Truxxx 2018-2026 Hyundai Kona & 2019-2026 Kia Seltos Shock Shaft Extensions #304004

The Missing Link for Lifted Comfort: Restore Your Suspension Travel

If you’ve added a rear lift or leveling kit to your Hyundai Kona or Kia Seltos, you may have noticed a "clunk" or a harsh ride when going over speed bumps or potholes. This happens because the factory shocks are being stretched beyond their intended design. The Truxxx #304004 Shock Shaft Extensions are the professional solution to this common problem.

Designed specifically for the rear shocks of the Kona and Seltos platforms, these extensions thread onto the top of your factory shock shafts. By doing so, they shift the shock’s operating range back into the "sweet spot," restoring lost downward travel and ensuring your daily drive remains as smooth and quiet as it was on day one.

Check Your Kit First!

Please note that these extensions are already included in the following Truxxx full lift kits. If you are purchasing or already own one of these kits, you do not need to buy this part separately:

• Hyundai Kona: #304023, #304024, #304027, #304029

• Kia Seltos: #304011, #304021, #304024, #304027, #304028

Why the #304004 is Essential for Your Lifted SUV

• Restores Ride Quality: Eliminates the harsh "topping out" sensation that occurs when a lifted vehicle's shock reaches its maximum extension.

• Protects Your Investment: Prevents internal damage to your expensive factory shocks by ensuring they don't slam against the internal bump stops during normal suspension movement.

• Daily Driver Refinement: These extensions ensure that your lifted SUV still handles the commute with the same poise and comfort as a stock vehicle.

• Precision Engineering: Specifically designed for the thread pitch and diameter of the Kona/Seltos rear shock shafts. This is a tailored solution for your specific vehicle.

• High-Strength Construction: Made from Mill Certified Steel
