Description

Ksport GT Pro Damper System provides the ultimate in suspension technology featuring its inverted monotube design, 36 levels of adjustable damping, adjustable spring perch, adjustable body and pillow-ball mounts. With the gas/oil chamber farther away from the knuckle and braking system reducing heat transfer. This design also reduces under-sprung weight, which improves handling and responsiveness.

36 levels of damping adjustment allow you to fine tune the ride to your handling and comfort needs. The damping adjusts compression and rebound simultaneously for ease of adjustment. Pillow ball top mounts in the front and rear on some applications allow you to maintain vehicle manufacturer suspension geometry design. The pillow ball top mounts also allow you a more direct feel for solid driver response. Camber adjustability is included on pillow ball top mounts that allow it for the ability to adjust camber from the actual coilover, instead of a separate camber kit.

Most applications utilize an adjustable lower mount, which means you adjust height without losing suspension travel like some other coilover designs do. With the mounts and most pieces of the coilover being designed for 6061 billet aluminum the kit is lightweight, durable, and rust resistant. The steel shock body is electroplated with zinc to resist rust and the elements. The valving of each set is matched to the springs installed for unmatched ride quality and reliability.

The Ksport system uses a Monotube design in which the oil and gas are separated within the cylinder. When compared to twin tube designs the Monotube dissipates heat better, allows finer damping adjustments, and requires more expensive design process. Aeration and cavitation are a lot less common in a Monotube design, which results in a better ride.

Inverted steel shock absorber for increased response and heat build up

The main Focusof our GT Pro damper systems is that they feature an inverted front design. Inverted shocks move the gas/oil chamber farther away from the knuckle and braking system reducing heat transfer. This design also reduces unsprung weight which helps improve handling and responsiveness. NOTE: on inverted shocks the damping knob is at the bottom of the shock. Each kit is supplied with a flexible damping adjustment knob for easier access.

Large 55mm shock bodies

GT Pro coilovers use large 55mm shock bodies. This allows for added oil capacity for increased cooling efficiency. They also perform better under stress situations which make them perfect for track events.

Heavy duty steel lower mounts

GT Pro coilovers feature increased strength steel lower mounts. Also standard are brake line and sensor brackets. Steel is slightly heavier than aluminum but offers much stronger protection under stress situations.

All metal pillowball for added strength and responsiveness

A step up from their Kontrol Pro coilovers, the heavy duty all steel pillowball adds more strength and better steering response. You may experience slightly more noise with this type of pillowball, which is completely normal when compared to oem suspension where noise is reduced by using rubber parts. Their patented new top nut and bearing system helps combat noise while turning at slow speeds unlike other coilovers on the market.

36 way adjustable damping

All Ksport coilovers offer 36 levels of damping which allow you the ability to perfectly dial in your coilover system. 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

Their 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 have height adjustment via the spring perch and the lower mount of the shock. 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 their 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.

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 of their coilovers are electroplated with zinc. We also include an anti-rust paste packet with our systems 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 company?s designs.

12 month limited warranty

GT Pro coilovers come standard with an 12 month warranty which covers manufacturer defects.
