Gabriel Gas Shock Absorber - Hendrickson Intraax/Vantraax Trailer Suspension 17.46 in Extended - 85738 680509 A85738

Put the damping back into a trailer that has started to buck and hammer with this Gabriel Gas Shock Absorber distributed by FleetPro Parts & Tires. It is the OE-grade unit for Hendrickson Intraax and Vantraax trailer suspensions and for Reyco trailer suspensions, replacing shocks that have gone weak or started to leak. Once a shock stops controlling axle movement, the load works the air springs and bushings instead, and the tires pay for it with cupping and scalloped wear. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, trailer repair shops, and owner-operators nationwide.

Even Damping: The Gabriel Trailer Shock Advantage

This gas shock runs 17.46 in extended and 11.69 in collapsed, matched to the Hendrickson top mount, underslung and Intraax brackets it serves, and it carries a matching ES36 eye at both ends — 0.75 in ID through a 1.75 in sleeve, upper and lower. That common mount is what makes it a straight bolt-in on the HT and Intraax series without adapters. The dust tube keeps grit, salt and stone chips off the piston rod so the seal is not chewed up from the outside, and recoil cutoff softens the top of the stroke when an axle drops away over a rough crossing.

Replace shocks in pairs across the axle so both sides damp the same, and check the bushings and mounting hardware while the unit is out.

At FleetPro Parts & Tires, we know a suspension job is only right when the part is right. This shock is a direct replacement for highly searched industry numbers including Gabriel 85738, Hendrickson 680509, A20886 and Reyco 2352401.
