- 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.

Ordered on a Monday, had it by Wednesday in Calgary. Greasable fitting is a nice touch. Quality looks on par with OEM.

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

Replaced both sides at the same time. The knocking noise is completely gone. Boot quality feels durable.
