2026 Compliance Snapshot

NEV and LSV interior parts face updated requirements for the 2026 model year, and this set was engineered against them. The core facts, in four lines:

• Fire safety: FMVSS 302 and ISO 3795 certified, burn rate <100 mm/min, per NHTSA 2026 updated LSV interior compliance and 2026 Textron OEM service bulletins.
• UV durability: SAE J2412 tested — color shift stays under ΔE 3.0 after 1000 xenon-arc hours. A 3-year pro-rated UV warranty is included.
• Electronics: passive and electrically inert. Verified zero DTC injection on MY2024–2026 ELiTE and S4 Express controllers, and on 2018–2023 TXT 72V carts.
• Fitment: shared rear seat pan geometry across TXT (1996+), ST, ST Sport, and Valor (2019+) — a single SKU covers every application.

Material Deep-Dive: Skin, Foam, and Thread

Top skin — 28 oz/yd² marine-grade expanded vinyl

The wear surface is 28 oz/yd² marine-grade expanded vinyl with TiO₂ (titanium dioxide) UV-reflective pigment dispersed through the film — a formulation aligned with Textron OEM material spec TSV-24-008 for 2026 Class A surface durability. SAE J2412 xenon-arc testing holds color shift under ΔE 3.0 at 1000 hours, and the 3-year pro-rated UV warranty backs that number for sunbelt fleets.

Foam core — 2.2 lb/ft³ high-resilience polyurethane

Beneath the skin sits a closed-cell 2.2 lb/ft³ HR (high-resilience) polyurethane core, compression-molded to 44±2 Shore A durometer. In ASTM D3574 static fatigue cycling, permanent set stays under 6% after 22h @ 70°C — the cushion springs back instead of flattening under daily fleet use.

Seam thread — Tex 90 bonded polyester

Seams use UV-inhibited bonded polyester thread, Tex 90, 3-ply, with a minimum break strength of 11.5 kgf. Weak thread tears out long before the vinyl wears through, which matters on high-cycle fleet carts exceeding 1,200 passenger loads per season.

Technical Specification Matrix

Every value below is the published spec for this set, in one place for fleet procurement files and audit paperwork.

DTC Mapping: What This Set Can and Cannot Trigger

On 2024+ lithium-ion EZGO ELiTE models, CAN-bus 3.0 body control module integration logs rear seat accessory recognition digitally. So does swapping cushions flag codes? No. Passive seat assemblies generate no bus traffic — this set shows verified zero DTC injection on MY2024–2026 ELiTE and S4 Express controllers.

Heated seat circuit — B1A35-13 and B1A35-11

ELiTE lithium models with optional dealer-installed heated rear seat pads flag body DTC B1A35-13 (Seat Heater Circuit — Open) when the heating element connector goes open-circuit; a short to ground flags B1A35-11. This cushion contains no electronics, so it triggers neither code.

Retrofitting a cart that had heated seats? Disconnect the heating element harness first, then clear the BCM DTC memory with the EZGO Freedom Diagnostic Tool or an equivalent OBD-II CAN reader.

Rear belt interlock — B0078-11 and B0078-13

Fleet-spec ELiTE models with the optional rear seat belt interlocks (fleet safety package FS-03) can throw B0078-11 (Rear Passenger Seat Belt Sensor — Circuit Short to Ground) or B0078-13 when the rear buckle switch circuit opens or shorts. Those codes are unrelated to cushion replacement. If one appears after seat work, inspect the 2-pin buckle sensor connector under the rear seat pan for disconnection or debris ingress.

Fitment: TXT, ST, ST Sport, and Valor Share One Pan

The Valor (2019–2026) shares the identical rear seat pan stamping and mounting geometry as the TXT platform. Factory and dealer-installed flip-seat kits — EZGO part no. 75626Gx — take the same cushion dimensions regardless of trim:

• Bottom cushion: 38.5" W × 18" D
• Backrest cushion: 38.5" W × 16.5" H

The Koeep Black Rear Seat Cushion Set drops straight onto the factory pan — no adapter brackets required. Cross-reference: EZGO rear cushion assemblies 75626G01, 75626G02, and 75626G03, plus Textron Service Kit SK-REAR-CUSH-26. The covering SKU is EZ-RSC-BLK-26.

Want the front bench to match the rear? Koeep lists a black front cushion seat cover for the EZGO TXT and a matching front cushion seat cover for the EZGO RXV. For the wider cabin lineup across cars and bikes, browse the full interior parts collection.

Built for 2026 Fleet Procurement

Manufacturing runs under ISO 9001:2015 quality management with full batch traceability — the paper trail that 2026 fleet audit requirements lean on. Projected service life is 2026–2030, a 5-year fleet duty cycle at more than 1,200 loads per season.

The regulatory backdrop is shifting too. Ford, GM, Toyota, and Tesla don't build golf carts, but Tesla's influence on CAN-bus architecture standards, plus the GM/Toyota push for unified EV subsystem diagnostics under the SAE J1979-3 (2026 draft), pulls aftermarket parts for Textron EZGO, Club Car, and Yamaha fleets toward the same material traceability expectations as passenger EV interiors.
