Reese Hitch Extender for 2" Trailer Hitches - 14" Long - RP11003

Average Customer Rating:  4.8 out of 5 stars   (6 Customer Reviews)

Extend your trailer hitch receiver opening so that you can clear your spare tire when using your hitch-mounted bike rack or so that your trailer won't hit a rear-mounted propane tank when you make sharp turns.

- RP11003

I needed this to give a complete turning clearance for my car hauler trailer and it works great. Would highly recommend it.

- RP11003

Easy process of ordering, and product works great.

- RP11003

The extension seem very sturdy and should function fine. However, it will not fit into my hitch adapter without grinding the corners of the solid bar. The corners are too square and need to be rounded off a bit. That's way only 4 stars. Haven't got to use it yet. Got it for towing my Samurai behind my truck camper.

- RP11003

This hitch extender is exactly what we needed to accommodate our new bike rack and still be able to tow our boat. Great match up for our specific needs.

- RP11003

Extender looks to be extremely well built. Fits my hitch perfectly.

Ask the Experts about this Reese Hitch Adapters

  • How Much Does Hitch Extension Reduce Capacity of Hitch Really?
    It is easy to see where the confusion comes in because the answer is all of the above. The reduction in capacity depends on how big the hitch is and what the manufacturer specifies, so it can be anywhere between 25% and 50%. You may be able to use the 14" Reese Hitch Extender # RP11003, which, when used with a weight distribution system, is rated for a maximum tongue weight of 650 lbs and max trailer weight of 6,500 lbs. However, it will reduce the overall capacity of your hitch by 35...

  • Trailer Hitch Extender for Use with a Tow Dolly
    We do have extenders that you can use to tow a trailer or tow dolly but many extenders are designed for flat towing a vehicle with 4 wheels on the ground and not for use with a tow dolly. Reese extender # RP11003 is rated for 4,000 pounds gross trailer weight and 400 pounds tongue weight but none that can be used to tow a trailer are rated as high as the Blue Ox extension. The other option is to use a longer ball mount than what you have now in order to get more space between the...

  • Recommended Hitch Extension for 2004 Ford F-350 with Camper Towing 7100 lbs Travel Trailer
    If you need 12 inches to clear your camper, you might be interested in the MaxxTow # MT70024. This hitch extender will give you 12 inches of clearance from your current pin hole location. Please not that using a hitch extender will decrease the weight capacity of your trailer hitch by 50 percent. It sounds like your vehicle has a weight capacity of 15000 lbs, and a tongue weight of 1500 which would be well within your weight limit even with the reduced capacity using the hitch extender....

  • Recommended Trailer Hitch and/or Extension for 2017 GMC Sierra 2500 with Service Body
    For your 2017 GMC 2500, the service body issue isn't solved with just a hitch swap. Instead you will need a long ball mount like # 80232 or a hitch extender for the additional clearance needed. The addition of a hitch extender will reduce your hitch capacity by 50% unless you are using the Torklift Supertruss system. If you have a heavy trailer, I recommend using the TorkLift SuperHitch Original Trailer Hitch Receiver - Custom Fit - Class V - Dual 2" Receivers # TLC1211 which is...

  • Is There a Hitch Extender that Can be Used with 3,800 lb Trailer
    Reese has a couple hitch extenders for 2 inch that have 4,000 lb capacities that you could use like the # RP11003 which is 14 inches long or the # RP11004 which is 18 inches long. As long as the hitch on your 2006 Toyota Tundra has a capacity that is twice the weight of your trailer this would work fine since hitch extenders cut the capacity of the hitch they are installed in by 50 percent.

  • Trailer Hitch Extender For Weight Distribution So Tailgate Can Be Opened
    We do have hitch extenders that will work with a 2-inch trailer htich receiver. There are tongue weight and trailer weight ratings for the extenders you need to pay close attention to. For a 7-inch extension I recommend part # HE06. With weight distribution, this limits th gross trailer weight to 7,000-lbs and tongue weight at 700-lbs. For a 14-inch extender I recommend part # RP11003. The gross trailer weight with this extender is 6,500-lbs and 650-lbs tongue weight. We also offer...

  • Can a 12 Extender be Used to Tow a 3,000 lb Trailer with a Class A Motorhome
    Any 12" extender that would fit your application will reduce your overall hitch weight capacity. The Reese Hitch Extender # RP11003 (14") will reduce it by 35% while most others will reduce it by 50%. Options like the Curt Hitch Extension and Reducer # C45048 that you referenced are meant to fit a 2-1/2" hitch receiver and are typically used for a pickup with a camper in the bed. If your trailer hitch and Class A are rated high enough you will be able to tow your trailer and car with...
