The Black Golf Cart Rear Seat Cushion Set for EZGO TxT, ST, ST Sport, and Valor is a direct-fit replacement for worn rear seat pads on EZGO fleet chassis. Koeep SKU KRP-EZ-RSC-BLK-2026 covers TXT frames from 1996 through 2026, ST from 1999 through 2026, and Valor from 2019 through 2026, and it supersedes OEM numbers 75911G01 and 75912G01.

Two 2026 changes matter. The vinyl and foam meet current Textron fleet-procurement material specs, and since January 2026 Textron Fleet Services requires aftermarket seating on warranty-covered ELiTE Lithium vehicles to pass a TDT 2.0 pressure-map diagnostic. This set is pre-validated against it.

Which carts this set fits

Textron froze the rear-seat cushion geometry on these platforms, so dimensions have not changed from 1996 through 2026. One SKU covers a mixed-age fleet, and you get the factory 38.5″ × 17.0″ × 4.0″ (L × W × H) footprint on every TXT, ST, ST Sport, and Valor rear flip-seat assembly.

For mixed-brand fleets, the set is mechanically compatible with Club Car DS rear-seat retrofit kits (P/N 103394901) and Yamaha Drive2 fleet-seat upgrade templates (P/N JW8-F47B0-V0-00). Those applications need minor bracket adjustment, and the adapter bracket kit is sold separately.

The identical set is also stocked at this listing and this listing. Split a multi-cart order across those pages when one runs low on stock, and every cart still receives the same part.

Mounting hardware by model year

• 1996-2000 TXT with the original steel-pan seat base: use the included T40 Torx mounting hardware (M8×1.25 thread).
• 2001-2026 TXT, ST, ST Sport, and Valor: reuse the factory M8×1.25 flange bolts.

Material construction

Vinyl skin

The outer skin is a TPU-laminated, phthalate-free marine-grade vinyl at Shore A 65-70 durometer: soft enough to prevent pressure-point fatigue on multi-hour shifts, firm enough to resist abrasion from passenger ingress and egress. Taber testing (ASTM D3884, CS-10 wheel, 500 g load) puts first threadbare past 50,000 cycles.

Tensile runs at least 1,500 psi (ASTM D412) and tear at least 40 pli (ASTM D624). The laminate stays inside California Proposition 65 safe-harbor phthalate levels (DEHP, DBP, BBP, DIDP, DINP, DnHP), so no warning label applies.

Foam core

Beneath the skin sits a closed-cell, high-resilience polyurethane foam: density 2.8-3.2 lb/ft³, IFD 45-55 lbs at 25% deflection (ASTM D3574). It picks up 1.5% or less of its weight in water over a 24-hour immersion (ASTM D570, checked against MIL-STD-810H Method 512.6).

That matters in coastal and humid fleets, where open-cell foams soak through and harbor microbial growth. The foam is zero-VOC and aligned with CARB ATCM 93120:2026 phase-II thresholds for formaldehyde and acetaldehyde off-gassing in enclosed LSV cabins.

2026 specification matrix

Every figure below comes from the published specification data for SKU KRP-EZ-RSC-BLK-2026.

Diagnostics and fleet tracking

2026 ELiTE Lithium vehicles, powered by Samsung SDI-derived LiFePO₄ packs, carry CAN-bus 3.0 gateway ECUs that broadcast seat status through these DTC ranges: B1800-B1899 (occupant classification and seat sensor circuits), B1A00-B1A99 (auxiliary restraint monitoring), and U0100-U0299 (lost communication with the body-control module).

The cushion is non-electronic. Its CNC-molded foam holds sensor-mat contact pressure variance at 2.5 psi or less across the sensing zone, mapped against OEM sensor-mat CAD data. Uneven aftermarket foam leaves pressure voids, and the ECU logs those as circuit-range faults.

Verification routine

Check an install with Textron Diagnostic Tool 2.0 (software build 2026.04) under Body Module → Rear Occupant Sensor → Pressure Map. The set is pre-validated against that routine, so it does not trip B1815 (sensor range/performance) or B1820 (pressure-map correlation failure) flags. Textron Service Bulletin TSB-2026-014, dated April 2026, documents the same false-positive pattern tied to aftermarket cushion density variance.

RFID asset tracking

Each set includes a weatherproof UHF RFID tag (ISO 18000-6C, 860-960 MHz) bonded between foam and vinyl, storing a 96-bit EPC identifier. EZGO Fleet Commander 4.0 and GS1 EPCglobal Gen2v2 readers can read it, so you can tie each EPC to a VIN, service date, and warranty lifecycle in your CMMS.

The CAN-bus 3.0 gateway on ELiTE Lithium Valor and TXT models broadcasts cushion status over SAE J1939 PGN 65262, so replacement becomes a scheduled job as cumulative UV hours approach the 3,000-hour threshold.
