Average Customer Rating:  4.9 out of 5 stars   (132 Customer Reviews)

This set includes a locking hitch pin and a locking dual pin assembly for your 180 Hitch or Weigh Safe 2-ball mount. Locks are keyed alike for your convenience. The locking hitch pin helps deter theft of your ball mount.


This set includes the main hitch pin for the truck receiver and the height adjusting dual pin. It is well engineered and includes all weather covers to protect the locks from the elements. Would highly recommend this product to complement the 180 hitch.


After a year of usage I've been very happy with the hitch pin and the single key for the Weigh Safe lock.


My old locking hitch pin was showing some wear after 12 years of use, so I ordered the WS06 because I wanted to have both parts of the hitch keyed alike instead of having two different keys. I emailed etrailer because the description didn't specify that it fit my hitch, but Kaylyn R. responded in 30 minutes, at 7:30 PM in the evening, that it would fit perfectly on my Weigh Safe WS10-2 10" drop hitch. I placed the order and received it in 3 days. It fits and functions perfectly. This is only my second order with etrailer, and I won't go anywhere else for towing components. The customer service is second to none.
I love my hitch setup, and the WS06 is the cherry on top of the sundae. Thanks again for your fast shipping and customer service.


This is my second purchase of the Weigh Safe hitch. I had to buy a smaller one because I traded trucks and the 3" shaft was too large for the new truck's receiver. The first one I had was used around 3 years and I was 100% satisfied with it so it was an easy decision for this purchase.


Purchased this for my 2016 Yukon Xl Denali. I've got a 2.25"front/1" rear level so that made a high receiver even higher. Costly? Yes. But this thing gives me the option to tow pretty much anything (within the respective weight limits) that I want. The box that it comes in fits perfectly in the compartment under the floor in the storage area, so it's always on the ready. This is exactly what I wanted.


Nice polish on the stainless. Stays clean and wipes down easily after miles of road grime.

Barely looks like its had any use after a year on the road. Stainless is the way to go.

Very pleased with the quality of the Weigh Safe product. Having the dual pin and the hitch pin keyed alike just makes everything easier.


WS06 Locking dual pin and hitch pin for TB4-2 Weigh Safe 180 hitch and 2-ball mount. WS06 and TB4-2 ordered together, well made, quality products, that enhance the towing ability of my trucks. Easily adjusted for correct towing height, safely locked in place providing additional security for hitch and trailer.


Super nice locking pins. Smooth operation thanks for your great support


The perfect accessory to my 180 Hitch! The added security of theft deterrent will help me sleep a little better when the hitch is left in the truck.

So far so good! Locks still work well even after a year of use. I occasionally spray a dry lube in them which should help them last a lifetime.

Worked exactly as designed. About to buy another Weigh Safe hitch! I love 'em!


Awesome Hitch. Would recommend to anyone. It works just like it says it should and on top of that it looks great with the aluminum and stainless.


The locks have smooth action and I like not having to worry about loosing the little cotter pins that come with the original hitch pins.

The lock is holding up a year later, I lost the dust cover a while ago.

Locking pins work great , and I feel good that my trailer hitch is locked down I don’t have to worry about people stealing it

Still working good flips easily and turns to the back to stay out of the way of your legs

This Weigh Safe TB4-2 ball mount has worked flawlessly. I pull two different trailers and each one requires a different ball height. Problem is solved with this hitch. Just pull the pin and adjust the ball height to the desired position. I also purchased the locking keyed-alike hitch pin and ball pin. This is convenient in only requiring one key.


Great to have a single key to change ball & remove hitch
Works great


Great customer service and communication from etrailer
Thanks Michelle S.!

The Lock Dual Pin Assembly and Hitch Pin work well.

Being an Engineering Project manager/Mechanical designer/ and Machinist my standards are high :-).
Poor Job of de-burring after the machining of key tumbler assembly receptor hole on 180 Ball Mount.

The lock assembly would not seat fully until burr was de-burred/chamfered and cleaned up on the 180 Ball Mount mating hole to the dual pin lock.

So far with limited use .. this is why I give 4 stars instead of 5.


Haven't pulled with it yet , just got it last night ....But it looks amazing and the quality is Superb! This thing is so nice I want to drive around with it and show it off in traffic !


Ball, hitch, and locking pin fit perfectly on my 2016 Ram 1500. The machining is superb. The design offers many options for different trailer hitch heights. I like how it can be installed with the ball under the receiver when not in use... out of the way, but secure. I opted for the keyed-alike pins which conveniently eliminates having to keep track of multiple keys. Very satisfied.


Sure is nice to have both locks keyed the same not to mention the quality workmanship put into the hitch and locking mechanisms.++++++A

I all I can say is it is flawless. Great product. Give it 5 stars.

Extremely high quality product and service! You won't be dissapointed!


Easily one of the prettiest ball mounts I've ever had. This kit included a locking dual pin, which made the purchase of the separate locking dual pin an unnecessary expense, so I guess I now have a spare, but otherwise everything was as advertised.

I was hoping that I could flip the ball mount and reverse it under the receiver, and I can, but only in the lowest set of holes. The low profile socket head fastener that goes into the piston assembly for the gauge contacts the reinforcing ring on the receiver hitch just before the 5/8" pin can be installed...I may relieve the reinforcing ring slightly (less than 1/32") to gain the 1" of ground clearance in this configuration when not towing.


This design is exceptional and having both the Weigh Safe system keyed alike to the hitch pin means not having to search for the right key! But you should know that the Weigh Safe hitch system already comes with a locking hitch for the ball height adjustment that is keyed different from the WS06 keyed alike, meaning the original lock is no longer needed, but I'll keep it as a backup.


I am giving this product a 4 star right now only because I haven't hooked up to it yet. Loving the look and the design so far. I did upgrade to the locking pin set and am happy that it is a 1 key for both design. Easy operations to change the sizing around.

5 Star for sure after a year of use. Still works just as easy to adjust as the day I bought it. Absolutely love how easy it is to change the hight as to pulling many trailer options
B.Rad - 03/07/2019


I have been using this lock set for about 1 year. Although I do not leave the the hitch on my truck full time, I do leave it in for days or weeks at a time. I no longer worry about the hitch being stolen when I forget to take it out. The locks are secure and work as expected. I would recommend removing both lock assemblies periodically and cleaning and lubricating them to keep them working smoothly.
