Deaver Expedition Series 700-1000lb 2″ Lift Rear Leaf Springs For 2005-2023 Toyota Tacoma

Deaver Expedition Series Stage III Rear Leaf Springs (700-1000lb) for 2005-2023 Toyota Tacoma

Part Number: U402-3

Summary: The Deaver Expedition Series Stage III (U402-3) is the ultimate heavy-duty suspension solution for overland-built 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023 Toyota Tacomas carrying constant heavy loads. Fabricated from high-grade 5160 American steel, this 9-leaf progressive pack is specifically designed for vehicles carrying a permanent bed weight of 700-1000 lbs (bumpers, campers, racks, gear). Unlike stiff factory overloads, Deaver’s thinner, high-count leaf design produces a smooth, linear spring rate curve, creating unmatched ride quality and flex while maintaining a 2-inch lift under load.

Features

• Progressive 9-Leaf Design: The use of multiple thinner leaves allows for a flexible, progressive leaf stack to ensure a smooth spring rate curve throughout the complete suspension cycle.
• High-Grade 5160 Steel: Manufactured with premium “American Made” steel provides superior fatigue resistance to ensure long-term durability under heavy overland loads.
• Military-Wrapped Spring Eyes: The fully wrapped main eye provides a redundant safety layer and structural reinforcement to ensure superior durability in extreme off-road conditions.
• Diamond Cut Leaf Ends: Precision diamond-cut ends minimize stress risers and shear points to ensure the longevity of the steel pack.
• Anti-Friction Pads: Inserted between the leafs, these pads reduce metal-on-metal contact to ensure a quieter operation and smoother suspension articulation.

Technical Specifications

Fitment

• 2005-2023 Toyota Tacoma (2WD & 4WD)
• Critical Note: Designed ONLY for trucks with 700-1000 lbs of constant weight in the bed (e.g., campers, drawers, heavy bumpers). Installing on a stock weight truck will result in a harsh ride and excessive lift.

What’s Included

• Includes Complete Rear End Package
• (2) Deaver Stage III Leaf Springs (Driver & Passenger Specific)
• (1) U-Bolt Kit
• (1) Bushing Kit

Why Choose This Product?

• Engineering Advantage: By using a higher count of thinner leaves, Deaver eliminates the harsh “step” found in factory overload springs, providing a linear compression rate that absorbs small bumps while supporting massive weight.
• Performance Benefit: This system stabilizes heavy overland builds, reducing rear-end sag and sway while restoring suspension up-travel for better off-road articulation.

Frequently Asked Questions

Will this fit my stock Tacoma?
Physically yes, but it is not recommended. These springs are tuned for 700-1000 lbs of constant weight. Without that weight, the ride will be very stiff and the rear will sit too high.

Does this kit include bushings and U-bolts?
Yes, this specific package comes complete with a new U-bolt kit and a fresh bushing kit, so you have everything needed for installation.

How much lift will this provide?
It is designed to provide approximately 2 inches of lift after the 700-1000 lb load is applied. If your truck is lighter, the lift height will be significantly higher.

Are the sides interchangeable?
No, these springs are driver and passenger side specific to account for the Tacoma’s weight distribution (gas tank lean).
