Eibach 3.75 ID Coilover springs are designed to fit 3.0 coilovers from Fox, King, Sway-A-Way and Radflo. The clearance between the body and spring allows room for the dual rate nuts and spring slider.
Eibach is one of the original coilover spring manufacturers and has the experience required to make quality off-road springs. By using premium manufacturing techniques Eibach springs are straight and square in order to prevent bowing. Eibach springs come standard with silver powerder coat, and some are available in red. Eibach coilover springs are some of the highest quality in the industry.
Fox & King Coilovers can use dual rate springs, which means there are separate upper and lower coilover springs which are separated by a plastic slider. When the plastic slider hits two stop rings on the body only the lower spring continues compressing and the spring rate drastically increases. When properly designed this transition will improve handling and increase bottoming control without being harsh. PAC & Eibach coilover springs are designed for dual rate applications.
Some Fox & King Coilovers are designed to hold a single spring, also known as single rate coilovers. By holding a single coilover spring on the shock they provide a small package which is easy to mount. 3.75 ID Eibach and PAC Coilover springs are designed to be used on single rate spring applications such as OEM Replacement Coilovers and Short Travel Shocks.
