Essential Specs and 2026 Compliance at a Glance

The Black Golf Cart Rear Seat Cushion Set is a direct-fit replacement for the EZGO TxT, ST, ST Sport, and Valor model families, covering model years 1996 through 2026. If your flip-seat vinyl is cracked, sagging, or flaking, this set mounts to the same points as the OEM cushion it replaces.

It meets updated FMVSS 302 flammability resistance requirements with a horizontal burn rate ≤102 mm/min, and it uses SAE J369-referenced automotive-grade vinyl rated at 650+ hours of UV exposure. Both numbers matter once you register the cart as a street-legal LSV.

• Foam core: high-resilience polyurethane at 2.0 lb density with a 35 ILD firmness index — the industry sweet spot for rear passenger comfort and long-term sag resistance.
• Mounting: multiple molded holes on the backside accept OEM EZGO rear seat kits (P/N 10114371G04 and variants) plus MadJax Genesis 250, GTW, and Steeleng aftermarket frames.
• Electronics: fully passive, no electronic integration — compatible with all CAN-bus 2.0/3.0 architectures, including the 2026 Liberty 4F and Express 6 with updated BMS firmware.
• Service life: projected 2026–2030 five-year cycle, aligned with the EZGO MY2027–2030 refresh window.

Material Engineering: 2026 Stock vs. Pre-2024 Cushions

The vinyl substrate is a UV-stabilized polymer matrix with integral cool-touch reflective pigment in a classic black, matte-satin finish, cold-crack rated to −23°C (−9.4°F). It is a direct answer to the passive thermal management trend visible in the 2026 EZGO Liberty series.

Benchmarking follows OEM-grade material specifications drawn from Tesla Cybertruck interior textiles, Ford Bronco Sport marine vinyl, and Toyota bZ4X cabin material standards. It also matches the aftermarket's May 2026 convergence on marine-grade polymer composites for outdoor durability.

Phase-Change Foam Technology

Microencapsulated phase-change materials (PCMs) in the high-density polyurethane core regulate seat surface temperature, cutting peak heat absorption by up to 25% versus conventional black vinyl. That is the difference you feel on a sun-exposed rear-facing seat in July.

Hydrolytic Stability

The foam meets ASTM D3574 wet-set compression criteria and resists moisture-induced degradation in humid environments — the spec that keeps a Valor cushion from going soft and lumpy in coastal or tropical operation.

Anti-Microbial Vinyl Topcoat

The topcoat conforms to ISO 22196:2026 antimicrobial surface standards, inhibiting bacterial and fungal colonization on high-touch surfaces. Resort and golf-course fleets increasingly demand this on carts shared by dozens of riders a day.

Technical Specification Matrix

DTC Codes: Why a Cushion Shows Up in Diagnostics

The set is a passive mechanical component — no embedded sensors, no wiring. But it interfaces with the rear flip-seat frame, and on 2026 EZGO models that frame sits adjacent to the battery compartment and BMS monitoring circuits. If you scan a 2026 RXV Elite Lithium or Express L6 platform after a seat install, know these ranges:

• P0A00–P0A7F: Battery Pack & BMS communication faults — inspect rear seat mounting bolts for protrusion into the battery tray area.
• U0100–U0299: Lost communication DTCs — make sure the install does not pinch the CAN-bus harness routed along the rear frame rail.
• C0040–C0047: EV powertrain control module faults — relevant for 2026 CARB Advanced Clean Cars II-compliant vehicles with standardized diagnostic architecture.

Installation Clearances That Prevent Fault Codes

On 2026 RXV Elite Lithium models with the Samsung SDI battery pack, the BMS communication harness routes along the rear frame crossmember, directly beneath the seat mounting points. A bolt over 25 mm of penetration can compress or pierce the harness loom, triggering intermittent U0100 (Lost Communication with ECM/PCM) and P0A7F (Battery Pack Degradation) codes.

Verify bolt length first. Cap penetration at 25 mm, hold ≥10 mm of clearance from all wiring harnesses, and reference EZGO Service Bulletin SB-2026-014 for rear frame harness routing updates on MY2026 RXV Elite and Express L6 platforms. The multiple molded hole pattern gives you flexible bolt placement to steer clear of harness routing zones.

Fitment: Models, Frames, and the One Exception

The set covers EZGO TxT, ST, ST Sport, and Valor from 1996 through 2026, plus the RXV with select flip-seat kits. The multi-pattern molded mounting holes are what make that range possible.

• OEM cross-reference: EZGO P/N 10114371G04 and variants
• MadJax Genesis 250
• GTW Gusto flip-seat
• Steeleng TXT-RS-001
• 10L0L universal rear seat kit

The exception is the 2026 Liberty 4F. Its forward-facing bucket-style rear seat is a fundamentally different architecture, so this flip-seat set does not fit it. Everything else with a flip seat is covered: the 2026 Express 6 rear-facing bench configuration, the ST Sport 2+2, and all flip-seat-equipped Valor and TxT variants through MY2026.

LSV Street Legality in 2026

Under 2026 FMVSS 500 LSV regulations, FMVSS 302 interior flammability compliance is mandatory for street-legal operation in all 50 states. Swapping worn or non-compliant rear cushions for this certified set protects your registration eligibility.

Florida, Arizona, and California increased roadside compliance checks starting Q2 2026, inspecting seat integrity and material certification on registered LSVs. Plan for the inspection, not the excuse.

SKU, Service Life, and Model-Cycle Alignment

SKU KOEEP-RSC-BLK-EZGO-TXT carries a projected 2026–2030 service life — a five-year cycle synchronized with the EZGO refresh through MY2027 (Liberty 4F, Express 6) and the anticipated MY2028–2030 Valor and ST Sport platform updates.

The mounting system works in both directions: backward compatible with pre-2026 frames, forward adaptable to announced 2027+ rear seat frame geometries. Buy once, carry it through the refresh cycle.
