3.75 ID Coilover Springs
PAC & 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.
PAC Racing Springs
PAC Racing Springs is a division of Peterson Spring, the largest privatly held spring manufacturer in North America. PAC Springs has tons of experience, a huge selection of spring rates, many color options, and some of the longest travel springs in the industry. PAC Coilover Springs are made from premium spring wire giving them some of the shortest block heights in the industry. PAC 3.75 ID Coilover Springs have more rate selections and shorter block heights than competitors meaning we can get you the exact right preload and ride height without running the springs solid.
Dual Rate Coilover Springs
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.
Single Rate Coilover Springs
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.
