What’s up fellas? Something a little different here… I’m building an 82 Monte Carlo lowrider that will have a 6.0L LS swap (400-425HP) and hydraulic suspension. This car won’t be used for racing, just cruising and highway driving. It’ll also be on 13” wire wheels and 155/80/R13 tires.
The car needs to be able to hit “3-Wheel Motion” (lock the car up and drop the back right or left as you turn and the opposing wheel comes off the ground a couple feet) around corners and I’m told a posi rear will cause issues with “tire chirping” and that I need to do a limited slip and upgraded axles to support the motor swap. This is my first time messing around with axles/gears/diffs, so bear with me if I sound like a noob. 😑
Can you recommend the parts/manufacturers I should go with to make the upgrades to the rear? I am planning to do disc brakes as well, but I need to do more research into swap kits and retrofits from other cars and their compatibility with the 13” wheels. What axles/differential/bearing kits should I be looking at for the OEM 7.5” 10 bolt? I want to use the stock 3.42 gears currently in the stock “1 tire fire” open diff rear. I’ve read that going to 28 spline axles would be a reasonable upgrade as well. What else would need to be changed with that axle upgrade?
I picked up a second rearend for dirt cheap ($50) tonight to build so I don’t have to take the car off the road for a long time to make the upgrades and install the swivel ball mounts for the hydraulic cylinders.
Task/Parts List:
▪️Disc Brakes
▪️Weld-in Reinforcement Truss
▪️Axles
▪️Limited Slip Differential
▪️Powerball mounts for the cylinders
▪️Brake Lines
▪️Bushings
▪️Differential Cover
▪️Surface Prep and Eastwood POR-15 Chassis Paint
Thanks for any help you guys can provide.
