We had the pleasure of visiting Currie Enterprises of Anaheim, CA., a few months back, and those who know about this vaunted company know why we were honored to take a tour. For those not familiar, Currie has been in business since 1959, and the company started off in a garage as most successful businesses do. Their rise to automotive prominence came quickly, and they are known in the automotive industry for building some of the strongest rear-ends for all automotive needs. So strong in fact, that we just had to put one under our ‘70 Caprice! The security and peace of mind you can get by adding one to your ride is unparalleled, and they are certainly the go-to destination for rear end suspension reinforcement for your build. The Currie housings are so strong that you will no longer worry about battery weight wearing down the axle bearings and losing them while you’re driving. The Fab-9 housing is also strong enough to take any amount of torque our LS3 could throw at it, without jeopardizing a smooth ride.
We wanted to modernize the rear end suspension and after talking to Art Gomez, from Go-EZ Customs in Anaheim, he suggested we add a triangulated four-link. With the lower arm braces and pinion angle handled by Currie, this custom install was sure to be a smooth process. For the addition to be successful, all we would need to do is figure out the angles on the top of the housing. With the stock trailing arms being the weakest link, we called our friends at RideTech who suggested we use their newest 65-70 tubular suspension instead. Tubular suspensions have been around for years and can be seen in race cars and trophy trucks that run the Baja 500. They are considerably stronger than the older stamped metal suspensions. RideTech’s bolt on kits are also one of the easiest kits on the market to install and they perfectly complement the look that we wanted to add to our classic car.
Now follow along, as Art Gomez from Go-EZ updates the suspension by installing a more modern set up on this 42-year-old car.
1. This Currie rear end was ready to be installed and will be able to handle what ever the LS3 can throw at it.
2. The stock rear end was ready to be removed.
3. After unbolting the stock trailing arms, the complete axle was removed with ease.
4. With everything disassembled, we were ready to start installing and fabricating.
5. RideTech supplied us with the lower trailing arms, coils, and shocks that we needed to use for the build.
6. The lower tubular trailing arms dictated where the rest of the suspension would fit.
7. The RideTech arms were fastened down snugly to allow us to remove them when needed.
8. We used universal arms to create the four-link.
9. The arms were measured and mocked up to get the angle that we were looking for.
10. After looking at the angle of the upper arms, they were measured and prepped to be trimmed down.
11. The upper arms were cut down to 8-inches.
12. Art used the Lincoln welder to weld adjusting bungs in place.
13. These upper arms were left to cool off before they were assembled and installed.
14. The frame was cleaned off to allow the weld to bond.
15. The upper arms were assembled and setup to be welded in place.
16. The axle was set to ride height, allowing the upper arms to be mocked up easier.
17. The arms were set in place.
18. Here is another look at the angle of the upper arms as the brackets will need to be welded to the frame.
19. The braces were tack-welded in place.
20. The housing was ready to be removed one last time to allow the last of the welding to be done.
21. The housing tabs for the four-link were tack-welded in place.
22. The tabs were welded on the housing.
23. The frame tabs were also welded and allowed to cool off.
24. The axle was re-installed one last time.
25. We tightened down the cup coils to make sure the coils stayed in place.
26. To ensure that the car had a smooth ride, we used a set of RideTech shocks.
27. The shocks were bolted up.
28. After a couple of hours of work, the Currie rear end was bolted up.
29. This car was ready to roll with a brand new powerful Currie four link rear end!
