Question:

I ordered the 54980 Reese High Performance Trunnion Head and Shank Product. Which I believe is the 58167 Head. My existing Reese Bars are 800 lb Spring Bars, 10,000 Max Gross Wt. 800 Hitch Wt. the Trunnions have 22210 D stamped on them. They look like Replacement Trunnion 58098. My problem is do these fit together? The size of the Trunnions seam a bit small for the Head. Would Trunnion 58097 for high weight bars fit better?

Expert Reply:

Yes the Reese High Performance Trunnion Head with Shank, # RP54980, comes with the, # RP58167, trunnion head.

You are going to need to measure the bar thickness you have. The earlier bars were 1-1/8 inches and the later bars are 1-3/8 inches. You mention the 22210D that is stamped on your trunnions. That is the casting number which does not pertain to the part numbers, so I would not worry about the casting numbers.

The Reese Replacement Trunnion and Pin, # 58098, uses a spring bar thickness of 1-1/8 inches and is for 600 lbs. and 800 lbs. spring bars.

The Reese Replacement Trunnion and Pin, # 58097, uses a spring bar thickness of 1-3/8 inches and is for 1,200 lbs. and 1,700 lbs. spring bars.

So if the spring bar you have measures 1-1/8 inches the Reese Replacement Trunnion and Pin, # 58098, will work. If the spring bar measures 1-3/8 inches you can use the Reese Replacement Trunnion and Pin, # 58097.
