Front Internal Damper Assembly 135mm - Technical Overview

Designed as a front internal damper upgrade for TRAXXAS UDR models, this 2pcs set uses aluminum 6061 T6 machined components to achieve a low mass, high tensile profile suited to hobby off-road stresses. The construction focuses on consistent fitment and dimensional stability under load.

The sealed damper bodies are filled with a higher concentration suspension oil to stabilise damping characteristics, while the damper shaft diameter has been increased to 5mm to reduce bending and increase rigidity during high demand driving. These changes are intended to improve repeatability and handling consistency when tuning front suspension setups.

The integrated L-shape piggy back reservoir lengthens the internal oil travel path to moderate transient responses and support a more linear damping feel across stroke changes. These internals are provided as direct replacement components for front suspension tuning on compatible TRAXXAS UDR platforms and are suitable for precision hobbyist upgrades.

Specifications

  • Item: Front L-shape Internal Damper (135mm) - 2pcs set
  • Material: Aluminum 6061 T6
  • Model Number: UDR135FX/L
  • Compatibility: TRAXXAS UNLIMITED DESERT RACER
  • Features: Sealed body, high concentration suspension oil, 5mm damper shaft, L-shape piggy back reservoir

Use these internals when a stiffer shaft and extended oil travel are required to achieve stable, repeatable front damping for tuning and performance applications.

What dimensional checks are recommended before fitting?

Measure shock overall length, internal bore diameter and piston travel to confirm the internals will operate without binding in your stock or aftermarket front shock bodies.

How does shaft diameter affect dynamic stiffness?

Increasing shaft diameter to 5mm raises bending resistance and reduces deflection under lateral loads, which can alter damping rate and may require reselecting oil viscosity or spring rate.

Any special maintenance for sealed bodies?

Regularly inspect seals and body surfaces for nicks or wear, verify seal compression after assembly, and replace oil at service intervals to maintain consistent damping performance.

What does the item include?

The kit includes a 2pcs set of front internal dampers intended for front suspension tuning on TRAXXAS UDR compatible models.
