The catch
Out of stock at Lifetime on November 12, 2026, with delivery "not available". The warranty is not stated on the product page, Lifetime's spec table shows an 18 inch "backboard offset" next to the 51 inch figure in the feature list, and Lifetime says this model is made in its own plant in China.
Key specs
| Board | 72" glass |
|---|---|
| Pole | 6" x 6" |
| Overhang | 51 in |
| Height | 7.5 to 10 ft |
| Warranty | Not stated |
Installation
The Lifetime Mammoth 72 bolts to an anchor kit set in concrete. Lifetime gives the hole size and concrete in the manual for this model; check it before you buy bags. Let the concrete finish curing before you mount the hoop, and call 811 before you dig.
Warranty
Lifetime does not state the warranty on this product page; ask before you buy.
The Lifetime Mammoth 72, in three lines
The Mammoth 72 is the cheapest way into a full 72 by 42 inch tempered glass board in our comparison: $1,749.99 at Lifetime on November 12, 2026, on a one-piece 6 inch square pole with Lifetime's Anti-Flex anchoring.
Its Mammoth Pump moves the rim from 7.5 to 10 ft with one hand and no trigger, and Lifetime lists a 51 inch offset from pole to backboard in its feature list.
The catch: it was out of stock at Lifetime the day we checked, and the product page does not state the warranty, which costs it points in our formula.
Who it's for
Buy it if
- You want a big glass board and your budget tops out under $1,800
- You like the idea of a pump handle instead of a crank
- You can wait for a restock or find it at a store
Skip it if
- You want to order today
- You want the warranty in writing before you buy (ask Lifetime first)
- You care about where it is made
The price is the story
Every other 72-inch hoop we compare costs $2,399 or more. The Mammoth gets you the same 72 by 42 inch board size and a 6 inch pole for $1,749.99. That is why it ranks eighth overall despite the missing warranty: price counts for 20% of our score, and the board and pole score well. On our 72-inch ranking it comes fifth of five, mostly because the warranty is not published.
The Mammoth Pump
Instead of a crank, Lifetime uses a hydraulic, triggerless single-hand adjustment. In its own Q&A Lifetime describes it as squeezing and slowly pulling the handle. Range is 7.5 to 10 ft, like the Goalrilla line. The Slam-It Ultra rim is 5/8 inch solid steel.
Before you buy
Ask Lifetime two things: the warranty terms in writing and the restock date. If you need a hoop this season, the Goalrilla GS72C ($2,399.95) is in stock with a lifetime warranty that covers the glass. We compare the Mammoth with Spalding's in-ground hoop in Lifetime vs Spalding.

- One-piece 6" square pole on an Anti-Flex anchor
