Product Details

The Ksport GT Pro Damper System (CBM062-GT) delivers professional-grade suspension performance through an advanced inverted 55mm monotube shock body design. By positioning the gas/oil chamber farther away from the knuckle and braking system, heat transfer is significantly reduced while unsprung weight is minimized — resulting in sharper handling and improved steering responsiveness.

Key Features:

  • Inverted 55mm Monotube Shock Bodies: The inverted design lowers unsprung weight and improves heat dissipation compared to conventional twin-tube designs. The monotube configuration separates oil and gas within the cylinder, dramatically reducing aeration and cavitation for a consistently smooth ride.
  • 36-Way Adjustable Damping: Fine-tune compression and rebound simultaneously with 36 distinct damping settings, allowing precise calibration for everything from daily commuting to aggressive track use.
  • Metal Pillowball Top Mounts: Front and rear pillowball top mounts (application-dependent) preserve OEM suspension geometry while delivering a more direct, connected feel for improved driver feedback. Select applications include built-in camber adjustability directly at the coilover — eliminating the need for a separate camber kit.
  • Adjustable Lower Mount & Spring Perch: Ride height is adjusted via the lower mount on most applications, preserving full suspension travel — unlike designs that sacrifice travel during height adjustment.
  • 6061 Billet Aluminum Construction: Mounts and major components are CNC-machined from 6061 billet aluminum for an ideal balance of strength, light weight, and corrosion resistance.
  • Zinc Electroplated Steel Shock Body: The steel shock body receives a zinc electroplating treatment for long-term rust and corrosion resistance.
  • Matched Valving & Springs: Each set is valved specifically to match the installed springs, ensuring optimized ride quality and long-term reliability right out of the box.

The monotube design outperforms twin-tube alternatives by dissipating heat more efficiently, enabling finer damping adjustments, and maintaining performance consistency under demanding driving conditions. The result is a coilover system that performs equally well on the street and the track.

Price on shipping was good

I only gave them a 3 star raring on their shipping because I went on their site on Tuesday and the order said it had not been shipped. On Wednesday I received my shipment. The left hand needs to figure out what the right hand is doing. Other than that, GREAT

I have been looking for a Thule bike rack and finally found it here for the cheapest price and it was in stock!! Fast shipping, great customer service(PH), and lowest price on the web. My order was shipped on the same day it was placed, my order # is 5674. I am set to receive my order tomorrow. Couldn't be more pleased! Thx

Greatest web site i have been to in a long time. Great products, affordable prices, and my item wa shipped fast. I would highly recommend and i will be back.

Autoplicity was the least expensive and had great response time in regards to shipping. I will use Autoplicity next time I am needing automotive parts. Thanks
