OEM Air Shocks

[Dan Marx]

Attached is pix of a DELCO REMY JAC PAC Air Shock system that I believe has a GM application, cars 1965-'72?? This comes with an OEM air compressor that is vacumn actuated. Does anyone know if this is OEM application or perhaps a dealer add on?

Thanks

Back then, AC-Delco might have been an OEM "internal" GM supplier, but they also sold products in the auto supply network. Therefore, the OEM AC-Delco would not have any "AC-Delco labels on them, or the specific AC-Delco aftermarket color on them.

Additionally, at least in later years, OEM GM air shocks had unique fittings on them rather than the more common screw-on fittings of the aftermarket items, in addition to an on-board compressor run an a level sensor attached to the rear suspension/rear axle housing. "Automatic Level Control".

Aftermarket air shocks had their screw-on fittings on the shocks and a common air line with the air inlet port installed somewhere in the rear bumper/license plate area.

In the case of the Jac Pac, it would have had an electric air compressor and an interior control switch. Possibly with a pressure gauge, too? As I recall, the Jac Pac was sold in the 1968-'71 era?

In the 1968 timeframe, AC-Delco also had a particular line of shocks which were "dismantle-able". Kind of like the Carter AFB Strip Kits, the shocks came in pairs and with valving sets to tailor the compression/extension valving to what the customer wanted. Kind of neat, I thought, at the time! Obviously, kind of messy too, having to drain and re-fill the shock oil. Didn't last too long in the market place, though . . . something of a pre-cursor to the later Gabriel Strider adjustable shocks, which were externally-adjustable.

Just some thoughts,

Thanks for the reply. This set comes with an adjustable pressure guage that mounts on the dash. The pump is vacumn acutated and will pump the shock to 175 psi.

The JaxPac kit with the compressor and under dash control panel was an aftermarket add-on kit.
