The 4051R rear springs are wound from 9254 chrome silicon premium wire and carry a linear 130 lb\/in rate. The linear rate delivers consistent handling for Auto-x and Pro-Touring use, while the added stiffness reduces body roll and eliminates the floating feeling common to the A-body and G-body platforms. They give a 2 inch rear drop and suit Auto-x, Pro-Touring, corner carving, and cruising. They carry a durable black powder coat finish and are made in the USA.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePosition: Rear\u003c\/li\u003e\n\u003cli\u003eLowering: 2 inch
