In my words
Every pit box needs a D1 Hinge Pin Holder PRO-MT 4X4 sitting in it before it needs another set of tires.
Shock geometry changes a car more than a spring swap, and swapping a tower is cheaper than both.
I link straight to the listing so the price you see is the price it sells for today.
What Pro-Line says about it
- Includes a Replacement D1 Mount
- Mount made from Gun Metal Anodized Aluminum
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.
