These coil springs are only available as a matching set of front and rear springs in order to preserve optimal vehicle handling dynamics. The relative rate\/frequency of the front coil springs vs. the rear springs is a crucial part of safe vehicle handling. Because of this, AEV increases the rate\/frequency of the front springs in order to maintain an appropriate relationship with the rear springs, across the entire range of rear-biased loading.\u003c\/p\u003e\u003ch4\u003eKit Contents\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.5\" High Capacity Springs Front Pair\u003c\/li\u003e\n\u003cli\u003e4.5\" High Capacity Springs Rear Pair\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cul\u003e\u003cli\u003eJeep Wrangler JK 4-Door 2007-2018\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003ePart Numbers\u003c\/h4\u003e\u003cul\u003e\u003cli\u003eMPN NTH21505AB · UPC 810092171386\u003c\/li\u003e\u003c\/ul\u003e","brand":"AEV","offers":[{"title":"Default Title","offer_id":68166478856508,"sku":"NTH21505AB","price":499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/0136\/3004\/files\/DSC_5670-XL.jpg?v=1794592811","url":"https:\/\/highliftoffroad.com\/products\/aev-4-5-high-capacity-spring-kit-jeep-wrangler-jk-4-door-2007-2018","provider":"HighLift Off-Road","version":"1.0","type":"link"}
