Product Details

The KYB Gas-a-Just KG54340 is a high-pressure monotube gas shock absorber designed to restore and enhance your vehicle's performance and handling characteristics. This premium shock absorber serves as a direct OE monotube replacement, offering superior responsiveness over traditional twin-tube designs.

Advanced Monotube Design Features:

  • Dual-chamber construction with separate hydraulic and gas chambers for optimized performance
  • Air-free hydraulic piston and valve area ensures immediate response and precise control
  • High-pressure nitrogen gas chamber with floating piston design maintains consistent damping
  • Monotube construction provides better heat dissipation compared to twin-tube shocks
  • Fade-free performance under demanding driving conditions
  • Improved handling and reduced body roll during cornering
  • Comfortable ride quality during normal driving with instant performance when needed

The Gas-a-Just monotube technology delivers the benefits of both comfort and control by separating the hydraulic fluid from the high-pressure nitrogen gas. This design prevents aeration and foaming of the hydraulic fluid, maintaining consistent damping force throughout the shock's stroke. The result is improved vehicle stability, enhanced steering response, and better overall control whether you're commuting or pushing your vehicle's limits.

The condenser works as expected. Came with a vacuum seal as well.

I was pleased with the delivery time. Faster than expected.

Would buy from again

I emailed to ask for information on the product but no one replied.

The photo showed with pads but when received no pads later I read the detail info on rotors which didn't mention pads then I new it was only rotors.

Fast!!!!!

Part was less than half the cost at local auto stores even with shipping. Thank you.

Nowhere seem to have HB3240 in stock wherever i looked. Glad i found you guys. Fingers crossed!

Good thus far, I will see after item is delivered.

Easy ordering and shipping to an alternate address, especially if you have an Amazon account. Item is exactly as desired and much less cost than other sites. So glad we discovered Autoplicity. We will use them again for future purchases.

I ordered arp head studs and it took 2 days to ship out but price was the best out for sure.

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
