Show original supplier description
The GM 23418311 is a genuine rear leaf spring engineered to support the weight of your GMC Sierra 1500 or Chevrolet Silverado 1500 and maintain vehicle poise over uneven terrain. This leaf spring is designed for left and right positions and is a direct replacement for various OEM part numbers, including 15895992, 20840009, and 23208339. This leaf spring is specifically designed for 1500 series 4WD models. It is compatible with regular cab configurations and specific 1/2 ton codes such as AAJ5 and AAJ6. The part is intended for use without the enhanced tow package. It is crucial to order by code to ensure correct fitment. Please note that related components, such as the u-bolt and nut, cannot be reused and must be ordered separately. This GM Genuine Part is designed, engineered, and tested to rigorous standards and is backed by General Motors, ensuring quality and reliability for your truck's suspension system.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
