Product details
Ksport Kontrol Pro Fully Adjustable Coilover Kits provide the ultimate in suspension technology for your vehicle, both on the street or at the track. 36 levels of damping adjustment allow fine tuning of the damper to suit both handling and comfort needs. The damping adjustment alters compression and rebound simultaneously, for more effective and user-friendly setup changes.
Pillowball Top Mounts
Pillow ball top mounts in the front and rear on some applications allow the vehicle to install and setup to OEM specifications. Ksport's patented upper pillow ball mount offers the same level of adjustability and performance but allows for compliance that is often required from high-demand strut applications.
On applicable models, the pillowball upper mounts offer camber adjustment, saving the need for a special, separate camber kit. For enthusiasts seeking the ultimate in adjustability, Ksport's advanced upper pillow ball mount is available on some applications, giving the option for separate camber and caster adjustment.
Adjustable Lower Mounts
Most applications utilize an adjustable lower mount, which means height adjustability without losing suspension travel - a problem found in many coilover systems available today. Since mounts and most pieces in the coilover system are designed from 6061 billet aluminum, the components are lightweight, durable, and rust resistant.
Protection Against Corrosion
Steel shock bodies are electroplated with zinc to resist rust and protect from the elements. The shock or strut valving for each piece is matched accordingly to the spring rate, giving superior ride quality and reliability.
Superior Ride Quality & Reliability
The Ksport system uses a Monotube design in which the oil and gas are separated within the cylinder. When compared to twin tube construction, the Monotube design dissipates heat faster and more evenly, allows finer damping adjustments, and requires more expensive design process. Aeration and cavitation issues are a lot less common in a Monotube design, which results in a more consistent ride quality.
The Ksport Kontrol Pro Coilover system has been designed with professional road racing in mind, offering extremely high value and performance for any application.
Features:
36-Way Adjustable Damping
All Ksport coilovers offer 36 levels of damping which allow you the ability to perfectly dial in your coilover kit. Set damping to full soft for a nice comfortable cruising setting for normal driving.
Collars and Upper Mounts Made from 6061 Aluminum with T6 for Increased Hardness
Our spring perches, locking collars, top mounts and some lower mounts are made from high quality 6061 aluminum. Benefits include excellent strength and aluminum helps reduce weight.
Adjustable Spring Perch for Height Adjustment
Some vehicles have a separate rear shock and spring. In the coilover industry we call this a “hi-low kit". In this case you will adjust ride height via the spring. Adjustable lower mounts on the rear shock aid in setting the correct shock stroke. Vehicles with this type of set up can still go as low or lower than true coilovers.
Adjustable Lower Mount Allowing Maximum Suspension Travel
Most of our coilovers feature the ability to adjust your ride height without affecting the shock and spring travel. This way you can set your desired ride height without having to worry about bottoming out the shock.
Camber Adjustment on Many Models
Many of our applications that have pillowball upper mounts also have camber adjustability. This is extremely helpful when you need to dial in your camber for vehicle alignment purposes. This also eliminates the need for a separate camber kit. NOTE: Camber adjustment is not available on all models with pillowball upper mounts.
Pillowball Top Mount for Increased Steering Feel
Many of our applications for vehicles with McPherson type suspension will have pillowball upper mounts. Our patented new bearing design helps combat noise while turning unlike many other coilovers on the market. Steering feel and response is improved with pillowball upper mounts.
Monotube High Pressure Design Reduces Oil Leakage
All of our coilovers use Monotube shocks which dissipate heat better, allows finer damping adjustment and requires a more expensive design process compared to twin tube shocks.
Electroplated Body for Added Protection from Corrosion and Rust
To help prevent corrosion and rust from the elements of nature, all our coilovers are electroplated with zinc. We also include an anti-rust paste packet with our kits that can be applied to certain key areas of the coilover for added protection.
Dust Boot to Protect Damper Seal
Dust boots are standard on all coilovers. We also integrate the bump stop inside the dust boot. This is more efficient and is less likely to crumble to pieces and deteriorate like other designs.
12 Month Limited Warranty
Kontrol Pro coilovers come standard with a 12-month warranty which covers manufacturer defects.
Supported features
Every KSport coilover offers 36 levels of damping adjustment. Set full soft for comfortable daily driving, or firm up the compression and rebound for the track.
Applications with a pillowball upper mount often include camber adjustment — useful for dialing in alignment after lowering, and it removes the need for a separate camber kit.
Applications for MacPherson-strut suspension typically use a pillowball upper mount. The bearing design resists the noise common to other coilovers, and steering feel and response improve.
Most Kontrol Pro applications adjust ride height independently of shock and spring travel, so you can set your stance without risking bottoming out the shock.
Oil and gas stay separated within the cylinder. Compared with twin-tube construction, a monotube design dissipates heat faster and more evenly, allows finer damping adjustment, and resists aeration and cavitation.
Mounts, collars, and spring perches are machined from 6061-T6 billet aluminum for a lightweight, durable, corrosion-resistant build. Steel shock bodies are zinc-plated for added protection from corrosion.
A dust boot is standard on every Kontrol Pro coilover to protect the damper seal, with the bump stop integrated inside it — more efficient, and less prone to crumbling than a separate bump stop.

Installation
Set ride height with the adjustable lower mount where the application has one; use the spring perch only where the application-specific layout has no adjustable lower mount. Lock every collar with both spanner wrenches. Start damping 18 clicks counterclockwise from full stiff and adjust from there. Professional setup and alignment are required after installation; on MacPherson fronts, establish baseline camber at the elongated lower-mount hole before fine adjustment at the upper plate.
