Upgrade Your Classic Mopar with the R251-175 Coil-Over Kit
If you're looking to transform the suspension of your classic Dodge Coronet, Dodge Dart, or Plymouth Fury, the QA1 R251-175 Coil-Over Kit is the perfect solution. This innovative kit replaces the traditional leaf spring rear suspension with a triangulated 4-link design, offering numerous benefits that enhance both performance and aesthetics.

- Exhaust Clearance: The kit allows for a 3" bumper exit exhaust, making it easier to customize your exhaust system.
- Optional Sway Bar: Pair your suspension with an optional QA1 sway bar to minimize body roll during hard launches.
- Made in the USA: Quality craftsmanship you can trust, with an industry-leading Limited Lifetime Warranty on single- and double-adjustable shocks.
Specifications
- Fitment: Compatible with Mopar 62-65 B-Body models.
