{"product_id":"allstar-performance-all64234","title":"Allstar Performance Spring Pre-Loader for 14in Spring ALL64234","description":"\u003cp\u003ePre-loader allows use of a softer spring rate that is \"pre-loaded\" at ride height. The pre-loaded spring will have less rate increase as the suspension travels. For example, a 150 lb\/in spring can be pre-loaded to 400 lbs. at ride height, but still only increases at a rate of 150 lb\/in as suspension travels. The entire unit may also be exchanged with another unit with a different rate spring pre-installed to allow spring rate changes without affecting ride height. Commonly used on the rear coil-overs, pre-loader requires 3\" I.D. spring, includes a thrust bearing set and fits most shocks. Note: Unit is typically installed with slotted inner half towards the shock body. Always check components for possible interference.\u003c\/p\u003e\u003cp class=\"pst-subhead\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUniversal application.
