Carli Tuned 2.5 Coilover/Bypass Package - 4.5in Lift - 2011–2016 Ford F-250/F-350 4x4

The Carli Coilover/Bypass System is one of the most capable off-road suspension systems available, engineered for enthusiasts who demand maximum performance without sacrificing on-road drivability. Combining dual front shocks with height-adjustable coilovers and external bypass technology, this system delivers unmatched control, tunability, and bottom-out resistance.

Featuring King 2.5” front coilovers paired with 2-tube front bypass shocks and 3-tube rear bypass shocks, this setup provides multiple damping zones for superior ride quality and extreme off-road capability. The bypass design allows fluid to move freely during normal driving for a smooth ride, then progressively increases resistance during large impacts for maximum control and protection.

Key Features:

• King 2.5” front coilovers with height adjustability (~1” range)

• Dual front shock setup with 2.5” bypass shocks

• 12” stroke rear 3-tube bypass shocks with oversized rebound tube

• Fully adjustable external bypass tubes for compression and rebound tuning

• Carli-specific, blueprinted shock tuning for heavy-duty applications

• 17-4 stainless steel shock shafts for durability and corrosion resistance

• Coilover conversion brackets for proper mounting and increased travel

• Radius arm drop brackets for proper suspension geometry

• Adjustable track bar to center the front axle

• Stainless steel brake lines for extended travel and improved braking

• Bump stop drops to prevent over-compression

• Caster correction shims for improved steering feel

Performance Notes:

• Provides 4.5” of front lift with significantly increased wheel travel

• Height adjustable to compensate for added weight such as bumpers or winches

• Designed for serious off-road use with excellent on-road manners

• External bypass shocks may produce audible clicking during operation

• Fully tunable suspension for ride comfort or aggressive performance

• Full progressive rear leaf springs increase travel but reduce payload capacity

• Recommended upgrades include differential guard, high mount steering stabilizer, and fabricated radius arms

• Roll cage recommended for aggressive off-road use

• Factory wheels should not be used with oversized tires due to clearance concerns

• Recommended setup: 17–18” wheels, max 9” width, 4.5–5” backspacing with 37” E-rated tires

Vehicle Fitment:

• 2011–2016 Ford F-250 Super Duty 4x4
