## Overview

The AtoZ Fabrication Tire Carrier Hinge Kit (Mega Spindle) is engineered for tire carriers accommodating 33" to 37" tires. Made from US-sourced 4130 chromoly steel, this kit features CNC-machined surfaces for enhanced welding and rigidity. With a robust 1.5" spindle diameter, it outperforms standard spindles, making it the ideal choice for off-road enthusiasts looking to upgrade their vehicle's capabilities.

## Description

Making your own tire carrier? This is for you. The AtoZ Fabrication tire carrier hinge is the most used kit on the market. The standard spindles are good for up to 31" tires while the Mega Spindle is designed for larger tires or if you plan on putting accessories on your swing-away! The spindles fit into a hole you drill in your bumper, 1.25" for the standard spindle and 1.5" for the Mega spindle. This kit include all bearings, races, seals, and hardware needed for installation. Once you weld the spindle into your bumper and weld the 4" tall, 2.25" OD hinge tube onto your tire carrier you have a well sealed and very strong assembly. These can also be used for any fabrication project you have that needs a heavy duty pivot - there are hundreds of creative ways to utilize these kits. There is no warranty or liability implied on this product as we cannot control how it is used or installed. If you have a heavy tire/wheel combo or are adding options to your swing away then we highly recommend an upgrade to our Mega Spindle! All Mega Spindles are manufactured from 4140 Chromoly steel for un-matched strength! Kit includes 1 spindle (standard duty or mega duty), 1 CNC-Machined outer hinger tube (2.25" OD and 4" tall), 2 tapered roller bearing sets (1 upper and 1 lower), 1 bottom lip seal, 1 upper cap seal, 1 assembly hardware kit (washer, castle nut, cotter pin). BENEFITS OF THE MEGA-DUTY HINGE KIT: 1.5" spindle main diameter compared to 1.25" for standard spindles, 80% stronger w/ greater weld surface, US-sourced high grade 4130 chromoly steel with CNC-machined surfaces for better welding and carrier rigidity, Longer weld area to fit a 5" tall bumper, Weld both top and bottom machined radius to relieve stress risers.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Medium duty swing away hinge, great value!
*by T***. on May 3, 2024*

Solid steel shaft, precision machining (for a snug bearing fit) tapered angular contact roller bearings, seal and dust cap all fit perfectly. The zerk (grease nipple) is a great touch to keep water out and hinge operating smoothly for years. Great value for the DIY’er building a swing away tire carrier

### ⭐⭐⭐⭐⭐ Very stout, good quality, USA made!
*by N***D on October 30, 2018*

I bought the Mega spindle as I will be using it in building a tire carrier bumper that will be carrying a 35” tire, 3 gallon gas can, & maybe a hiLift jack so I wanted something that will hold up to the abuse. The primary selling point for this one over others was that the shaft is made of chromoly steel which is far more durable. When I received it, I was plesently surprised that the races were already pressed into the barrel.The only thing I wish it had was a spot for a grease zerk. However, there may be some customers that would prefer not having one, it is a product that could fit many needs. A hole could easily be drilled and taped to screw in a zerk if desired. Be sure to install the correct order. Check out YouTube videos if needed, unfortunately no instructions are given with the product. However, if you’re buying this item you are probably mechanically inclined enough to figure it out. Great USA made product!!👍
