2021-23 Ford F-Series Billet Shackle with 1" Drop
2021-23 Ford F150 Suspension Systems with Rear Leaf Packs

 

ICON Vehicle Dynamics introduces complete Suspension Systems for 2021-23 Ford F150 4WD standard editions (3.5 to 4.5-inch) and Tremor edition (2.5 to 3-inch) featuring our Raptor Multi-Rate Rear Leaf Springs. To make these high performance rear leaf springs possible in non-Raptor trucks we've developed a set of billet 1" drop shackles, which are included in each of these suspension systems and also available as a stand-alone product. The rest of the components that make up these systems have been previously introduced, so let's take a closer look at the Billet Shackles themselves before moving on to the complete kits.

Dial in your Ford F150 or F250's rear suspension height for leveling or to match suspension lift components for a lifted, level ride. These shackles yield 1" of drop in the rear suspension height. CNC machined billet aluminum construction is both great looking and durable. A factory style bonded bushing provides maintenance-free, quiet operation.

KEY FEATURES:

• Provides 1" of rear suspension drop
• CNC machined 6061 aircraft grade aluminum
• Bonded bushing for maintenance-free performance and durability
• Fits 2010 and newer Ford F150 and F250 trucks

ICON designed these billet shackles specifically to make it possible to install ICON Gen2 Raptor Multi-Rate Leaf Packs into 2021-23 F150 Standard or Tremor models. This makes them a perfect complement to our 2.5 VS Front Coilovers If you're not yet familiar with our Gen2 Raptor Multi-Rate Leaf Pack, here are the pertinent details:

KEY FEATURES:

• 3 user-adjustable spring rates for unique vehicle setups
• Triple military wrap front eyelet and rear half wrap for increased durability
• Rebound leaf reduces severe axle wrap
• Leaf separators and tip inserts reduce noise and friction while increasing ride comfort
• Direct bolt-in to OEM spring location makes for an easy install
• “ICON 1K” tested under rigorous off-road conditions to validate tune, performance, strength, and durability

The "Multi-Rate" feature of these rear leaf spring packs makes it possible to dial in your truck's rear spring rate/lift height to accommodate a wide range of use cases and weight ranges, from empty-bed weekend warriors to fully outfitted overlanders to tool-laden work trucks, while optimizing suspension performance, wheel travel and ride quality.

For ordering convenience we've configured a range of Complete Suspension System "Stage" Kits for 2021-23 Ford F150 and F150 Tremor, that include these Billet Shackles and the Gen2 Raptor Multi-Rate Leaf Packs, along with our Delta Joint Pro UCA's and a variety of front coilover and rear shock configurations. Please scroll down for complete product information on those kits.

COMPLETE SUSPENSION SYSTEMS

These billet shackles make a range of high-performance 2.5 - 3 inch suspension systems possible for the 2021-23 Ford F150 non-Tremor models. The shackles allow the installation of ICON's Raptor Rear Leaf Packs, at a ride height that matches our 2.5 - 3" coilovers and shocks for Tremor, plus ICON UCAs with Delta Joint PRO and our ductile iron steering knuckles. These components form the basis of our 2.5 - 3 inch Leaf Pack Suspension Systems for 21-23 F150, with 5 stages of performance to choose from.
