We love to make our Camaros fast, and to that end, we sometimes find ourselves straying off the GM reservation and using parts from other manufacturers. Ford guys have been stuffing GM engines into their street rods for decades, so we shouldn't feel any shame … but we sometimes do. The most commonly borrowed Blue Oval part is the venerable 9-inch rearend. Its modular design and strength makes it a common sight under Camaros—both at the dragstrip and twisty track.
Currie Enterprises now has a way to make the use of this non-GM part a bit less glaringly obvious. Their Track 9 housing can be had with a GM-style rear cover incorporated for those who want to keep their Camaro looking properly GM to those who peer underneath.
01. The housing starts with 3-inch, 0.188-inch wall steel tubes, which are first cut to the standard width for a first-gen Camaro. Currie can also do custom widths.
02. The Currie Track 9 housing was originally designed for the NASCAR guys. The idea was that they could pull the rear cover for a quick inspection instead of having to pull the axles and third member. NASCAR eventually outlawed it since they felt the cover was another spot where a car could leak fluid onto the track if the crew was in a hurry and forgot to use sealant. It's a great piece for the guy who wants the benefits of a 9-inch without it being glaringly obvious.
03. Before welding the axletubes to the Track 9 housing, Currie bolts on a third member casing. This provides structural rigidity to the housing and reduces the amount of warping during the welding process.
04. The axletubes are then inserted into the housing and measured to make sure they are the perfect length. A steel guide rod ensures everything is lined up perfectly straight.
05. A jig and a level are used to make sure the ends are properly oriented. In regards to the ends, Currie offers several options. One is a billet Torino-style, large bearing end that accepts Ford rear brakes. Another option is a hybrid end that uses the same bearing but accepts GM rear drum or disc brakes.
06. Once everything is properly situated, the tubes and ends are tack-welded in place.
07. Once everything is properly situated, the tubes and ends are tack-welded in place.
08. The housing then goes over to their welding room where everything is fully MIG-welded using a rotating fixture.
09. Currie offers laser-cut spring pads for various Camaro applications, including mono- and multi-leaf.
10. No matter how many jigs and fixtures are used, the housing will warp during the welding process. It is for this reason Currie sends the fully welded housing to their pneumatic station where the housing is made perfectly straight. This is critical to long bearing life and leak-free operation.
11. The rear is then sent to the blast cabinet where every spec of rust is removed. At this point it's ready for paint or powdercoat. The housing can accept either an optional LPW aluminum cover with carrier cap stabilizers or a plain steel cover. Either way, the housing will help keep your use of Ford parts on the down-low. The housing with a plain steel cover, third-member studs, and spring pads prices out at $645. Upgrading to the aluminum LPW cover adds $215 and powdercoating runs another $150.
