Lippert / KwikeeMade in the USA1-Year WarrantyKwikee 379178 Cotter and Clevis Pin -- Electric RV Step Hardware Replacement

When a worn or broken pin causes your Kwikee electric steps to bind, skip, or fail to retract cleanly, this factory-correct cotter and clevis pin set gets them moving properly again. Sold as a matched pair -- one clevis pin and one cotter pin -- these small but critical fasteners secure the motor and linkage assembly that drives your steps in and out. Made in the USA by Lippert, the parent brand of Kwikee, with a limited 1-year manufacturer warranty.

Stop a Sticking or Misbehaving Step Before It Gets Worse

The clevis pin and cotter pin are the pivot fasteners connecting the electric motor drive to the step linkage arm. Over years of road vibration, moisture exposure, and repeated cycling, these pins wear, corrode, or simply back out -- causing sloppy travel, binding, or a step that won't fully extend or retract. Replacing them is one of the quickest and most affordable fixes in RV step maintenance.

This kit matches OEM specifications for Kwikee electric step systems. The clevis pin runs 1/4" in diameter and 1-7/8" in length. The cotter pin locks it in place at 1-3/8" in length. No drilling, no fabricating -- these are direct drop-in replacements for the original hardware.

Factory-Correct Fit

Matches OEM dimensions exactly: 1/4" x 1-7/8" clevis pin and 1-3/8" cotter pin for proper linkage alignment.

Complete Hardware Set

Includes one clevis pin and one cotter pin -- everything needed to restore the pivot point in one kit.

Made in the USA

Manufactured by Lippert/Kwikee to original equipment standards for consistent fit and durability.

Cross-Reference Ready

Cross-references part number 905205000, making it easy to confirm compatibility with your existing parts list.

Where These Pins Fit in Your Step System

Kwikee electric steps use a scissor-style linkage driven by a small 12V motor and gearbox. The clevis pin passes through a clevis bracket on the motor or actuator arm and aligns with a hole in the linkage. The cotter pin passes through the groove at the end of the clevis pin shaft and bends to lock everything in place. Together they form the primary pivot that translates motor rotation into step extension and retraction.

If your steps are chattering, hesitating, or you can physically wiggle the linkage arm side-to-side at the motor connection, these pins are the most likely cause and the first thing to inspect.

Quick Diagnosis Tip: With the steps extended, gently push and pull the linkage arm laterally. Noticeable play at the motor-to-linkage joint almost always means the clevis or cotter pin has worn through or fallen out entirely. Inspect before assuming the motor is the problem -- a missing cotter pin is a five-minute fix.

Compatible Step Systems

These pins are designed for Kwikee electric step systems manufactured by Lippert. Kwikee steps are found on a wide range of Class A, Class C, and fifth-wheel RVs from manufacturers including Coachmen, Forest River, Fleetwood, Jayco, Keystone, and many others. If your steps carry a Kwikee or Lippert brand label, this hardware kit is the correct factory replacement.

Cross-Reference: This part is also listed under part number 905205000. If you have that number on your existing hardware or a service invoice, this is the same pin set.

Installation Notes

Replacing these pins requires basic hand tools -- typically a pair of needle-nose pliers to remove the old bent cotter pin, a punch or small hammer to tap out the clevis pin if it has corroded in place, and pliers to bend the new cotter pin tabs after installation. Always disconnect shore power or disable the step controller before working in the linkage area to prevent accidental step actuation during the repair.

Maintenance Tip: After installing new pins, apply a light coat of marine-grade grease or white lithium grease to the clevis pin shaft before inserting it. This helps prevent corrosion from trapping the pin and makes future service much easier. Re-inspect the cotter pin bend after the first 50 to 100 step cycles to confirm it has not worked loose.

Important Information
  • Always disconnect power to the step controller or shore power before servicing the step linkage. Accidental actuation can cause injury.
  • This kit includes only the cotter pin and clevis pin. Motor, gearbox, linkage arms, step treads, and mounting hardware are sold separately.
  • Inspect the clevis bracket and linkage arm holes for elongation or cracking before installing new pins. Worn bracket holes will cause premature pin failure even with new hardware.
  • The cotter pin must be bent fully open after insertion to prevent backing out. Do not reuse a previously bent cotter pin.
  • Confirm your specific step model number before ordering if you are unsure of compatibility. Kwikee step series vary and not all use the same hardware dimensions.
