Fitment & Compatibility
Check DS869 against the fitted ProSpindle before assembling the new hubs. Its bearing fit, bracket attachment and wheel bolt pattern must agree with the kit. Account for the published wheel-position change when confirming fender space and wheel offset. Appropriate flex lines and chassis fittings are additional. Compare the entire nominal 17-inch-or-larger wheel section with the caliper profile, then verify free rotation, hose movement and alignment before bleeding and bedding.
