Serious about drag racing? These Moroso 47520 rear coil springs are built for one job: optimizing weight transfer off the line. They don't come as a pair of identical springs. Instead, the right-side spring is specifically wound stronger than the left-side spring. Why? In a rear-wheel-drive V8 car, the engine torque and drivetrain rotation (the 'pinion effect') make the car want to lift differently on the left and right sides during a hard launch. Using these left/right specific springs helps the rear end lift more evenly and consistently, putting power down better and making your launches more repeatable pass after pass. Moroso is a legendary name in drag racing parts. These springs are made in the USA. They're a direct replacement for your stock rear springs but are engineered purely for performance at the strip. If you're building a bracket car or a street/strip machine and chasing those precious hundredths of a second, this is the kind of detailed tuning part that makes a difference. Just make sure they're compatible with your car's model and rear suspension setup.
