  • Direct fit, no surprises
    Marc 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.

  • Shipped fast across Canada
    Jen P.Verified BuyerMay 14, 2026

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

  • Good part, double-check your side
    Steve R.Verified BuyerApr 30, 2026

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

  • Quiet again
    Amrit S.Verified BuyerApr 19, 2026

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