Meritor Straight Truck Spindle
Our Meritor Straight Truck replacement spindle is crafted to meet the unrelenting demands of straight truck applications. Built with high-grade, industry-standard 1040 unalloyed steel, it offers unmatched strength and durability. This straight truck spindle benefits from a unique induction heat treatment process, ensuring superior resilience under heavy load conditions.
Meritor axles are the industry standard in heavy-duty trucking, accounting for approximately 70% of Class 8 truck axles in North America. These axles are widely used in Freightliner, Western Star, Volvo, Mack, Kenworth, and Peterbilt trucks, making our Meritor-compatible spindle an essential repair solution for fleet owners and independent operators alike.
Your package includes the spindle and a sleeve. Please note that the tools required for installation are not included. For a complete list of the required tools, refer to the “Required Tools” section below.

Description
Meritor axles are known for their durability and longevity. The average lifespan of a Meritor axle, when properly maintained, can range from 500,000 to over 1,000,000 miles! However, their lifespan can be cut short by improper maintenance, harsh road conditions, and overloading that can lead to broken or damaged spindles.

The average straight truck axle can cost $3,000 – $8,000 plus installation fees, and can take 6-10 hours for an experienced technician to install. That is a significant investment of resources, and while some trucks are worth it, there is a better way. Our meritor straight truck spindles save you a lot of both time and money and are engineered to out-perform the original parts.
Unlike a full axle replacement, our Meritor Straight Truck Replacement Spindles are designed for quick and efficient installation, typically taking only 90 minutes instead of an entire day. This means you save on parts and labor costs, getting your truck back on the road faster to maximize productivity and your investment.
