KYB Accessories

Gas-a-Just™ Series Shocks and Struts by KYB®. Go with Gas-a-Just shocks and struts and experience greater stability, handling, and control over twin-tube designs. Whether your vehicle is originally equipped with a monotube or twin-tube design shock, the Gas-a-Just monotube shock is the perfect choice to upgrade or restore suspension performance.

KYB TechnologyKYB ProductsKYB About

Features:

  • Replacement for an OE monotube shock to restore/keep the vehicle's original performance characteristics
  • Ideal as an upgrade from an OE twin-tube for quicker, more responsive handling and control
  • The more responsive monotube design automatically adjusts to driving conditions
  • Cushions the ride
  • Increases steering responsiveness by as much as 30%
  • No aeration or performance fade
  • Recommend replacement in pairs

A lot of us use our vehicle for more than just daily commuting. Many of us pull trailers or transport heavy items, so we need more ride control and performance than usual. KYB has a sound solution for all of these driving needs – the Gas-a-Just monotube shock absorber! The name of the shock stands for gas automatic adjust. The Gas-a-Just will outperform the average twin-tube design; it never experiences shock fade and has a unique ability to automatically add performance when it's needed. The Gas-a-Just has two possible purposes. For those vehicles that are already equipped with a high performance monotube design, the Gas-a-Just will serve as a direct replacement to restore the vehicle's originally designed performance. But the Gas-a-Just can also be a great performance upgrade for the vehicles that are equipped with standard twin-tube shocks.

The Gas-a-Just features a larger single working cylinder, so the hydraulic fluid doesn't have to travel far. It's all kept in the upper cylinder so the valving can respond faster. There is also a Nitrogen gas high pressure chamber in the lower section (it is separated from the fluid area by a floating piston and seal). On light vehicle movement, the gas pressure cushions the ride, but when you need performance and there's more aggressive movement, the floating piston is pushed further into the gas chamber which increases gas pressure quickly and provides additional damping force. The Gas-a-Just is a great choice when you want something more than the original design. Whether you just want more responsive handling or perhaps you carry heavier loads than usually, or tow a trailer, the Gas-Just provides more stability and less body roll. So, install a pair of Gas-a-Just Shocks and Struts and experience a firmer ride and additional control.

KYB Corporation produces a variety of ride control, hydraulic, and electronic products for use as original equipment and replacement parts in automobiles, motorcycles, trucks, specialty vehicles, buses, aircraft, railroad cars, industrial applications, agricultural applications, and civil engineering projects. Our global headquarters are located in Tokyo, Japan.

WARRANTY PERIOD

KYB’s limited warranty is for the following periods for the following covered KYB products:

WHAT IS COVERED BY THIS WARRANTY?

This warranty covers defect in material and workmanship in the KYB product. KYB’s sole and exclusive obligation under this warranty is limited to the exchange/replacement of a defective KYB product in accordance with this limited warranty.

CAN THIS WARRANTY BE TRANSFERRED?

How to Make a warranty claim

  • Present the original retail proof of purchase (i.e. original sales receipt) listing a valid KYB part number for a covered product to the original place or point of purchase.
  • The product must be inspected to verify the product qualifies for a replacement/exchange under the terms of this warranty. The inspection and verification is provided free of charge to the original retail purchaser.
  • To have the product inspected and verified, the original retail purchaser must (a) return the alleged defective KYB product to the original place or point of purchase, and (b) submit a valid copy of the original dated retail proof of purchase listing a valid KYB part number for inspection and verification. If the original place or point of purchase no longer exists or for any other reason the original retailer purchaser is unable, despite good faith efforts, to return the product to the original place or point of purchase, the original retail purchaser must then return the alleged defective KYB product and proof of purchase to an authorized KYB product seller.
  • Warranty claims will only be honored for KYB products listed above and not otherwise excluded by this Limited Warranty.
  • If the provisions of this warranty are met and the product is determined to be defective and qualifies for replacement/exchange, the product will be replaced/exchanged with a new unit of the same or superseded KYB part number. In the case of a KYB product being superseded, the replacement part must be stated in the application section of the current KYB catalog.
  • Installation, removal and/or diagnostics are not included in this warranty.

(An example is where only one unit is defective and the consumer requests a pair be replaced. Since the KYB warranty only covers the defective unit, the claim for the worn but not defective unit will not be honored.) The cost of any diagnostics, removal of a defective KYB product and installation of a replacement KYB product is not included. The cost of transportation for the shipment of an alleged defective or replacement KYB product is not covered by this warranty.

KYB Shocks
As always this new set of KYB's delivered. Replaced almost new Monroe Sensatrac shocks that had too much body roll. KYB has a gas charged system with a much faster rebound rate then the Sensatrac. Excellent upgrade replacement shock. Buy with ease of mind, they work.

Very Good
I installed these on my 2000 Nissan Pathfinder and found them to be perfect, a complete 180 degrees from "stock" shocks. They give increased stability in turns, and also help keep the rear end from sagging so much when I have a trailer hitched up.
