    Noticeable difference

    With a new ford performance differential cover and this full tilt boogie lower mount with new cross axis joints. It eliminated my wheel hop and with nitto new drag radials it hooks. No more wheel spin on my launch. I didn't expect such a big results. Would definitely recommend this to a friend

    Great product

    This product is great really helped out with finishing my IRS build, no more weird vibrations. this really helped finish the full bushing kit on my cobra and helped illuminate the wheel hop FTBR has great products. America muscle was a great help as well. we had a little hiccup during the ordering process but they did their part to square it all away and couldn't be any happier with the service and product.
