Misakomo Seat Spacer Riser for 2005–2021 Tacoma & 4Runner — CNC aluminum satin-black, 1/4"–1½" lift

Misakomo seat spacer riser lifts the rear of a front seat by 1/4" to 1-1/2" to improve sightlines and comfort for compatible Toyota and Lexus trucks and SUVs.

Designed as a compact and durable adjustment kit, this Misakomo spacer set lets you subtly change the angle and height of the driver or front passenger seat without replacing seats or using bulky add-ons. CNC-machined aluminum pieces with a satin black powder coat provide corrosion resistance and consistent fitment for a range of vehicles, including Toyota Tacoma, 4Runner, FJ Cruiser and Lexus GX470 models listed. The package contains six spacers and four bolts to lift one seat; purchasing two sets is required for both front seats.

How will this spacer kit affect driving visibility and posture?

Raising the rear portion of the front seat nudges the seating angle forward, which can open up the driver’s view of the road and dashboards. Small incremental lifts can reduce forward head tilt, easing neck and upper-back strain on longer trips. The change is subtle but often enough to make driving more comfortable without altering airbag or seat safety components.

• Rear seat rise range: approximately 1/4" to 1-1/2"
• Improves forward sightlines over hoods and instrument clusters
• Reduces need to tilt whole seat forward for visibility

What materials and build quality should I expect from Misakomo spacers?

The risers are CNC-machined from solid aluminum for dimensional accuracy and consistent thickness. A satin black powder-coat finish protects the metal from chips and road corrosion while blending with most vehicle interiors. The package includes hardened bolts sized to replace the factory rear seat fasteners for a secure mount.

• CNC-machined aluminum for strength and repeatable fit
• Satin black powder coat for durability and low glare
• Includes four replacement bolts to secure the spacers

How simple is installation, and what tools are needed?

Installation is straightforward and requires basic hand tools: a socket or ratchet set and standard wrenches. Remove the rear seat bolt, loosen the front bolts, position the chosen spacer thickness under the seat bracket, and re-torque the fasteners. Most installs can be completed in under 30 minutes without specialty tools.

• Requires removing one rear bolt and loosening front bolts
• No seat removal or complex trimming needed
• Typical install time: under 30 minutes per seat
