2026 EZGO rear seat cushion set: what it is and what fits

If the rear bench on your TXT, ST, ST Sport, or Valor is torn, flat, or mildewed, the Black Golf Cart Rear Seat Cushion Set For EZGO TxT, ST, ST Sport, Valor models is a direct-fit, dual-cushion replacement. It bolts to the TXT-heritage platform without frame modification and covers everything from the entry Valor 48V AC-drive PTV up to the ST Sport.

The timing matters. E-Z-GO is moving its Model Year 2026–2027 lineup toward AC drivetrains and lithium-ready architectures, per the MY2027 Liberty and Valor S+ announcements. This set holds backward and forward compatibility across the TXT, ST, ST Sport, and Valor families through that transition.

Fitment across TXT, ST, ST Sport, and Valor

Coverage runs from the 1996 TXT through the 2026 model year, plus ST, ST Sport, and Valor (2023–2026). The 2026 Valor is a 4-passenger PTV with a 114.7" overall length and 47.0" width, and it uses the same rear seat geometry as the TXT platform. One set covers all four nameplates.

Bolt pattern and flip-seat kits

The back plate carries multiple molded mounting holes. These line up with the three dominant aftermarket flip-seat bracket patterns: Gusto™, MadJax Genesis 250, and the Nomad series. You can bolt the set to an OEM EZGO rear frame or to the most common aftermarket kits.

Dimensions match the Nomad/Gusto industry footprint: seat bottom 38.19" × 14.17" (970 × 360 mm), backrest 37.0" × 16.5" (940 × 419 mm).

ST Sport cargo beds and brake clearance

On ST and ST Sport trims the set works with the factory flip-seat cargo bed mechanism. Flip the seat down and the backrest cushion stays mounted, clearing the 40.5" × 35" cargo platform these systems use.

One note for 2026 ST Sport models with the upgraded 4-wheel hydraulic disc brake package: keep the seat frame mounting bolts clear of the rear brake lines. A 0.25" clearance is recommended.

Materials: 28-oz vinyl over closed-cell foam

The vinyl skin

The outer skin is 28-oz UV-stabilized marine-grade vinyl, the weight class OEM suppliers use for factory TXT and Valor trims. It resists cracking from -20°F to 140°F (-29°C to 60°C). That range matters in the Sun Belt LSV markets of California, Arizona, Florida, and Texas, where 2026 Valor registrations are projected to rise 18% year over year.

It meets ABYC H-31 marine upholstery benchmarks: at least 1,000 hours of QUV accelerated weathering (ASTM G154) and tear strength of at least 45 lbf (ASTM D624 Die C), with tensile checked per ASTM D412.

The foam core

Inside is closed-cell polyurethane foam at 2.8–3.2 lb/ft³, aligned with ABYC H-31 seating standards for moisture resistance and compression recovery. Water absorption tests at less than 3% weight gain after 24-hour submersion (ASTM D1056, Grade 2B2), and compression set stays under 10% at 50% deflection (ASTM D3574).

Budget cushions typically use open-cell foam that soaks up water, collapses, and grows mildew. Closed-cell construction is what lets fleet carts in coastal or humid regions run longer service intervals.

Against the 2026 OEM Valor cushion

The OEM part ships with roughly 24-oz vinyl and standard open-cell foam. Against it you get a 28-oz skin (about 17% thicker, with stronger UV inhibitors), closed-cell foam, and a multi-pattern back plate that fits more aftermarket frames than the single-pattern OEM plate.

CAN-bus, DTC codes, and the Curtis controller

The cushion set is a purely passive mechanical assembly with zero electronic integration. Nothing talks to the CAN-bus, the Curtis 1268 or 1234SE motor controller, or any ECU. The 2026 Valor's 48V AC system (Samsung SDI lithium compatible) needs no controller recalibration after a seat swap, and the set is compatible with every EZGO TXT-platform CAN-bus architecture.

Curtis fault codes after seat service

A seat job puts your hands near the Curtis 1268 (DC SepEx) or 1234SE (AC induction) controller. If a code appears after reassembly, the cause is disturbed wiring in the harness. Reference the Curtis 1,X through 4,X ranges and start with these common post-service codes:

• 1,2: throttle fault. Verify throttle pot wiring integrity.
• 2,1: low battery voltage. Confirm the 48V pack was not drained during service with accessories running.
• 3,4: field winding fault. Check F1/F2 motor terminals if rear body panels came off for bracket access.
• 2,4: main contactor coil open. Verify solenoid wiring near the controller, easy to disturb when reaching rear seat mounts.

Service life and replacement planning

Projected lifecycle is 5–7 years (2026–2031/2033) under normal outdoor exposure, roughly 30% longer than a standard OEM cushion. The projection draws on the vinyl's UV inhibitor half-life of about 2,500 hours of direct sun, the foam's compression set resistance, and accelerated weathering data from equivalent marine upholstery applications.

Budget the swap at the 5-year mark for commercial duty (daily use, full sun) and at 7 years for personal carts with covered storage. SKU BGC-3734 stays compatible with all EZGO TXT-platform models through the 2030 model year, per the TXT-heritage strategy in E-Z-GO's MY2027 announcements.

Keeping the vinyl alive

Clean with pH-neutral marine vinyl cleaners only, in the pH 6–8 range. Bleach and alcohol products strip plasticizers and start the cracking cycle. In desert sun, black vinyl surfaces can pass 160°F, so covered storage slows heat and UV damage. Material failure under normal use falls under the 1-year KOEEP warranty.

Cross-references and LSV notes

The set directly replaces EZGO OEM rear seat cushion part numbers across TXT (1996–2026), ST, ST Sport, and Valor platforms, and is functionally equivalent to the aftermarket references OCPTY B08MVM49HR and ILVGOLF B09WHTQHRL.

For LSV conversions: FMVSS 500 governs active safety equipment (seat belts, glazing, lighting), and this passive cushion introduces no non-compliant materials. The flame-rated foam core and marine-grade vinyl suit an LSV interior, and FMVSS-mandated rear seat belt assemblies install without interference. Durability tracks SAE J2358 expectations for occupant contact surfaces.

The front bench takes a different part, and KOEEP carries a separate Black Golf Cart Front Cushion Seat Cover For EZGO TXT for that job. The same rear set also sits on a dedicated catalog page for EZGO TxT, ST, ST Sport, and Valor models, the wider parts range lives in the Interior Auto Parts collection, and the complete guide to this rear seat cushion set covers ordering and installation in depth.
