I believe you are referencing a replacement shock for an actuator and from what you described it does sound like you are in need of a new one. The correct one will be a replacement for your actuator, and I'll list the replacements we carry so you can select the correct one:

- Replacement Shock for Titan Model 6 and 10 Brake Actuators # T1242600
- Replacement Shock for Titan Model 20 Brake Actuator # T0778400
- Replacement Shock Absorber for Titan Model 60 Brake Actuators # T2336200
- Replacement Shock Absorber Spring Kit for Titan/UFP Brake Actuators # TK71-758-00

Question:

How do I know exactly what type of hitch I have a? Those shock absorbers do look like the cracked ones they have eyeholes on both sides and seem to be about 6 inch long, my boat 1999 searay 270 sundancer is around 7500 to 8000 pounds , it has a 25 ft aluminum trailer , Question is How do you know which shock absorber to recommend if you dont know the Weight of the trailer and boat together?

You would need to know the brake actuator you have in order to get the correct replacement shock, as they are direct replacements for specific models of actuator. For example, the Replacement Shock for Demco Hydraulic Trailer Brake Actuators # DS12426 fits a number of models such as the Demco Hydraulic Brake Actuator - Drum - Zinc - 2-5/16" Ball - 12,500 lbs # DM8101801 which is a model DA10 actuator. A lot of them will have a model number or marking somewhere on the actuator which has information about it such as the manufacturer and model number.

If you can't determine the actual actuator you have, you could always take a chance based on exact measurements; for example, the Demco Replacement Shock is 7" over all in length when collapsed and 9-1/8" when fully opened and it has center eyes with diameters of 0.625" and 0.89". Otherwise, you will need to replace your actuator with the appropriate type. The Demco # DM8101801 I referenced has a 12,000 lb capacity, is for drum brakes, accepts a 2-5/16" hitch ball and mounts to a straight, 3" wide trailer tongue. You would need to match up those things with your specific trailer for a new one.

I have added a link to our entire selection of actuators to check out.
