EZGO RXV upgrades: what fits, what it costs, what to do first

The EZGO RXV has been built since 2008 and the aftermarket treats it as its own cart, separate from the TXT it is sold alongside, because below the seat it is one. Independent front suspension, a 48V AC drive on the electric, an electric park brake instead of a pedal lock, a shallower battery bay and a different rear body mean that lift kits, rear seats, windshields, light kits and battery trays are all RXV-specific. If you own one, buy RXV parts and nothing else, and read the two sections below on lithium and the park brake before you do anything electrical. The EZGO page in the parts-by-make guides explains how to read the plate and tell an RXV from a TXT; the fitment finder confirms the year.

The RXV as a platform

EZGO launched the RXV for 2008 with an AC induction motor and controller, which was new in golf carts at the time. The electric version has been 48V throughout, with four 12V flooded batteries from the factory. EZGO also sells a six-battery tray for the RXV and some owners have switched to six 8V, so count yours before you shop. The electric park brake is a motor brake that sets automatically when the cart stops and releases when you accelerate; there is no pedal to lock. Gas RXVs run a Kawasaki engine and take every body accessory here.

From about 2017 EZGO sold the RXV ELiTE with a factory lithium pack built on Samsung SDI cells, and the Liberty four-seater (2021 on) is a factory lithium cart on the RXV platform. Both take RXV body accessories and neither needs a battery conversion. The nose was restyled around 2016, which is why light kits are often listed in two runs; confirm on the sticker on the frame rail under the seat back.

Why TXT parts do not fit

Owners come to the RXV from a TXT or from TXT-centered forums and assume EZGO parts are EZGO parts. They are not. The TXT has a solid front axle on leaf springs; the RXV has A-arms on coil springs, so a TXT lift kit has nothing to bolt to. The TXT rear body is a flat deck with a bumper the rear seat kits hang from; the RXV rear is shaped differently and the seat kits are built for it. The windshield struts are spaced differently. The battery bay is shallower. The dash is a different shape. The only things that cross over are roof-strut accessories like sound bars and some mirrors, and wheels, because every golf cart maker uses the 4-on-4 bolt pattern.

The upgrades, in order

1. Windshield, about $100 to $200

A windshield for the EZGO RXV clamps to the RXV struts, fits 2008 to present, and takes twenty minutes. Folding acrylic is the common pick.

2. Light kit, about $150 to $400

A light kit for the EZGO RXV drops into the molded recesses in the RXV nose. Kits are often sold for 2008 to 2015 and 2016 and later because of the restyle; confirm on the plate. Buy the version with turn signals, horn and brake lights if the cart may ever be street legal; the street-legal page for an EZGO RXV lists what else is needed. The electric RXV needs a 48V-to-12V reducer, which the better kits include.

3. Rear flip seat, about $350 to $850

An RXV-specific rear seat kit for the EZGO RXV fits 2008 to present and folds flat into a cargo deck. Budget for an extended top or top extension to cover it.

4. Lift kit, wheels and tires, about $1,000 to $1,900 all in

An RXV lift kit is about $450 to $750 for a 6-inch spindle kit, a little more than the TXT kit because it works with the A-arms. Then wheels and tires for an RXV, usually 10-inch wheels and 22x11-10 tires, add about $500 to $1,100. The AC drive handles the bigger tires better than a DC cart does, but you still lose some range.

5. Steering wheel, floor mat and dash, about $80 to $300

A steering wheel for an EZGO RXV needs the RXV adapter, which is not the TXT adapter. Mats, dash kits and cup holders for an RXV are molded to the RXV dash.

6. Sound bar, about $150 to $500

A sound bar for an EZGO RXV clamps to the roof struts and is one of the few parts shared with the TXT. It runs off the same 12V reducer the lights use; size it at 30A or more for both.

7. Lithium battery, about $1,500 to $2,500

Covered in its own section below, because the RXV has a catch the Precedent and TXT do not.

8. Controller, about $600 to $1,500

The RXV AC drive is a different animal from the DC systems on a TXT or Precedent, and the plug-in speed controller market for it is smaller. Navitas sells an AC kit for the RXV that raises top speed to the low twenties; EZGO dealers can also change speed settings on some years. How to make an EZGO RXV faster puts the options in order. Do not fit a TXT controller to an RXV under any circumstances.

9. Enclosure, about $150 to $600

An enclosure for an EZGO RXV is RXV-specific and sold by top length; measure after the rear seat goes on.

10. Upgraded seats, about $200 to $800

Replacement seats for an EZGO RXV and covers are RXV-specific because the seat is more contoured than the TXT bench.

Lithium on an RXV: the tray depth

The RXV battery bay is shallower than a TXT or Club Car Precedent bay. A 48V 105Ah pack that drops into a Precedent with inches to spare can sit too tall under an RXV seat, or foul the seat frame. This is the single most common complaint from RXV owners who bought a pack listed as fitting “any 48V cart.”

Three ways around it. Buy a pack sold with an RXV-specific tray kit; Eco Battery and Epoch both list one, and the kit is built to the bay. Buy one of the lower-profile packs that owners report clearing the RXV seat, which is where the RoyPow in the picks comes from. Or run four 12V lithium batteries in the stock battery positions, which sit where the lead-acid did and never touch the seat. In every case, measure your bay height and compare it to the pack height in the listing before you order. The 48V lithium page covers the packs and the battery buying guides cover the lead-acid versus lithium decision; the battery calculator runs the cost.

Use the charger that ships with the pack. The RXV factory charger is a lead-acid charger with the round 48V EZGO plug, and the lithium charger uses the same plug, so the swap is painless. ELiTE and Liberty carts already have lithium; leave their packs alone.

The park brake quirks

The electric RXV park brake surprises every new owner at least once. It sets itself when the cart stops and you lift off the accelerator, and it releases when you press the pedal. There is no pedal lock. If the cart is parked on a hill with the key off, it stays put on its own.

To push the cart, go to the run-tow switch under the seat and set it to Tow. That releases the brake. Pushing an RXV in Run, or towing it in Run, fights the motor brake and can damage the drive system, and EZGO’s manual is explicit about it. If the pack is completely flat, the brake may not release at all; charging for a few minutes first usually solves it, and the owner’s manual covers moving a cart with a dead pack. Read that section before you need it.

Two more. The electric RXV beeps when the key is on and the cart is in Tow, which is a reminder, not a fault. And a cart that will not move when you press the pedal but hums is usually in Tow or has a pedal switch fault, not a dead motor; check the switch before calling a shop. Owners on the electric RXV report the park brake itself is reliable; it is the habits from a TXT that cause trouble.

Other platforms

The Club Car Precedent upgrades page is the sister page to this one. If you are weighing an RXV against a TXT on the used market, the EZGO page has both, and the Club Car page and Yamaha page cover the other makes.
