ICON Vehicle Dynamics K53004T Stage 4 Suspension System with Tubular Upper Control Arms

The ICON Vehicle Dynamics K53004T Stage 4 Suspension System delivers maximum performance and exceptional ride quality for Toyota Tacoma owners seeking to enhance their truck's capabilities both on-road and off-road. This complete suspension system is engineered to increase wheel travel and damping ability, translating into outstanding vehicle control and a superior driving experience.

Front Suspension Components:

• 2.5-inch Extended Travel coilover shocks with remote reservoirs for exceptional cooling properties and consistent performance under hard use
• ICON-engineered Eibach coil springs (650 lb/in standard rate, 700 lb/in available for heavier loads) providing superior vehicle feel through the full range of travel
• Height adjustable from 0-3.5 inches of lift on 2005-2015 models, or 0-2.75 inches on 2016-2023 models
• Corrosion-resistant CAD plated shock bodies with 7/8-inch shafts
• 6061 aircraft-grade aluminum CNC machined components
• FK rod end bearings for extended longevity and minimal deflection

Tubular Upper Control Arms with Delta Joint Technology:

• Tubular steel construction for added strength, durability, and weight reduction
• ICON's patented Delta Joint (U.S. Pat. 10,731,700) combines the durability of a ball joint with the performance of a traditional uniball
• Zinc-plated housing with tough grease seal for corrosion resistance and protection from the elements
• Metal-on-metal construction with greaseable design for extended service life and noise-free operation
• Corrected front-end geometry with built-in additional caster for improved handling
• Allows full bump and droop travel of the front suspension while eliminating bind
• Adds a full inch of droop travel when combined with extended travel coilovers

Rear Suspension Components:

• ICON 2.0 Aluminum Series Remote Reservoir rear shocks with 5/8-inch shafts
• Vehicle-specific valving that balances front-to-rear performance
• Progressive Add-A-Leaf kit that replaces factory overload leaves
• Lowers rear spring rate by approximately 10% for a more compliant ride quality
• Provides 1.5 inches of rear lift over stock height

Performance Benefits:

• Increased wheel travel and ride quality over stock suspension
• Accommodates larger, more aggressive wheel and tire combinations (33-inch tires without trimming recommended)
• Vehicle-specific tuned shocks for superior damping and control
• Improved suspension component clearance
• Bolt-on installation with no cutting or welding required

System Components Include:

• 58735 - Extended Travel 2.5 VS RR Coilover Kit (1)
• 58450DJ - Tubular UCA Delta Joint Kit (1)
• 51100 - Progressive Add-A-Leaf Kit (1)
