LXAUTOPCH leaf spring insulator pad bushings 8pc kit — OE fit 2C3Z-5586-AA, reduces noise and restores ride quality

LXAUTOPCH leaf spring helper insulator pad bushings (part 2C3Z-5586-AA) are replacement rear leaf spring insulator inserts designed to restore proper fit and reduce noise on compatible Ford F-Series and E-Series trucks.

These bushings are molded to fit between the leaf spring and its mounting pad, providing cushioning and alignment where original rubber inserts may have deteriorated. They come as an 8-piece kit that matches OE part number 2C3Z-5586-AA and are intended for a range of Ford model years and platforms. With a one-year warranty, the set offers a straightforward maintenance part to help preserve ride quality and reduce metal-on-metal contact in older or high-use trucks.

Which Ford models and years are they compatible with?

These insulator pad bushings are manufactured to match the fit of the OE reference 2C3Z-5586-AA and cover many popular Ford trucks and vans. They are compatible with numerous F-Series and E-Series model years and specific truck platforms where this insert is used.

• Fits Ford F-150 model years around 2004–2014.
• Compatible with F-Series Super Duty platforms from roughly 2005–2010.
• Works on Ford Ranger applications circa 2004–2011.
• Fits E-Series vans including E-150, E-250, and E-350 Super Duty from about 2008–2021.

How do these bushings improve the vehicle's performance or feel?

Installed between the leaf spring and its mounting pad, the insulator pads reduce direct metal contact, which lowers squeaks and vibration. They also help keep the leaf spring centered in its perch, supporting more consistent handling under load.

• Dampens vibration and reduces squeak from worn pads.
• Improves alignment of the leaf spring in its mount.
• Helps maintain ride consistency when the original inserts are degraded.

What does the kit include and how is it sold?

The LXAUTOPCH offering is supplied as an 8-piece set that provides replacement inserts for multiple mounting points, and there’s also a 4-piece option available if fewer locations need service. Each kit carries the OE part number reference and is covered by a one-year warranty for defects.

• Part number: 2C3Z-5586-AA (also listed as 2C3Z5586AA).
• Available in 4-piece or 8-piece sets — this listing is for an 8-piece kit.
• One-year limited warranty included.

How easy is installation and what tools are typically required?

Replacing leaf spring insulator pads is usually a routine repair for anyone with basic mechanical skills and common hand tools. Most installs require the vehicle to be safely supported and the spring perch area cleaned so the new inserts seat properly.

• Basic hand tools: sockets, breakers, and pry bar may be needed.
• Vehicle support: jack stands or a lift for safety during removal/installation.
• Cleaning the perch area improves fit and helps prevent premature wear.
