Product Details

The Ksport GT Pro Coilover Kit (CSB040-GT) represents the pinnacle of Ksport's suspension engineering, building on the proven Kontrol Pro platform with meaningful upgrades for improved lifespan, durability, and on-track performance. At the heart of this system are large 55mm inverted shock bodies — significantly larger than the standard 20mm found on most coilovers — delivering greater oil capacity for superior cooling efficiency and more consistent damping performance under sustained use.

Key Features:

  • Inverted 55mm Monotube Shock Bodies: The inverted front design positions the gas/oil chamber farther from the knuckle and braking system, reducing heat transfer and allowing the kit to run cooler. This configuration also reduces unsprung weight, directly improving handling response and agility.
  • 36-Way Adjustable Damping: 36 discrete levels of damping adjustment allow precise tuning for everything from daily street driving to aggressive track use. Compression and rebound are adjusted simultaneously via a single knob, making setup changes fast and intuitive. On inverted shocks, the damping knob is located at the bottom of the shock; a flexible adjustment knob is included for easy access.
  • Metal Pillowball Top Mounts: Patented metal pillowball upper mounts are included on applicable applications, providing a more direct connection between the chassis and road surface for sharper steering feel and response. These mounts allow installation to OEM suspension geometry specifications while combating noise during cornering. On many applications, integrated camber adjustability eliminates the need for a separate camber kit.
  • Adjustable Lower Mount for Maximum Suspension Travel: Height adjustment is achieved via the adjustable lower mount rather than the spring perch, meaning ride height can be dialed in without sacrificing available shock and spring travel — a key advantage over many competing coilover designs.
  • Aerospace-Grade 6061-T6 Billet Aluminum Components: Mounts, collars, spring perches, and most major components are CNC-machined from 6061-T6 billet aluminum for an optimal combination of light weight, strength, and corrosion resistance.
  • Zinc-Electroplated Steel Shock Bodies: Steel shock bodies are electroplated with zinc to resist rust and protect against the elements. Kits also include an anti-rust paste packet for application to key coilover areas for added long-term protection.
  • Matched Valving and Spring Rates: Each kit's shock valving is precisely matched to its installed spring rates, delivering superior ride quality and reliability straight out of the box.
  • Monotube High-Pressure Design: The separated oil and gas chambers of the monotube design dissipate heat faster and more evenly than twin-tube alternatives, allow for finer damping adjustments, and significantly reduce the risk of aeration and cavitation for more consistent, fade-resistant performance.
  • Dust Boots with Integrated Bump Stops: Dust boots are standard on all units, with bump stops integrated inside the boot for a cleaner, more durable design that resists deterioration over time.
  • 12-Month Limited Warranty: Backed by a 12-month manufacturer's warranty covering defects in materials and workmanship.

The Ksport GT Pro coilover system is built to order and engineered for enthusiasts who demand track-ready performance without compromising street usability. Whether fine-tuning alignment geometry with the pillowball top mounts or dialing in damping for a specific driving style, the CSB040-GT delivers the adjustability and precision to do it all.

Thank you foryou fast service, and knowledge. I will definitely be shopping again for my automotive supply needs.

super service and best price on the net

First time buying at this wed site and was pretty simple

The product was great and delivery was fast. Autoplicity made the trans action very easy. The payment process was very secure and safy also. I will be ordering again from the company in the furture.<br><br>Tj Vandermarlierre

Ordering online from Autoplicity was quick and easy.<br>The item shipped quick and arrive a few days later via std ground shipping.<br>The quality and fit of the product (SUV cargo liner) was great, and it made a wonderful Christmas gift!<br>I will purchase from you again, thank you!

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

Thanks for the great service, best prices, and fast shipping!!!

Outstanding
