Description
Product Overview
The MOTOKU seat bracket is a precision‑engineered component crafted from high‑strength steel to replace or reinforce the factory seat mounting hardware on Chevrolet Silverado and GMC Sierra trucks. Designed for model years 2008‑2014, the bracket matches the original mounting points of the Silverado 1500, 2500HD, 3500HD and the Sierra 1500, 2500HD, 3500HD. Each unit weighs only 4.6 ounces, yet its reinforced construction provides superior load distribution, reducing stress on the vehicle frame and extending the life of the seat assembly. The part number 25879577 corresponds to the OEM specification, ensuring a perfect fit without the need for modifications.
Usage
This bracket is ideal for a range of real‑world applications. Fleet operators can install it to reinforce seats that endure constant loading and unloading, while off‑road enthusiasts benefit from the added stability when navigating rough terrain. The bolt‑on design means the bracket can be installed in a standard garage or on‑site with basic hand tools, making it suitable for both professional service bays and DIY owners. It is especially useful for trucks that have been lifted, have aftermarket seats, or require a more rigid mounting solution for heavy cargo or passenger loads.
