What the 2026 EZGO Rear Seat Cushion Set Covers

The Black Golf Cart Rear Seat Cushion Set (SKU 2375) replaces worn rear upholstery on EZGO TXT (1996 and newer), ST, ST Sport, and Valor models. You get a seat bottom and a seat back cut to the TXT-heritage flip-seat footprint. Brackets are not included, because the cushions drop straight onto OEM and aftermarket rear flip-seat frames.

The set is passive. It works with every 2026 drivetrain in the family: 48V AC-drive, DC series-wound, and the ELiTE lithium platform with CAN-bus 3.0 diagnostics. It needs no wiring and no coding.

Koeep rates it backward- and forward-compatible across TXT-heritage frames through model year 2030. One check for newer carts: the 2027 Liberty 4F brings a redesigned rear passenger compartment that may need updated cushion dimensions.

Model coverage

• EZGO TXT, 1996 and newer
• ST and ST Sport utility models
• Valor PTV, built on the same TXT-heritage steel frame with identical rear seat geometry
• MPT and RXV carts running rear flip-seat kits: MadJax Genesis, GTW Mach Series, SGC Carolina, or OEM E-Z-GO Titan X

Vinyl and Foam: What You Get

0.8mm marine vinyl with HALS and benzotriazole

The topcoat is 0.8mm marine-grade vinyl carrying hindered amine light stabilizers (HALS) plus benzotriazole UV absorbers. That is the same dual-action chemistry specified in OEM 2026 E-Z-GO seating for the Liberty 4F and Express S4 trims.

Economy vinyl leans on carbon black pigment alone and starts breaking down within 500–800 sun hours. This set is rated 1,500+ hours under ASTM D4329 Cycle A, about 5–7 years of Sun Belt sun with proper care. CFFA-2 accelerated light aging shows no appreciable color change after 1,500 xenon-arc hours.

Closed-cell XLPE foam instead of open-cell PU

The core is closed-cell crosslinked polyethylene (XLPE) at 2.8 lb/ft³. Open-cell polyurethane, still common in budget cushions, absorbs 0.8–1.2% of its volume in moisture per 24-hour cycle once humidity passes 70%. Over one Florida or Gulf Coast season that leads to foam breakdown, mold (Aspergillus niger per ASTM G21), and seat pan corrosion.

The XLPE core absorbs under 0.05% water by ASTM D2842 and passes CFFA-120 mildew testing with no growth, which matters most on ST and ST Sport carts that see washdowns, fertilizer drift, and coastal salt spray. The polyethylene base panel also avoids the wood-fiber rot common in pre-2020 aftermarket cushions.

Spec Matrix: Koeep Set vs OEM vs Economy

Diagnostics: Which DTCs Apply in 2026

A cushion swap triggers no fault codes on its own. The set has no electronics, so seat sensor flags on heated or cooled luxury trims never point at it, even though 2026 body diagnostics run the B0XXX to B3XXX range under ISO 14229-1 unified diagnostic services.

Torque is where a code can sneak in. Loose rear seat hardware on a CAN-bus 3.0 cart can vibrate enough to log a false U0140 (lost communication with body control module). Under-torqued M8 bolts can also set B0028 (seat position sensor correlation) on Liberty 4F and Express LSV trims with occupant classification modules. Hit 18–22 ft-lbs everywhere and neither fault has a way in.

Installation: Torque, Sequence, Thread Locker

Eight fasteners hold the set: 4 for the seat bottom, 4 for the seat back. Use M8 Grade 8.8 bolts into the TXT rear seat frame inserts and pull each one to 18–22 ft-lbs in a cross pattern.

• On ST Sport models with a rear cargo bed, stow the bed upright before you start, or the cushions can sit misaligned.
• Bolt the seat bottom first: 4 fasteners, cross pattern, 18–22 ft-lbs.
• Bolt the seat back: 4 fasteners, same torque.
• Add thread-locking compound (Loctite Blue 242 or equivalent) on all rear seat bolts for turf, unpaved roads, or other high-vibration use.

Field Problems: Cracks, Mold, RXV Fitment

Valor cushions cracking inside 8 months

E-Z-GO's entry-level Valor ships with cost-optimized seating, so early cracking points to economy vinyl with light UV stabilizer loading. Cracks inside the first 12 months, especially in AZ, FL, TX, and CA, match phthalate plasticizer migration driven by thermal cycling.

The fix is material, not electronics. The Koeep replacement runs HALS-stabilized marine vinyl rated for 1,500+ UV hours, roughly 2 to 3 times the life of the economy stock. On 2026 ELiTE models, also check B1A24 (battery thermal management warning) if extended sun exposure has heated the battery compartment.

Mold control on ST Sport

Turf, landscaping, and farm work put the ST Sport around moisture, fertilizer, and organic debris. Keep to this schedule:

• Weekly: mild soap and water. Skip bleach-based cleaners, they degrade vinyl plasticizers.
• Monthly: marine-grade UV protectant such as 303 Aerospace Protectant, per the ASTM D4329 maintenance guidelines.
• Quarterly: check the cushion undersides for trapped moisture and keep the seat pan drainage holes open. The XLPE core will not wick, but standing water between cushion and pan still grows surface mold.

Will it fit a 2026 RXV?

Yes, with one check first. The RXV takes this set when it runs a flip-seat kit with the standard footprint: MadJax Genesis, GTW Mach Series, or SGC Carolina. Proprietary kits like the DoubleTake Spartan use unique cushion geometries, so check the brand before ordering.

2026 RXV models with the ECOXGEAR IntelliScreen run CAN-bus checks at key-on, so torque the frame bolts to spec before you call the job done.

Cost: OEM P/N 607127 vs the Koeep Set

The 2026 E-Z-GO OEM rear seat cushion set, P/N 607127 for TXT/Valor, retails around $220 to $310 per cushion pair through authorized dealers. The Koeep set matches or beats the material numbers: closed-cell XLPE instead of OEM open-cell polyurethane, 0.8mm marine vinyl instead of the 0.6mm OEM base, at a fraction of the price.

Rated service life is 5–7 years under normal use, defined as under 2,500 annual runtime hours in non-commercial service. The XLPE core holds over 85% of its original loft after 80,000 compression cycles per ASTM D3574. Fleets running 10+ EZGO units feel that in per-unit-year maintenance spend across the 2026–2030 ownership window.

Matching Front Covers and Spares

Rear cushions wear at the same pace as the fronts, so check the driver bench when the back splits. The Black Golf Cart Front Cushion Seat Cover for EZGO TXT covers the front bench in the same deep black, keeping one cabin look instead of patchwork.

Need a spare or a set for a second cart? Koeep also stocks the same rear seat cushion set on its own catalog page, and both items sit in the Interior collection with the rest of the car and motorcycle cabin parts.
