Product Details

The KYB Gas-a-Just KG4739 is a high-pressure monotube shock absorber designed to restore your vehicle's original handling capabilities and provide enhanced performance on demand. This monotube design offers superior heat dissipation and more consistent damping compared to traditional twin-tube shocks, making it an excellent choice for drivers seeking improved responsiveness and control.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area ensures precise responsiveness and fade-free control
  • High-pressure nitrogen gas chamber with floating piston provides instant performance response
  • Superior heat dissipation prevents shock fade during demanding driving conditions
  • Maintains comfortable ride quality during normal driving while delivering enhanced control when needed
  • Direct OE replacement fitment for easy installation
  • KYB quality engineering for long-lasting durability and reliability

The Gas-a-Just monotube construction keeps the hydraulic fluid and nitrogen gas separated by a free-floating piston, eliminating air contamination and maintaining consistent damping performance. This design provides firm, controlled handling without sacrificing everyday ride comfort, making it ideal for trucks, SUVs, and performance vehicles that demand more from their suspension system.

A very satisfactory experience. The price I paid was the lowest I found on the internet for this product. Ordering was easy, and without hassle. My order was shipped promptly and arrived sooner than I expected. Order date to receipt was only 6 days

Ordered EBC brake rotors on Tuesday afternoon and received notification on Thursday morning that they have already been shipped. Fast order processing and a low price, what more could I ask for? When I need to do the front brakes, I will be coming here first.

yes happy after a good customer serice helped with a price adjustment to my order. they did have good prices on most things, but it took some work to find the lowest price, so you do need to be a smart shopper.

Excellent service and communication.

Ordered a Thule Bike Rack from Autoplicity and was greatly pleased with the price. It was the best on the internet. There was an issue with the shipment of the item and some confusion but this was resolved in a professional manner by a customer service manager. Overall, I'm pleased I got a deal.
