Fitment & Compatibility
Verify the actual drop spindle against DS866, including its hub journals and bracket points. A car's donor model does not identify which Magnum Force or other aftermarket upright is fitted. Match the new hub's lug pattern to the wheel and establish caliper alignment with the supplied shims. Appropriate hoses and fittings are separate. Check the conditional 17-inch wheel envelope behind the spokes as well as through the barrel before completing hydraulic and steering-clearance tests.
