    Product Details

    ⚠ Flat Tire Ready

    At only 6.5" (165 mm) tall, this jack slides under a fully loaded semi even with a blown-out flat tire — when ground clearance is at its absolute lowest.

    1

    Fits Where Others Won't — 6.3" Entry Height

    A 6.5" (165 mm) minimum entry height is purpose-built for flat tire roadside service. When a semi drops on a blown steer or drive tire, clearance disappears fast — this jack still gets under. No cribbing, no waiting for another jack.

    2

    Full Load, Flat Tire — No Problem

    Rated 80 Ton — handles fully loaded Class 8 tractors and trailers at maximum GVW. Whether it's a steer axle at the roadside or a drive axle in the shop, it lifts the real weight, not just the empty frame.

    3

    Built for Commercial Truck Tire Service

    The standard for commercial truck tire shops and fleet maintenance bays. Positions precisely under front steer axles, drive axles, trailer axles, and frame rails of 18-wheelers — even under extreme low-clearance conditions caused by flat tires, overloads, or suspension drop.
