SCITOO Drop Lowering Shackles for Ford F-150 1-2in Adjustable Kit — OEM Fit, Painted

SCITOO's adjustable drop lowering shackles (OEM 513220) let you safely lower or level your Ford F-150 by 1–2 inches while preserving ride quality and factory fitment.

Designed specifically for multiple 2015–2022 Ford F-150 trims, this adjustable leaf spring shackle kit provides a direct-fit replacement that follows OEM specifications. Finished with corrosion-resistant paint and factory-style construction, the kit aims to restore correct suspension geometry when lowering or leveling, improving stance without extensive modification. It’s engineered to be a bolt-on solution for models including XL, XLT, Lariat, King Ranch, Platinum, Limited, Raptor, Tremor, Police Responder, and SSV, matching original part number 513220.

How does this shackle kit alter my truck's ride and stance?

Lowering shackles shift the rear axle position within its mounting points to reduce rear ride height by 1–2 inches, giving a more level and aggressive profile. Because this kit is made to OEM dimensions, it keeps the leaf spring alignment and suspension geometry near stock, which helps retain predictable handling and comfort.

• Adjustable drop range: 1"–2" to fine-tune rear height.
• OEM-compatible dimensions for correct spring alignment.
• Painted finish to resist rust and extend service life.
• Direct-replacement part number 513220 for simple swap-in installation.

Will these shackles fit my specific F-150 model and year?

SCITOO lists compatibility across many F-150 trims from 2015 through 2022, but fit depends on engine and trim combinations and original suspension options. Always verify fitment by entering your vehicle make, model, year, and trim in the seller’s garage tool or compare to your existing OEM part number before purchase.

• Covers XL, XLT, Lariat, King Ranch, Platinum, Limited, Raptor, Tremor, Police Responder, SSV.
• Compatible with engines listed by SCITOO (2.7L–5.0L and 3.0L/3.3L variants where specified).
• Designed as a direct replacement for OEM 513220.
• Check the garage fitment tool or OEM part reference prior to ordering.

What materials and protection are used to ensure durability?

The shackles are manufactured to meet production-level quality controls and are finished with a painted coating that resists corrosion in typical road and weather conditions. This surface protection helps preserve structural integrity and appearance over time, especially in climates exposed to moisture or road salt.

• Factory-style painted finish for corrosion resistance.
• Built to OEM-matching tolerances for consistent performance.
• Quality control testing to ensure fit and function before shipping.
• Replacement kit designed to integrate with existing leaf springs and mounting hardware.

How difficult is installation and what support is available?

Installation is intended to be a direct swap for the OEM shackles, but it requires basic suspension tools, jack stands, and mechanical knowledge to safely support the vehicle and torque mounting hardware. SCITOO provides customer support if you encounter fitment or installation questions, and following the vehicle-specific instructions reduces risk of issues.

• Direct-replace design minimizes custom fitting or fabrication.
• Requires standard hand tools, jack and stands, and torque specification adherence.
• Customer support available for installation guidance and troubleshooting.
• Confirm fitment with the garage tool to avoid returns or mismatched parts.

Who is this for: Drivers who own 2015–2022 Ford F-150 models and want a factory-compatible way to lower or level the rear by about 1–2 inches without altering leaf springs or investing in complex suspension swaps. This kit suits owners seeking improved stance with OEM-style durability, installers performing routine suspension updates, and anyone who needs a plug-and-play replacement for part number 513220. Always confirm vehicle fitment before purchase and follow safe installation practices.
