A Direct-Fit Rear Bench Rebuild for the EZGO TXT Platform

If the rear bench on your E-Z-GO is cracked, sagging, or sun-bleached, the Black Golf Cart Rear Seat Cushion Set for EZGO TXT, ST, ST Sport & Valor Models swaps in as a complete unit — bottom cushion and back cushion, no bracket adaptation. It is a direct-fit, OEM-grade replacement for the Textron E-Z-GO TXT platform lineage, model years 1996–2026, including ST, ST Sport, and Valor trims.

The set is dimensionally matched to flip-style rear seat kits from GTW, MadJax, and DoubleTake, plus factory E-Z-GO rear seat assemblies. For 2026, Textron's Augusta, GA facility builds the Valor on its TXT-heritage platform alongside the enhanced RXV — this cushion set tracks that platform, including the 48V AC-drive Valor 4.

Fitment: Model Years and Seat Kits Covered

The verified ranges: EZGO TXT 1996–2026, ST 1999–2026, ST Sport 2004–2026, Valor 2019–2026. That spans the Textron Specialized Vehicles light-transport lineup through the current production cycle. Factory rear seats and flip kits from the three major brands all line up with the molded mounting holes — no drilling.

KOEEP also lists this identical set on two alternate catalog pages: listing one and listing two. One exclusion: the 2026–2027 E-Z-GO Liberty 4F runs four forward-facing seats and a different rear architecture — this bench-style set does not fit it.

Material Architecture: Vinyl, Foam, and the Numbers

Marine-Grade Vinyl Outer Shell

The upholstery is a 4-way stretch marine-grade vinyl with UV-inhibitor pigments and antimicrobial additives. Economy vinyl typically cracks within 18–24 months of sun exposure. This shell is validated under SAE J2412 Cycle A: 3,500 kJ/m² total radiant exposure through a xenon-arc apparatus, daylight-filtered irradiance at 0.55 W/m² @ 340 nm.

In real terms, that equates to roughly 5–8 years of Florida or California sun without color shift beyond ΔE 3.0. Cool-touch reflective pigment technology cuts surface temperature by 12–18°F versus standard black marine vinyl in direct midday sun — you notice it the first time you sit down in July.

High-Resilience Polyurethane Foam Core

The foam runs 2.2 lb/ft³ against the 1.8 lb/ft³ used in most OEM E-Z-GO cushions. Compression set stays under 10% after 22-hour ASTM D3574 testing, so the cushion holds its shape under repeated passenger loading. The seat bottom is 3 inches thick versus the 2.5-inch factory baseline — a half inch more comfort that still clears flip-seat folding mechanisms.

2026 Technical Specifications

Torque Specs and the DTC Question

This is a passive assembly — no CAN-bus, no sensors. Installation still matters on 2019+ Valor and RXV models with 48V AC-drive Curtis controllers: loose or poorly seated cushions create mechanical vibration that can trigger false throttle sensor correlation faults (EZGO PDS Code 1-2 / 3-2) or body controller mounting-stress anomalies.

Torque to OEM specification: M8 bolts to 18–22 ft-lbs, M10 bolts to 28–32 ft-lbs. On flip-seat retrofits, all 8 cushion mounting bolts get 22 ft-lbs. The TXT-heritage rear leaf-spring suspension feeds road vibration straight through the seat frame, so under-torqued bolts rattle — and the rattle reads like an electronic fault.

Indirect DTC Crosswalk for 48V AC-Drive Models

• PDS Code 1-2 (Throttle Sensor Correlation): vibration at the APPS mount.
• PDS Code 4-3 (Motor Stall / Mechanical Obstruction): sympathetic resonance from loose body hardware.
• Curtis Fault 31/32 (EMC interference): metallic seat-frame grounding anomalies.

The 2026 Valor runs a Curtis 1234SE controller. After installation, clear stored codes and run the 3-cycle key-on diagnostic self-test in the 2026 E-Z-GO service manual, Section 5.2.3. If a code returns, re-check bolt torque before replacing sensors.

Service Life, Warranty, and OEM Cross-Reference

Rated life is 5–8 years under normal golf-course and PTV duty, with UV-degradation resistance extending through the 2030 model year. Materials are phthalate-free and California Proposition 65 compliant for interior NEV/LSV use.

Cross-reference codes: OEM E-Z-GO 607248 (TXT rear bottom) and 607249 (TXT rear back), plus GTW 01-230/01-231 series, MadJax MJ-300 series, and DoubleTake DT-Rear-TXT-BK. Order by those numbers and you get the same footprint every time.

KOEEP backs the set with a 1-year warranty and free worldwide shipping on orders over $99. Fleet buyers can price volume orders on the request-for-quote page.

Care Routine for High-Sun Climates

The vinyl ships with SAE J2412-validated UV inhibitors. Carts parked outdoors in 300+ sunny-day regions — Phoenix, Las Vegas, South Florida — still benefit from a 90-day routine:

• Apply 303 Aerospace Protectant (SPF 40 equivalent for vinyl) every 90 days.
• Cover the cart with a breathable cover. Non-breathable covers trap condensation and accelerate hydrolytic degradation of the polyurethane foam.
• Skip petroleum-based cleaners such as Armor All and WD-40 — they strip UV inhibitors and speed plasticizer migration.
