Toptow trailer hitch extender adapter – 6in drop/rise
If you need to level a trailer, clear a low rear bumper or gain a bit more reach from your towball, the TOPTOW 6in drop/rise hitch extender is a tidy, no-nonsense solution. It’s built tough, easy to fit and made to work with the common 2in receiver setup — none of the faff, just practical kit that does the job.
key features
- Industry-standard 2in x 2in receiver and 2in shank – accepts ball mounts, bike racks, cargo carriers and most other tow accessories.
- 6in drop or rise – flip it to suit, so you can level your trailer or get clearance under a low bumper.
- Two usable extension lengths (8.5in and 10.5in measured from shank pin hole to receiver pin hole) – handy for avoiding bumper interference and giving flexible positioning.
- Strong towing capacity – 7,500 lb gross towing weight with 350 lb tongue weight, suitable for many trailers, small boats and campers.
- Built to last – 5/8in pin holes, a matte-black powder coat finish and an anti-rattle bolt to cut down movement and road noise.

why this helps
If your trailer nose is sitting high or the towbar is scraping the bumper, this gives a quick, sensible fix — it levels the load, improves handling and reduces stress on the tow vehicle. If a bike rack or cargo carrier is too close to the tailgate, the longer position stops rubbing and keeps access clear. The anti-rattle bolt is a small but welcome touch, so you’ll get less clatter on rough roads. And because it’s the standard 2in size, it plays nicely with the wide range of existing accessories — no need to swap gear about.
typical use cases
- Levelling a caravan or trailer for safer towing and steadier handling on long runs.
- Creating clearance between a tow accessory and a low rear bumper or tailgate.
- Giving extra reach for bike racks or cargo carriers so doors can still open.
- Temporary use when swapping vehicles or accessories without changing the existing ball mount.
A couple of practical notes: always double-check your vehicle and accessory measurements before buying, especially shank length and how much drop or rise you actually need. If either the receiver or shank isn’t the standard 2in size, this won’t fit. And don’t exceed the 7,500 lb towing or 350 lb tongue weight ratings — pushing past those limits risks damage and is unsafe.
All told, the TOPTOW extender adapter is a sensible bit of kit for anyone who tows regularly and wants flexibility without buying a whole new towbar. It’s simple, robust and does exactly what it says on the tin — which is handy when you’re out on the road.
