This is an optional RPM Heavy Duty 3.5mm Rod End Set. RPM has been known for exceptionally strong, tight-tolerance rod ends (also known as “ball cups”) for many years. They have been known as some of the strongest and highest quality rod ends in the R/C industry for over 20 years! Standard RPM rod ends have always been quite versatile, but the use of 3.5mm turnbuckles has become very popular. Since the RPM standard rod ends have too small of a hole for the larger turnbuckle to thread into properly, they decided to release these 3.5mm Heavy Duty Rod Ends that allow the use of larger than stock 3.5mm turnbuckles while still using a standard 4.3mm (.170”) diameter ball stud, that is common to most 1/10th scale Losi, Associated and some HPI vehicles. Now anyone can run a stronger 3.5mm turnbuckle size without having to sacrifice strength or durability with an inferior rod end!

RPM 3.5mm Heavy Duty Rod Ends are molded in a light gray color, sold in sets of 12 per package and are factory-backed by the industry-leading RPM lifetime warranty.

NOTE: RPM 3.5mm Heavy Duty Rod Ends are designed for use with 3.5mm (.137”) diameter turnbuckles and 4.3mm (.170”) diameter ball studs. They will not work with oversized ball studs such as HPI’s 4.8mm versions.
