Product Overview QA1's Heavy Duty Pro Rear Systems are the perfect solution to add coilovers to your car or truck. Designed for any vehicle with a 1700-2600 lbs. rear axle weight, this kit includes all the necessary hardware and bracketry for a seamless installation. With double shear bracketry and increased spring rates, it ensures the strength and support you need for street and race applications. This simple weld-on kit features axle mount bracketry, upper shock mounts and tubing, and fully adjustable QA1 coilover shocks and springs. Ride Height Adjustability Our axle-mounted brackets offer increments of adjustment, and the coilover shock allows for fine-tuning. Combined, you will have a total of 9 of ride height adjustability, giving you full control for your desired stance.

Affordable performance air filter
I was skeptical at first. How can such a quality performance air filter be so affordable? It fits perfectly and seems to perform and look exactly like the other name brand layered cotton gauze, steel meshed lifetime air filter. I sprayed some K&N oil on this thing and it feels like the engine is breathing a little easier now and performing a little better. As with anything new, your mileage will vary.
