5", 6", 7" Hanger and Rear Flip Kits - 1980-1997 Ford F-Series

Sky's 5", 6", & 7" Rear Shackle Flip Kit – 1980–1997 Ford F-250/350 & More

Upgrade your rear suspension with this heavy-duty Shackle Flip Kit, designed to provide 5", 6", or 7" of lift while significantly improving ride quality and axle articulation. By repositioning the shackle below the leaf spring, this kit allows your suspension to cycle more naturally, reducing stress on your springs and improving both comfort and performance.

This system replaces both the rear shackle hanger and spring hanger with laser-cut, CNC-formed 1/4" and 3/16" PO steel brackets, built to handle serious off-road or towing demands.

Key Features:

• Tailored Lift Options – Choose from 5", 6", or 7" of rear lift.
  • 5" kit uses 2" RFK Hangers
  • 6"/7" kits use 4.5" RFK Hangers
  • 7" kit includes 1" lift shackles

• Improved Suspension Geometry – Keeps pinion angle close to stock to prevent driveline vibrations and premature wear.

• Smoother Ride Quality – Allows springs to follow their natural arc for better compression and rebound travel.

• Axle Positioning Flexibility – Spring hangers include three mounting holes to fine-tune axle location.

• Heavy-Duty Construction – Made in the USA from premium steel and built to outlast OE components.

Application:

• Fits: 1980–1997 Ford F-250/350, 1992–2018 E-350, 1980–1996 Bronco/F-150 (requires additional frame drilling).

• Designed for 3.5" wide leaf springs.

• Will not fit 1978–1979 models without re-drilling frame pattern.

Includes:

• Rear Shackle Flip Brackets

• RFK Spring Hangers (varies by lift height)

• Grade 8 Hardware Kit for frame mounting

• Reuses OE hardware for shackle-to-hanger connection

Installation Notes:

• All factory hangers must be removed prior to installation.

• Do not fully tighten any components until the system is squared and aligned with axle installed.

• Die grinding may be required due to factory frame variances.

• Final pinion angle and axle centerline should be verified and adjusted after assembly.

This kit is ideal for serious OBS builds, off-roaders, or anyone looking to correct suspension geometry while lifting the rear of their truck the right way.
