the other suspension components on the vehicle as there could be something else unrelated to your coilovers causing the noise.

5. My coilovers do not have camber plates, why?

Only McPherson style suspension offers the ability to have camber plates in the front. If your car has wishbone suspension or multilink then you would adjust camber using eccentric bolts or adjustable arms.

6. How do I adjust my ride height?

Never adjust ride height using the spring perch. Our systems are designed to adjust ride height via the lower mount. Make sure the spring perch (B) and locking collar (C) are locked by using the spanner wrenches and turning them in opposite directions so they lock against each other. Next, loosen the lower locking collar (D) and spin it up the amount you want to lower the car (for example, if you want to lower your car 2″ then spin the collar up 2″). Now use the spanner wrench on the spring perch (B) and begin turning the perch clockwise. This will thread the entire shock assembly further down into the lower mount (E). Once you adjustments are completed, tighten the lower locking collar (D) in place against the lower mount. If you need to raise your car, follow the same steps except turn the shock assembly counterclockwise. See diagram below. 

For vehicles without and adjustable lower mount, use the spring perch to adjust ride height. By lowering the locking collar (C ) and spring perch (B) the suspension is allowed to compress. This will result in a lower ride height. After your adjustments are made, tighten the spring perch and locking collar together using the spanner wrenches. Most vehicles without and adjustable lower mount will make use of Helper Springs. See diagram below. 

For vehicles with a separate spring and shock, part (A) is used to adjust ride height. After desired ride height is reached with the spring, it is extremely important to adjust the length of the shock by adjusting (B) to your desired position. The last step is to install the wheels and put the car on the ground and move the vehicle 20-30 feet to allow the suspension to settle. Then adjust (B) to let (C) compress 1/3 of the way into the strut and leave 2/3 of the shock shaft outside the strut; then tighten the locking collar against the lower mount. Use of a zip tie or black marker may be useful in judging how to make sure 1/3 of the shock is in the strut. Failure to set the shock stroke correctly will result in damage to the shock and void the warranty. For safety reasons, at least 30mm of the lower mount should be threaded onto the shock. See diagram below. 

7. Can my coilovers be rebuilt and how much does it cost?

Our coilovers are rebuildable, however it takes far less time to replace the entire shock unit with a brand new one instead of you taking them out of your vehicle, sending them to us and we disassemble them and replace any necessary parts. You are more than welcome to send in your coilovers so we can inspect them or you can use our extensive online store to source out which parts you may need if you are the DIY'er and want to minimize downtime and swap out the parts yourself. Brand new replacement shocks can be purchased starting at $135 and up + shipping.

8. What maintenance is needed / how do I care for my coilovers?

We recommend you periodically inspect your coilovers, especially in climates where you have lots of rain or snow. Dirt and debris can accumulate over time and can cause problems later down the road when you want to adjust ride height. Cleaning agents such as Simple Green and even wheel & tire cleaner are excellent choices, along with a soft wire brush or even your sister's toothbrush. You don't go a year or two without washing your car do you? Yeah that's what we thought. Keep your coilovers clean!

9. Where can I purchase replacement parts for my coilovers?

We offer a comprehensive list of replacement parts for your Ksport Suspension. Please visit the Replacement Parts section of the Ksport Store where we've accumulated countless photos to make it easier to find what you need fast. Order online and we will ship the parts right to your door.

Identify My Coilover

When ordering replacement parts for your Kontrol Pro coilovers there is some specific information you may be asked to make sure we get you the correct parts you need. The information below can help you have that information ready before you contact us.  For vehicles that use McPherson type suspension there was a production change in the beginning of 2009, therefore the information below can help you determine what size shock body you have.  This mainly only applies to front shocks (very few rear shocks).  If you're unsure if your vehicle has McPherson type suspension then please call us and we can help you 480-829-8100.
If your shock body is Chrome and it is a Kontrol Pro system, your shock diameter is 50mm. See image A.

Image A 

If your McPherson type shock body is Black and was purchased new prior to 2009, it can be either 50mm OR 52mm depending on its production date. Refer to image C. If your coilovers were purchased new mid 2009 or newer then your McPherson type shock is more than likely 52mm.

To determine what size the shock body is, you will need to measure it with a digital caliper as shown below.
