Front bumper brass mount for TRX-4

This brass front bumper mount is a scale RC part designed to steady the front bumper and add nose weight on Traxxas TRX-4 based trail crawlers. It gives firmer bumper contact with the chassis and provides an external counterweight (approx. 200g) that assists with front-end tuning during technical crawling.

The set includes the brass mount and all steel hardware required for installation. Installation usually involves attaching the mount to the front bumper assembly using the supplied screws and washers; in several setups the mount permits a small forward shift of the servo to move the front centre of gravity. Use it as part of a considered tuning plan rather than relying on it to correct broader chassis issues.

  • Includes: Brass bumper mount - 1pc
  • Includes: Stainless steel flat head screw 3x12 - 4pcs
  • Includes: Stainless steel round head screw 3x8 - 4pcs
  • Includes: Alloy counter sink washer 3mm - 4pcs
  • Includes: M4x2.5x14.5 screw shaft - 2pcs

A dedicated brass upgrade for TRX-4 scale vehicles to improve front-end stability and enable incremental ballast adjustments when setting up for trail crawling.

If your bumper has been modified, check that the mounting holes and clearance match the mount; minor trimming or new hole positions may be needed for non-standard bumpers.
Yes, the kit contains the brass mount plus stainless steel flat and round head screws, alloy counter sink washers and the M4 screw shafts as itemised in the description.
Adding front ballast may require minor suspension or shock rebound adjustments to maintain desired handling; make small changes and test incrementally.
The mount provides an approximate 200g external counterweight; actual mass can vary slightly between production batches, so treat the figure as a guideline for tuning.
