Must-Have Toyota Sequoia (XK80) Mods & Owner Upgrades

Solves the single biggest consumer complaint about the 3rd-gen Sequoia: the stepped 6-inch drop behind the sliding third row, creating a 100% flat continuous cargo and overland sleeping surface.

The factory rear floor contains three adjustable shelf positions, but heavy cargo causes the OEM plastic dividers to bend and rattle. Heavy-duty aluminum and birch drawer platforms rest flush with folded 3rd-row seats and easily support 500+ lbs of gear or a dual sleeping mattress.

Individually shields each 60/40 folding seat section and battery faceplate without jamming the power sliding seat tracks.

Unlike rigid plastic rubber tub trays that bind and jam whenever you adjust the power sliding 3rd row, flexible 600D ballistic nylon covers cling tightly to each moving section with heavy-duty hook-and-loop fasteners.

Levels out the factory 2.5-inch front rake while 100% preserving factory shock valving, Fox internal bypass dynamics, and electronic damper calibrations.

Do NOT use cheap top-hat spacer pucks that bolt on top of the strut hat! Top spacers push the suspension past factory down-travel limits, causing upper ball joint binding and CV axle boot tearing. Preload collars preload the lower spring perch inside the factory stroke envelope.

Allows owners of air-ride Sequoias to calibrate rear ride height up by 0.75 to 1.5 inches to perfectly match front leveling kits without throwing dash warnings.

The rear ride height sensors connect from the solid axle to the frame via threaded link rods. Lengthening or adjusting the aftermarket turnbuckle links tricks the ECU into maintaining slightly higher baseline air bladder pressure, eliminating reverse California squat when towing.

Unlocks true 35-inch diameter overland tires (Falken A/T4W, BFG KO3) filling out the massive wheel wells and adding 1.5 inches of pure mechanical ground clearance under the rear differential.

To clear 35x12.50R18 or 295/70R18 tires without rubbing at full steering lock, you must trim or reshape the front lower fender liner bulge and remove the small aerodynamic wind bracket in front of the front tires. An aggressive positive offset (+18mm to +25mm) wheel is ideal; extreme negative offset wheels (-12mm) will rub the body mount cab frame.

Drastically cuts trailer sway, crosswind highway push, and high tongue-weight squat when pulling 7,000 to 9,000 lb travel trailers or boat haulers.

Because the 3rd-Gen Sequoia switched from Gen 2 independent rear suspension (IRS) to a 5-link solid rear axle, rear suspension stability is directly tied to sway bar torsional rigidity. A 24mm or 26mm solid rear anti-roll bar tightens rear lateral body roll by up to 50% without stiffening daily ride comfort.

Looks 100% factory original. Replaces the plastic rearview mirror clamshell shroud with zero dangling cables and no fuse box tapping.

Use the included pry tool to unclip the top seam of the factory mirror cowl. The FitcamX pass-through Y-harness draws power seamlessly from the auto-dimming rearview mirror with zero wire splicing.

Dramatically reduces road rumble and coarse highway roar on coarse chip-seal Canadian highways, transforming the Sequoia into Lexus LX600 levels of vault-like silence.

The Sequoia's massive doors contain large flat outer sheet-metal panels with minimal factory dampening. Covering just 60% of the outer skin and inner door frame with 80-mil butyl mat eliminates metal resonance and noticeably tightens bass response from factory JBL door woofers.
