Quick Answer: The Lifetime Mammoth 71799 is the best Lifetime basketball hoop for most driveways — a 50-inch polycarbonate backboard on an in-ground steel pole for $399.99. Want tempered glass without pouring concrete? The Mammoth 90734 is a portable system with a real 54-inch glass board, but it costs $949 — a 137% jump over the 71799 despite sharing the “Mammoth” name. Buyers on a tighter budget should look at the Pro Court 44 ($159.99) or the compact Youth Portable (about $120) instead.

Lifetime is the budget-to-mid-tier name most homeowners already recognize, but its lineup spans five genuinely different products at wildly different prices — and the brand reuses model names across them in a way that trips up anyone shopping by name alone. The “Mammoth” label is the clearest example: it covers an in-ground polycarbonate hoop that costs under $400 and a portable tempered-glass system that costs nearly $1,000, with different warranty terms attached to each. Here’s how all five current tiers actually compare.

1. Mammoth 71799 — Best Overall / Budget In-Ground
Lifetime Mammoth 71799 Basketball Hoop
- A 50-inch shatterproof polycarbonate backboard on a 3-piece, 3.5-inch round steel pole with a friction-weld joint, adjustable 7.5-10 feet via the Action Grip handle in 3-inch increments.
- The cheapest way into a true in-ground system on this site — every other in-ground hoop we've reviewed, Goalrilla included, starts well north of $1,700.
- Backed by Lifetime's standard 5-year limited warranty against manufacturing defects, per Lifetime's own FAQ — not the "lifetime" coverage the Mammoth name implies.
The 71799 is the pick for a permanent driveway setup on a real budget — polycarbonate won’t match tempered glass off the backboard, but it also won’t shatter under a hard rim-hang the way glass can. Setting the pole before the hoop ships? Try Amazon Prime free for 30 days and get the concrete mix, a net, and a level delivered in two days. The tradeoff versus the Mammoth 90734 below is rebound feel, not durability — polycarbonate flexes on contact instead of rebounding cleanly.
2. Adjustable 54 — Best Full-Size Portable
Lifetime Adjustable 54 Basketball Hoop
- A full 54-inch polycarbonate board on a fillable portable base, height-adjustable via a Power Lift or similar handle mechanism depending on the specific model year.
- Sold under several overlapping model numbers over the years (90600, 91094, 71524 among them) with essentially the same 54-inch polycarbonate spec — check the listing's backboard material, not just the model number, before buying.
- Same 5-year limited warranty as the rest of Lifetime's standard lineup.
The Adjustable 54 gets you regulation-width board coverage without paying for glass or pouring concrete — the right call for a renter or anyone who wants the full 54-inch playing surface without the Mammoth 90734’s near-$1,000 price tag.
3. Mammoth 90734 — Best Tempered Glass Portable
Lifetime Mammoth 90734 Basketball Hoop
- True 3/8-inch tempered glass on a heavy-duty steel frame, adjustable 7.5-10 feet via the Mammoth Lift mechanism, with an 18-inch Slam-It Ultra Rim.
- Rolls on a four-wheel base with a 3.5-inch square pole, and ships with cement anchors for owners who want extra tip resistance without going fully in-ground.
- Confusingly shares the "Mammoth" name with the $399.99 in-ground 71799 above despite being a completely different product — portable instead of in-ground, tempered glass instead of polycarbonate, and roughly 2.4x the price.
If real glass rebound matters more than saving $550, the 90734 is the only Lifetime portable that delivers it — see our backboard material comparison for what that actually changes about how the ball plays off the board. Just don’t assume “Mammoth” alone tells you which hoop you’re buying; the model number does that.
4. Pro Court 44 — Best Value
Lifetime Pro Court 44 Basketball Hoop
- A 44-inch polycarbonate backboard on a 27-gallon fillable Pro Court base, telescoping height adjustment from 7.5 to 10 feet.
- Currently $159.99 at Target, down from a $169.99 list price — the smallest footprint of any full-height adjustable model in Lifetime's lineup.
- A smaller board than the 50-54 inch models above means less rebound margin on off-center shots, a reasonable tradeoff for a driveway with limited width.
The Pro Court 44 is the pick for a narrow driveway or a buyer who just wants a functional hoop without paying for board inches they don’t have room for. It’s also the cheapest full-height adjustable system in Lifetime’s current lineup.
5. Youth Portable — Best Compact/Kids
Lifetime Youth Portable Basketball Hoop
- A 32-inch impact-plastic backboard on a light, fillable base, adjustable roughly 5.5 to 7.5 feet for younger kids.
- Small and light enough to carry indoors or into a garage between uses, unlike every other model on this list.
- Priced anywhere from about $85 to $140 depending on retailer and color at the time of purchase — shop around rather than assuming one fixed price.
Right-sized for a driveway shoot-around with younger kids rather than full-height play — see our best mini basketball hoop guide if an even smaller indoor option is the goal.
Why “Mammoth” isn’t one hoop
Lifetime’s own FAQ states plainly that “most Lifetime Products Basketball Systems have a 5-year limited warranty against manufacturing defects” — no carve-out for Mammoth mentioned on that page, even though several retailers advertise lifetime rim coverage specifically on Lifetime’s higher-end tempered-glass Mammoth systems. Whichever warranty terms actually apply to your specific model, the bigger issue is that “Mammoth” spans at least three distinct products: the $399.99 in-ground 71799 with a polycarbonate board, the $949 portable 90734 with tempered glass, and separate 60- and 72-inch Mammoth Bolt-Down glass systems above that. A shopper searching “Lifetime Mammoth basketball hoop” could land on any of these — always confirm the model number and backboard material on the listing before buying, not just the name on the box.
The bottom line
The Lifetime Mammoth 71799 is the pick for most driveways — $399.99 for a true in-ground system with a 50-inch polycarbonate board. Want tempered-glass rebound without concrete? The Mammoth 90734 is the only Lifetime portable that offers it, for $949. Tighter budget or narrower driveway? The Pro Court 44 covers that at $159.99, and the Youth Portable fits younger kids for around $120. Comparing Lifetime against the premium brands instead?
