This is the original version of our Heavy Duty Trailer Link, the cost of these increased a few years back so we have introduced another listing (V2) for people looking for a cheaper option. As the V1 and V2 don't fit together we have two separate listings, we have kept the more expensive version 1's in stock to allow existing customers to add on to their existing fleet. If you haven't used any of our links before and price is a factor then the V2 might be a better option. I will add that the more expensive V1 in this listing does "feel" more robust, having said that the V2 has had no problems with durability in the years we've ran with them.
