Key Features
- Key Features Upgrades the rear control arm fasteners to 12 mm diameter class 10.9 bolts.
- UMI gives the diameter as 12 mm and the grade as class 10.9 but publishes no length or thread pitch, and no dealer record itemises them either.
- This kit steps the fasteners up to 12 mm class 10.9 with nylon insert lock nuts and washers, and it covers one pair of arms, either the upper or the lower set.
- Listed by UMI as a direct bolt-on upgrade.
- UMI publishes the finish but no salt spray rating, so treat it as normal plated hardware rather than stainless.
- Fit the 12 mm class 10.9 bolt with a washer and a new nylon insert lock nut, leaving it finger tight.
