Timbren FR1504E SES Rear Helper Spring Kit for 2015–2020 Ford Full-Size Trucks

Improve rear suspension support with the Timbren FR1504E Suspension Enhancement System (SES) helper spring kit. Designed for 2015–2020 Ford full-size trucks, this OEM-style upgrade provides additional load support while maintaining a stock-height configuration. The bolt-on design uses the vehicle’s existing suspension mounting locations for a straightforward installation, making it a practical choice for hauling, towing, and demanding work applications.
The FR1504E kit features durable rubber helper springs engineered to work with the factory suspension. With a rated capacity of up to 6,000 pounds, the system helps reduce suspension sag, improve vehicle stability, and provide a more controlled ride under increased loads. Its progressive spring action is designed to remain unobtrusive during lighter-duty driving while offering greater support as the load increases.
This Timbren SES kit includes the required mounting hardware and is finished in black for a clean, discreet appearance beneath the vehicle. It is built for rear suspension applications and is intended for stock-height installations without the need for air lines, compressors, or ongoing pressure adjustments. Confirm vehicle compatibility before installation to ensure the kit matches the specific Ford full-size truck application.
