In my words
Every pit box needs a Rear Arms PRO-MT 4X4 sitting in it before it needs another set of tires.
fitted rear. Spares exist so a broken part costs you a heat race instead of a weekend.
Stock on small-batch sets moves quickly, so the listing is the honest source for what is left.
What Pro-Line says about it

- Made from High Quality & High Strength Plastic
- Thick Arms Designed to Take a Beating
Questions I get about this set
Is it worth doing before I break something?
Usually, yes. A reinforcement part fitted on the bench is cheap; the same part fitted after a DNF costs you a race as well.
Does this fit my car?
The listing carries the full fitment table. Pro-Line lists fitment by platform rather than by year, so compare the part against your current one before the car is in pieces.
