Exact part that I needed for my 24yo boat trailer. I wanted to replace my old parts with the exact part that came with the trailer. I could have bought knock-off parts from another site but didn't trust the quality or the sizes that was offered. etrailer had what I wanted. Quick shipment too. Kept me informed of the process of my order.



by:

Works just fine! Just can't tighten the bolt as tight as humanly possible or it won't allow the roller to turn. Use a nylon nut and/or put a tack weld on the nut and you're good to go.

This bow roller fit perfect on my shorelander trailer winch. They call it a 4 inch wide roller and was wondering if it would fit but when I received it I measured and it was 3-3/4 inches wide and fit perfect. It only took about 4-5 days to receive it. Great place to order parts.

  • What is the Largest Diameter 4 Inch Bow Roller for Boat Trailer Available
    Currently the CE Smith Bow Roller for Boat Trailers - PVC - 4" Long - 1/2" Shaft - Amber # CE29543 is the largest diameter roller we carry at 3-3/4 inches. The Yates Bow Roller for Boat Trailers - Heavy-Duty Rubber - 4" Long - 1/2" Shaft # YR4174-4 is the next largest at 3-1/2 inches and the other options are 3-1/4 inches in diameter. I've linked the page to all your options to assist.

  • Bow Roller Recommendation to Replace a Bow Stop on a 1986 Eagle Trailer
    The Yates 4 Inch Bow Roller, # YR4174-4, is designed to be used with a 4 inch wide mounting bracket. The roller itself actually measures 3-7/8 inches long so it can fit in a 4 inch space and roll. This roller should work great on your 1986 Eagle trailer. A small gap between the roller and the bracket is ideal to allow the roller to rotate freely. A 3 inch roller would not stay centered with the boat hull when loading as well as the 4 inch roller would.

  • Replacement Bow Roller Brackets for Boat Trailer
    While we don't have any specific replacements for your boat trailer we do have bow roller brackets that you may be able to use. For example, the CE Smith Bow Roller Bracket # CE31005PG with the Yates Bow Roller for Boat Trailers - Heavy-Duty Rubber # YR4174-4 and Roller Shaft with Pal Nuts for Boat Trailer Rollers # CE10700A. I have added links to video reviews of these parts as well as links to our entire selection of brackets for you to look through.

  • Replacement Bow Roller for 5/8 inch Shaft
    I have a few different options for you. The Rubber Endcap # YR134-5 that you mentioned can be used with keel rollers, spool rollers, or bow rollers. If you are wanting to stick with a bow roller, We do have a Bow Roller Assembly # YR450B-400B available that comes with a 1/2 inch shaft. This will eliminate the need to find a bow roller with a bigger shaft hole. I did go out to the warehouse to see with it was possibly that a 5/8 inch shank could fit in a bow roller that has a 1/2 inch hole...

  • Replacement Option for 3-1/2" Rubber Bow Roller
    The closest thing we have to a 3-1/2" long bow roller is the # YR450BLK. This is 3-3/4" long x 3-1/4" diameter and made of thermal-plasticized rubber. If you don't want the thermal-plasticized rubber we have the # YR4174-4 which measures 3-7/8" long x 3-1/2" diameter. Both of these are made for a 4" wide bracket with a 1/2" diameter shaft.

  • 3 inch Boat Roller Availability
    We sell 3 inch bow rollers like the part # YR300Y that is designed to attach to a 1/4 inch stud. Or for a 3-3/4 inch one you would want part # 804 or # YR4174-4.

  • Recommendation for Replacement Bow Stop Roller Measuring 4 Inches with 1/2 Inch Hole
    Hey Craig, thanks for your recent order with etrailer.com. We really appreciate your business. I have a couple different options that would work for you. Yates offers the thermoplastic rubber bow roller in yellow, # YR450Y, and blue, # YR450B. The thermoplastic rubber material is stronger and softer than the standard polyurethane rollers and it won't leave marks on your boat. These rollers measure 3-3/4 inches long and are made to be used in 4 inch wide brackets with 1/2 inch diameter...
