Wheels & Specifications
What size socket removes my lug nuts?
A 19mm or 3/4″ socket will remove your lug nuts.
What is the wheel bolt pattern and stud thread?
The Mammoth bolt pattern is 4×100. Lug stud thread is a standard 1/2×20.
What is the torque specification for my lug nuts?
Lug nuts should be torqued to 55–65 ft-lbs, tightened in the proper sequence.
Warranty
Is my windshield covered under warranty?
Yes — the windshield is covered if the issue is a manufacturing defect. It is not covered if it has been misused, abused, struck by an outside source, or shows excessive wear from normal use.
Are my batteries covered under warranty?
Yes. Our lithium batteries — produced by the same manufacturer that produces Tesla batteries — are covered for ten years. Lead-acid batteries are covered for one year.
Exclusions include lack of maintenance, regularly undercharging the cart, and battery failure caused by a third-party electrical source or wiring. Tampering with the charger or charger algorithms voids battery coverage.
Will MammothEV pay to have my cart delivered for repairs?
No. Expenses incurred transporting the vehicle to and from a MammothEV service center — or an authorized service center, technician, or designee — are the sole responsibility of the cart owner unless otherwise noted by the service provider or seller.
However, our dealer-offered warranty covers all labor costs and transportation fees. Contact your local dealer for details.
Will adding accessories void my warranty?
No. Accessories are welcomed and encouraged. An accessory only becomes a warranty issue if it directly relates to the failed component. All accessories should be installed by a trained professional.
