Restoring your favorite oversized couch-style towable becomes a breeze with the heavy-duty 4 Rider "Great Big Mable" Style 2 Piece Set Replacement Innertube from TRL Watersports, LLC.
- You receive a precision-matched pair consisting of both the massive main base bladder and the tall backrest insert to ensure a perfect fit within your existing nylon shell.
- These boat tube replacements utilize a specialized high-gauge K80 PVC that prevents the "sinking couch" effect often seen with thinner, generic aftermarket brands.
- This dual-chamber design allows you to maintain independent air pressure in the seat and backrest, providing customized comfort for up to four riders simultaneously.
Don't throw away that perfectly good towable cover, re-use it! TRL Watersports original replacement innertubes are quite simply the strongest in the business. This is a bladder replacement for models like the Sportsstuff® “Great Big Mable”, Airhead® “Pit Stop”, and Gladiator “Great Big Brawler” 4-person towable tubes and contains both the SEAT BASE and BACKREST bladders. We also carry the SEAT BASE and BACKREST bladders separately. Please note the position of the inflation valve in the picture and ensure it is compatible with your backrest and that it will align properly! This contains the innertube only, and NOT the cover. Breathe new life into your towable! Don't spoil that summer vacation by having your favorite towable "fall flat"! Have an affordable spare with you on your well-deserved time off! Heavy Duty PVC Construction (12-15% thicker than any original or replacement tube on the market). Double-welded seams for added durability. Super speed valve for easy inflation and deflation. Measurements (Inflated) Approximately 92"L 106"W. If you have any questions on whether this innertube will fit your towable, we will be happy to assist and ensure it is compatible with your cover!
