What You're Looking At
This is a standard hydraulic shock absorber, not an air spring, not a strut - a straight shock. On Mack and Volvo chassis it mounts either front or rear depending on the suspension package the truck left the factory with, so don't assume position off the part number alone.
65494 covers a good chunk of the Mack/Volvo heavy-duty lineup because these two brands share a lot of chassis engineering under the hood - same corporate family, similar suspension geometry on a lot of models. That's why one shock number spans both nameplates instead of needing two separate parts.
Bushings top and bottom are the usual wear point along with the shock body itself. If the truck's bouncing more than once over a bump or you see oil weeping down the shaft, that's your sign it's done.
How These Numbers Cross
SH65494, 65130, 85061, A85061, D65494, F65494, and M85061 all land on the same physical shock - different prefixes are just different suppliers or repackagers running the same core casting and valving. This happens constantly in truck parts; one manufacturer builds it, five others slap their own label on it.
Where guys get burned is length and eye/stud mounting style. Even when the base number crosses clean, always check overall extended and compressed length plus whether the ends are eye-to-eye, stud-to-eye, or stud-to-stud. Mack and Volvo both ran multiple shock lengths across their heavy-duty line depending on ride height and axle config.
Don't trust the number stamped on a shock that's been on the truck for eight years and covered in road grime - grab the full part number off the box if you kept it, or better yet pull chassis info by VIN. That's the only way to know for certain you're not ordering a shock that's an inch short in either direction.

Frequently asked questions
Does 65494 fit my Mack truck?
Likely, but it depends on which suspension package your truck has and whether it's front or rear position. Give us your VIN or the number off the old shock and we'll verify before you order.
Is 65494 the same as the Gabriel/Meritor M85061?
Yes, M85061 cross-references to 65494 - same shock, different brand label. Just double check length and mounting ends match what's coming off your truck.
What's the difference between 65494 and D65494 or F65494?
Those are supplier-specific prefixes on the same base part, not different shocks. They interchange, but always confirm mounting style and length against your old unit since Mack/Volvo ran several variants.
