DSS Chevy Camaro 1993-2001 8Cyl auto T56 for Moser 9in conversion-(1350 3-1/2 Alum shaft)...

The Driveshaft Shop MOCA16 (DSS 610034) is a one-piece 3.5 in. aluminum driveshaft built for a 1993-2001 V8 Camaro that has had its factory rear axle swapped for a Moser 9 in. housing. It is meant for the LT1 and LS1 car owner running either the automatic or the T56 six-speed who just bolted in a 9-inch and found the stock shaft no longer lines up, or who wants a lighter, balanced shaft that can live behind a built engine and sticky tires.

What this driveshaft does in a fourth-gen Camaro with a Moser 9-inch

A rear-end conversion changes two things the driveshaft cares about: the distance from the transmission seal to the pinion yoke, and the size of the rear U-joint. A factory shaft is sized for the factory axle, so after a 9-inch goes in it is usually the wrong length, the wrong rear joint, or both. DSS builds the MOCA16 specifically for this conversion. Per the manufacturer it uses a 3.5 in. aluminum tube, solid (non-greaseable) U-joints, a billet transmission yoke on the front and a 1350-series U-joint at the rear to match the larger pinion yoke common on 9-inch builds. Each shaft is high-speed balanced before it leaves the shop. Aluminum keeps rotating weight down compared with a steel tube, which helps the shaft spin up cleanly and stay smooth at highway and top-end speeds.

Symptoms that point to needing this shaft

• Vibration that builds with road speed (not engine speed) after the 9-inch swap, even with new tires balanced.
• The stock shaft bottoms out in the transmission or pulls too far out of the tailshaft once the new rear is installed.
• The rear U-joint will not mate to the Moser pinion yoke because the joint series does not match.
• A clunk on hard launches or shifts, or a squeak at the rear joint, on a car that has added power and traction since the factory shaft was installed.
• Visible dents, a twisted tube or rust-pitted joints on an original shaft that has been through years of drag launches.

How to confirm before buying

Put the car on ramps or a drive-on lift so the suspension sits at ride height, then check the rear U-joint cups against the pinion yoke and note the series stamped on the yoke. Measure from the transmission tailshaft seal to the center of the rear U-joint cups. If the vibration started after a transmission job rather than the axle swap, work through our driveshaft vibration after transmission rebuild checklist first. For the length procedure, see how to measure driveshaft length after a swap, and for joint sizes, our 1310 vs 1330 vs 1350 comparison.

Fitment

Listed for the 1993-2001 Chevrolet Camaro with a V8, automatic or T56 manual, and a Moser 9 in. rear-end conversion. This is not the shaft for a Camaro still on its factory 10-bolt; for a stock rear, look at the 1993-2002 Camaro and Firebird replacement rear driveshaft instead. Because rear-end builds vary, tell us your transmission (automatic or T56) and your seal-to-pinion measurement when you order, or send the year and VIN, so we can confirm the yoke and length before it ships. You can also browse other hard parts for the build.

Install notes

• Driveshaft Shop states that a rear subframe or cradle lock-out kit must be installed before any DSS one-piece shaft, and that skipping it voids their warranty. Confirm your car meets that requirement first.
• Slide the billet yoke into the transmission tailshaft fully, then back it out to the operating position. Check that the tailshaft seal is not cut or leaking; replace it while the shaft is out.
• Use new straps or U-bolts at the 1350 pinion yoke and torque them to the axle maker's spec. Old, stretched hardware is a common source of a rear clunk.
• Check pinion angle after a rear-end swap. A shaft that is perfectly balanced will still vibrate if the working angles at each end do not cancel.
• On a T56 car, this is a good time to address shifter and clutch parts while the car is in the air, such as the T56 billet reverse lockout solenoid delete or the T56 concentric slave cylinder if your application uses it.

Will the MOCA16 fit my 1998 Camaro Z28 with the factory 10-bolt rear?

No. This shaft is built for a Camaro that has been converted to a Moser 9 in. rear end. A car on the factory rear needs a stock-length replacement shaft, which we also carry.

Does it matter whether my car is an automatic or a T56?

Yes. The listing covers both, but the transmission yoke and overall length depend on which transmission is in the car. Tell us automatic or T56, plus your seal-to-pinion measurement, so we can confirm the build before it ships.

What U-joints does it use?

Driveshaft Shop builds it with solid U-joints and a 1350-series rear joint. Check that your Moser pinion yoke is also 1350 series before ordering.

Do I need anything else to install it?

Driveshaft Shop requires a rear subframe or cradle lock-out kit to be installed before any of their one-piece driveshafts, and says skipping it voids their warranty. Plan on new pinion yoke straps or U-bolts and a tailshaft seal while the shaft is out.

Why does my car still vibrate with a new driveshaft?

A balanced shaft cannot cancel bad U-joint working angles. After a rear-end swap, measure and set pinion angle, then check tire balance and motor or transmission mounts.
