Product Details

The KYB Gas-a-Just KG5787A is a high-performance monotube gas shock absorber engineered to restore and enhance your vehicle's ride quality and handling characteristics. Designed as a direct OE monotube replacement, this shock provides superior performance over traditional twin-tube designs.

Advanced Monotube Technology:

  • Dual-chamber design with separate hydraulic and gas chambers for optimal performance
  • Air-free hydraulic piston and valve area ensures consistent responsiveness and precise control
  • High-pressure nitrogen gas chamber with floating piston separates oil from gas to prevent aeration
  • Monotube construction allows for better heat dissipation compared to twin-tube shocks
  • Larger piston diameter provides increased surface area for improved damping capacity

Performance Benefits:

  • Delivers a comfortable ride during normal driving conditions
  • Provides instant performance enhancement on demand during aggressive driving
  • Maintains consistent damping performance even under extreme conditions
  • Restores original vehicle handling and control capabilities
  • Reduces body roll, brake dive, and acceleration squat

The Gas-a-Just monotube design is ideal for drivers seeking improved handling and performance without sacrificing everyday ride comfort. The nitrogen gas charge and floating piston technology ensure fade-free performance and longer service life.

Fine

The part was advertised as Goodyear but Goodyear sold or divested its interest in Gatorback belts to Continental. The belt I received was a Continental Elite Poly-V Belt which is the same as the Goodyear Gatorback belt. Autoplicity needs to update its website. I contacted Autoplicity after placing the order when I found on another website that Goodyear no longer makes Gatorback and asked what belt I was going to be sent. Justine O, a Senior Production Specialist directed me to the generic Goodyear website which had nothing about Gatorback belts because they no longer make Gatorback belts... thank you Justine O, Senior Production Specialist for absolutely nothing! Bottom line, Autoplicity may, or may not have what you want... but one thing is for certain, their customer service is as useless as every other customer service you have ever dealt with!!!

Had what I needed for a great price and a friendly website.

They where to big to fit but everything else was good on how fast was delivered n price but just not right thanks

great product and service

Smooth !!!!

If all goes well then ill shop here again

everything was great just fix your PayPal button

Easy to Navigate. They have everything. Great Selection. Very good price and sometimes the best.

So far, so good. Now for the installation. Will let all know how well everything performs.

Autoplicity has the cheapest prices around and fast shipping. I will do business with them again in the future.

Excellent price, and in stock!! Received fast, not the first, will not be the last time I look to Autoplicity for auto parts.

Item arrived promptly (4 days after order), price was good and item was as described.
