Short answer: replace EZGO leaf springs when the spring pack is cracked, badly sagged, deformed, or no longer supports the vehicle evenly. Upgrade to a heavier spring pack only when the cart regularly carries added rear-seat or cargo load and the exact kit matches the model, year, and gas/electric configuration.
Do not buy a spring simply because a listing says “EZGO.” TXT, Medalist, RXV, Express, and older models do not all use the same rear suspension. This guide focuses on common TXT/Medalist replacement and upgrade scenarios.
Signs your EZGO leaf springs need attention
- The rear of the cart sits visibly lower on one side.
- The spring pack has a cracked or separated leaf.
- The cart bottoms out more easily after adding passengers or cargo.
- Bushings and sleeves are badly worn and the spring eyes move excessively.
- The rear tires rub after adding a rear seat because the suspension is overloaded.
Standard vs heavy-duty leaf springs
A standard spring pack is usually the better choice for a lightly loaded stock cart because it preserves ride comfort. A 4-leaf heavy-duty pack can make sense for a cart with a rear seat, cargo box, larger battery weight, or regular passenger load, but it can also make an unloaded cart ride firmer.
Current EZGO leaf-spring options worth comparing

10L0L 4-leaf rear spring kit for common TXT applications
This heavy-duty style is aimed at common TXT fitment and includes bushings/sleeves. Use it as an upgrade example only after confirming your exact cart year and suspension.
10L0L 3-leaf TXT/Medalist spring kit
A 3-leaf replacement is closer to a moderate-duty configuration and can be a better match when you are replacing worn springs without intentionally stiffening the rear suspension.
Cartalia heavy-duty 4-leaf spring kit
This is another heavy-load option for comparison. Confirm the listing’s gas/electric and year notes because EZGO rear-suspension details changed across generations.
TXT and Medalist fitment is not one simple year range
Aftermarket listings commonly group TXT and Medalist together, but gas and electric fitment can use different cutoffs. Use the serial/model information on the cart and compare it with the seller’s exact application notes. If the cart has already been modified, measure the existing springs rather than relying on appearance.
Replace bushings and hardware at the same time?
If spring-eye bushings, sleeves, U-bolts, or mounting hardware are worn or corroded, replacing only the spring can leave play or noise in the suspension. Inspect the complete mounting system while the spring is unloaded.
Rear seats change the suspension decision
A rear flip seat adds both static weight and passenger load behind the original seating area. If your cart has a rear seat, inspect the springs, shackles, tires, and frame mounting points together. A heavy-duty spring does not increase the manufacturer’s vehicle load rating by itself.
Installation and alignment checks
Support the cart safely before removing spring hardware. After installation, verify the axle sits evenly, U-bolts are tightened correctly, brake cables and wiring are not stretched, and the cart sits level. Recheck hardware after the first short period of use if the spring manufacturer recommends it.
Leaf springs vs lift kits
Heavy-duty leaf springs are not a substitute for a properly engineered lift kit. A spring upgrade can restore ride height under added rear load, but it does not automatically create the steering geometry or front suspension clearance needed for large tires. If your goal is larger wheels and tires, compare our EZGO TXT lift-kit guide before choosing suspension parts.
Replace springs in pairs?
If one rear spring has failed from age or fatigue, replacing both sides as a matched pair is often the cleaner approach because spring rate and ride height can differ between an old and new spring. Inspect shackles, bushings, U-bolts, and axle locating points on both sides at the same time.
Bottom line
Choose EZGO leaf springs by exact model and load, not simply by spring count. Standard or 3-leaf replacements are usually better for stock/light-duty use, while 4-leaf heavy-duty springs can help carts that consistently carry rear passengers or cargo. Fitment and overall vehicle load limits still come first.
