What the 2026 EZGO Rear Seat Cushion Set Fits

The rear bench is the first thing that wears out on a work cart. The Black Golf Cart Rear Seat Cushion Set for EZGO TxT, ST, ST Sport & Valor replaces worn OEM cushions across the whole TXT platform — model years 1996 through 2026 — with a no-drill, bolt-in fit.

This is a 2026-focused part. It meets the interior durability and material thresholds that NEV/LSV builds carry under FMVSS 500, and it matches the standards cited in current Textron service bulletins out of Augusta, GA. One SKU covers fleet carts and personal carts alike.

Fitment at a glance:

• EZGO TXT, 1996–2026 — direct fit, with pre-molded mounting holes matching OEM seat kits.
• EZGO ST and ST Sport — same TXT mounting pattern.
• EZGO Valor, 2019–2026 — all trims, including the MY26 Valor 4 PTV with its 48V AC drive and rear leaf-spring suspension.
• Fleet and personal-use configurations — consistent fitment across every TXT-derivative model.

Material Standards: Vinyl, Foam, and Burn Rate

Marine-Grade Vinyl Tested to SAE J2412 (2024 Revision)

The outer skin is a multi-layer marine-grade vinyl composite, UV-stabilized and validated under SAE J2412 Cycle A xenon-arc protocols. It resists UV-C degradation at exposure levels beyond 2,500 kJ/m² — a threshold 40% above generic aftermarket alternatives.

Fade resistance is measured, not advertised. After 1,500 hours of xenon exposure, the black UV-stable pigment holds a ΔE color shift of 3.0 or less. In Florida-equivalent UV conditions that means no perceptible fading for a minimum of 3–4 years. Hindered amine light stabilizers (HALS) at 0.5% concentration do the heavy lifting here — OEM TXT cushions from 2014–2020 production runs started surface crazing near 800 kJ/m².

2.2 lb/ft³ High-Resilience Foam Core

Underneath sits a closed-cell, high-resilience polyurethane blend at 2.2 lb/ft³ density, with an indentation load deflection (ILD) of 33–38 lbs. That range balances compression resistance against long-haul comfort — firm enough to keep its shape, soft enough for a full day of seated hours.

The pairing also fixes a known OEM failure mode. Textron TSB-2023-014 documented foam-to-vinyl adhesive breakdown on 2018–2023 OEM TXT cushions, which led to delamination. Foam density and ILD values in this set align with ASTM D3574 and ISO 2439 test protocols.

Flammability and NEV/LSV Builds

The foam core passes the FMVSS 302 horizontal burn test at ≤102 mm/min, and the vinyl also meets ISO 3795. Those are the interior material standards required by 2026 OEM service bulletins from Textron Specialized Vehicles — and they make the set suitable for FMVSS 500-compliant NEV/LSV builds.

DTC Mapping: A Passive Seat That Stays Silent

A rear cushion is a passive interior component with no embedded electronics, so it cannot generate diagnostic trouble codes on its own. It has been validated as non-interfering with body control modules (BCM) reporting in the B0XXX and U0XXX ranges.

It also stays clear of passive occupant detection systems (PODS) and seat-pressure mat circuits. That is what blocks the spurious B1022 and B0081-series codes you can pick up when retrofitting fleet carts.

• B1022 — passenger occupant sensor
• B0081 — passenger presence system
• U0140 — lost communication with BCM

Fleet technicians doing seat swaps should still clear any existing BCM DTCs post-installation with a CAN-bus 3.0-compatible scan tool, then run a BCM re-learn cycle per Textron procedure TP-2026-042.

One real-world case matters. If a 2026 Valor EX1 gas model shows B1022 right after you install this set, look elsewhere — the rear cushion itself cannot trigger body DTCs. Inspect the front passenger seat occupancy sensor harness under the front bucket, especially the yellow SRS connector at pin 3. Corrosion at the BCM connector (C2280B, pin 7) has been documented on MY26 units per Textron TSB-2026-008.

Mounting: OEM Seats and Aftermarket Flip Kits

Direct OEM Replacement

Multiple pre-molded mounting bosses match OEM seat kits for TXT, 1996–2026, so installation stays no-drill, with stainless steel hardware included. Dimensions track OEM TXT Rear Seat Kit Rev. H, and the material certifications sit at parity with Textron OEM part numbers 606129 (TXT rear seat bottom) and 606130 (TXT rear backrest) for 2026 model year applications.

Aftermarket Flip-Seat Compatibility

The boss pattern also covers most major aftermarket rear seat kits — GTW Mach 3, MADJAX Genesis 300, and Steeleng heavy-duty flip-seat assemblies. Hole spacing is standardized at 6.75″ center-to-center longitudinally and 31.5″ laterally, matching both OEM EZGO rear seat brackets and the industry-standard aftermarket drilling template. Check your kit's bolt pattern against the cushion's molded recesses before final torque-down.

Fleet Duty Cycle and Service Life

The 2.2 lb/ft³ high-resilience foam core is rated for a 5-year commercial duty cycle under normal fleet rotation — roughly 3,000 to 4,000 seated hours annually. That exceeds the 3-year OEM fleet cushion replacement interval in Textron Fleet Maintenance Schedule FM-2026, so each cart goes longer between seat swaps.

Abrasion holds up too. The marine-grade vinyl clears more than 5,000 cycles on the Taber CS-10 test at a 1,000 g load before surface breakthrough — well above the 2,500-cycle threshold used for commercial golf course applications.

Procurement gets the simplest win: TXT, ST, ST Sport, and Valor share identical rear seat mounting dimensions, because the Valor rides the TXT-heritage steel frame and rear leaf-spring suspension geometry. One SKU covers three decades of production, and the 2026 model year introduces no changes to TXT-platform rear seat dimensions.

Finish the Interior

A new rear bench next to a tired front seat looks half-done. On an RXV, the Black Golf Cart Front Cushion Seat Cover for EZGO RXV refreshes the front bench in the same black look. On a TXT-platform cart, the Black Golf Cart Front Cushion Seat Cover for EZGO TXT pairs with the rear set for one consistent interior.
