2-Piece Summit Kit 2.25" - 6th Gen 4Runner

The Peak 2-Piece Summit Kit – 2.25″ Lift raises the front of your 4Runner about 2.25″ and adds Peak tubular upper control arms for corrected caster and expanded alignment range. The top spacer + lower spring seat adapter approach adds height while keeping shock performance and daily ride quality predictable.

Features:

• ~2.25″ front lift via top-mount spacer + lower spring seat adapter
• Includes Peak tubular upper control arms for added caster and droop clearance
• CNC-machined billet aluminum collars with anodized finish
• Direct bolt-on installation using factory locations
• Works with factory-style front struts; preserves usable shock travel
• Professional alignment recommended after install

Full Lift

This system splits lift between an upper spacer and a lower spring seat adapter to hit the 2.25″ target while maintaining shock travel and damping behavior close to stock. Avoiding excessive preload helps keep on-road comfort and predictable control on rough surfaces.

Summit Kit Components

The kit includes matched top-mount spacers, lower spring seat adapters, and a pair of Peak tubular upper control arms. UCAs add positive caster and extra droop clearance, improving steering stability, alignment range, and tire-to-fender clearance through the suspension arc.

Fitment & Tire Clearance

Engineered for the 2025+ 4Runner. The added front height eases nose-down stance and creates room for accessories and larger tires. Final clearance depends on true tire size and wheel offset; verify clearances after installation.

Easy Bolt-On Installation

Everything mounts to factory locations with common tools no cutting or permanent modifications needed. After installation, schedule a professional alignment and re-torque suspension hardware after initial miles or off-road use.
