The 350 lb springs are ideal for small block cruising or drag racing with moderate weight reduction, offering a balanced mix of ride quality and improved performance. The hybrid front coil-over system provides a 0¨C3\" adjustable front drop, while the rear springs allow for either a 1\" or 2\" drop to fine-tune the vehicle's stance. Viking's double adjustable shocks feature 19 compression and 19 rebound settings, enabling quick, tool-free suspension adjustments for street, strip, or improved cornering performance.

Our springs are wound from 5160 CrSi premium wire and feature a linear 600 lb\/in rate. UMI's front springs are stiffer than stock to provide increased performance with decreased body roll and a lower center of gravity. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving\/cruising. The ride height is engineered for a 2\" lowering with standard SBC as well as LS power (lightened cars may require spring trimming). The front springs are also suitable for full weight Big Block applications when ?\" nose down rake is desired. They have a tough black powder coat finish and UMI proudly manufactures these premium quality springs in the USA.

The Viking shocks completely transform the truck into a corner carving, drag racing, or street worthy machine with nice ride quality. Many kits in the aftermarket yield a truck with annoying vibrations and a harsh ride, but UMI's design engineers worked to reduce or eliminate that feeling with pinion angle shims, transmission spacer adjustment, longer bump stops and proper leaf spring pins. Greatly improved handling meets factory smoothness with UMI's 6563 kit. 100% Made In USA.\n\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cul\u003e\n\u003cli\u003e100% Direct bolt in design\u003c\/li\u003e\n\u003cli\u003eRear shackle features multiple height setting to dial in the ride height\u003c\/li\u003e\n\u003cli\u003e2WD average lowering 3.5-5 inches: truck weights and styles vary\u003c\/li\u003e\n\u003cli\u003e4WD average lowering 4-6.5 inches: truck weight and styles vary\u003c\/li\u003e\n\u003cli\u003e2.5 degree pinion shims and transmission spacer allow for drive line angle adjustment\u003c\/li\u003e\n\u003cli\u003eU-bolt plates feature shock relocation kit mounting holes: see p\/n 6564\u003c\/li\u003e\n\u003cli\u003eIncludes popular Viking double adjustable shocks to dial in the handling\u003c\/li\u003e\n\u003cli\u003eWorks on trucks with steel or composite leaf springs\u003c\/li\u003e\n\u003cli\u003eAllows ride height adjustments in 1\/2\" increments\u003c\/li\u003e\n\u003cli\u003e100% Made in USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Includes:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cul\u003e\u003cli\u003eUMI- Lowering Kit\u003c\/li\u003e\u003c\/ul\u003e\n\u003cbr\u003e\u003cbr\u003e\u003cb\u003eCompatible With:\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e\n\u003cul\u003e\u003cli\u003e2015-2024 Ford F-150\u003c\/li\u003e\u003c\/ul\u003e","brand":"UMI Performance","offers":[{"title":"Default Title","offer_id":53889015218539,"sku":"UMI-6563","price":1300.28,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1961\/1987\/files\/UMI-6563-1.jpg?v=1789992151"},{"product_id":"gm-abody-umi-shock-spring-kit-1in-lowering-umiss203052","title":"UMI Shock\/Spring Kit, 1in.
