Our shock mounts use an oversized bearing for maximum strength, sleeved down to either 10mm or 12mm to fit your shocks using these bushing inserts. If you have purchased a used set with the wrong set of inserts for your shocks, you'll need these.
10 mm fits the majority of Miata shocks, such as Tokico, Koni STR.T (orange), Bilstein, KYB and stock.
12 mm fit Koni Sport (yellow).
If you're not 100% sure of your shock shaft diameter, please measure before you order these! We've heard that some shocks from certain suppliers don't always match the shaft diameters above.
Sold individually, two needed per shock, four per car.
