- Direct fit, no surprisesMarc D.Verified BuyerMay 28, 2026
Lined up perfectly with the original. Install took about an hour with the right press. Solid feel back in the steering, no more clunk over bumps.

Works great so far. Just confirm fitment for your exact trim before ordering — the fitment list on the page was accurate for mine.
