Coachbuilder +4" Shackle Kit | 2.25" Rear Lift | Fits Toyota Tundra 2007–2021 Including TRD Pro | Ekstrom Design

The Coachbuilder +4" Shackle Kit is the tallest shackle Ekstrom Design builds for the 2007–2021 Toyota Tundra, including TRD Pro: 2.25" of actual rear lift from a bolt-on swap. It’s the size for trucks matching a lifted front end or living with heavy, permanent loads out back, and Coachbuilder engineers these to be the strongest shackles available for the Tundra. At this height the details matter — the driveline angle changes enough that a carrier bearing drop kit sized for the shackles comes in the box, and it’s smart to confirm rear brake line and ABS harness slack at full droop before you call the job done.

Features

• 2.25" of actual rear lift — the maximum available from a Coachbuilder shackle
• CNC machined from T6 6061 billet aluminum, engineered to be the strongest shackle available for the Tundra
• Eliminates side-to-side flex and improves strength while towing
• Free pivot bushing design with graphite poly eyelet bushings for smooth articulation
• Carrier bearing drop kit sized for the shackles included — torque to 25 ft-lbs on the ground
• Works with OE or any aftermarket leaf pack, the TRD dual exhaust, and the full-size spare
• Compatible with ADS, Bilstein 5100/5160, Fox, Icon, King, OME, and TRD Pro shocks
• Hard black anodized, installs in 45–60 minutes at 70 ft-lbs, made in the USA

The box carries the +4" shackle pair, graphite poly bushings for the spring eyelets, hardware, grease packs, the carrier bearing drop kit, and an install guide. For taller rear setups, the Rear Brake/ABS Relocation Kit adds 2.25" of length to keep lines relaxed, and the Rear Sway Bar Extended End Links +4.00" restore sway bar geometry on lifted trucks.
