The RE-043/P4 40-series wide offset wheel set is specified for Traxxas Revo and HPI Savage 21 / HPI Savage 25 chassis as a wider track aftermarket wheel option. The product text lists a purple finish and a pack quantity of two pairs (4 pcs). Use these wheels where increased track width or altered clearance is required without changing the basic truck layout.
Installation guidance: these are wheel-only items in the listing, so verify hex size and hub spacing on your vehicle prior to fitting. Required spacers, hex adapters or wheel nuts are not listed and must be sourced separately. Confirm tyre sizing and clearance when pairing tyres to the wider offset to avoid rubbing.
Setup notes: fitting wide-offset 40-series wheels modifies scrub radius and lateral track, influencing steering input and suspension load paths. Expect measurable but manageable handling shifts; fine tune camber, toe and ride height to restore competitive balance for bashing or track use.
Select RE-043/P4 when a racing-influenced wide-offset wheel is needed for Revo or Savage platforms, and confirm hub and hex fitment before finalising the build.
