Why Onshoring Spacers & Lock Plates Is Gaining Momentum

Heavy-duty truck manufacturers have recognized that overseas component sourcing creates unacceptable operational risks. Supply chain disruptions have forced a fundamental reassessment of procurement strategies, with spacers and lock plates becoming focal points for domestic production initiatives.

Global supply chain disruptions and rising costs

Extended international supply networks have proven unreliable for critical truck components. Shipping costs increased 77% between January 2021 and August 2022. Manufacturing labor costs rose 6.2% to USD 42.00 per hour during early 2022. These cost pressures have made overseas sourcing increasingly uneconomical for precision components.

Tariff implementations have created additional cost burdens for manufacturers. A 25% tariff on imported medium- and heavy-duty trucks took effect November 1. Industry analysts project total cost impacts of 15-24% on Class 8 trucks and 16-18% on dry van and reefer trailers. Manufacturers face tariff expenses on individual imported components even when final assembly occurs domestically.

OEM demand for faster, local sourcing

OEMs now require suppliers who can deliver spacers and lock plates within two weeks rather than traditional overseas timeframes. Production schedules cannot accommodate extended lead times that characterize international sourcing. Local suppliers provide the response speed necessary to maintain assembly line operations during supply chain uncertainty.

The strategic value of domestic production

Foreign direct investment in U.S. manufacturing reached USD 121.00 billion during 2021, representing 36% of total foreign investment. This capital flow reflects recognition that domestic production offers strategic advantages beyond immediate cost considerations.

Lock plate manufacturers benefit from vertical integration opportunities available through domestic operations. American suppliers can deliver improved tolerances and high-volume production capabilities while maintaining competitive pricing. Production oversight becomes practical when facilities operate within reasonable travel distances, eliminating communication barriers that complicate overseas supplier relationships.

Cost & Efficiency Gains from Onshoring Components

Truck manufacturers who move spacer and lock plate production to domestic facilities achieve immediate financial advantages. These cost reductions stem from eliminated international logistics expenses, reduced inventory requirements, and accelerated production cycles that directly impact profitability.

Lower shipping and tariff expenses

Domestic spacer and lock plate production eliminates the unpredictable cost structure of international shipping. Companies avoid freight charges that have increased shipping costs by over 77% since 2021. Aluminum import tariffs jumped from 10% to 25% in February 2025, forcing some manufacturers to increase their annual metal component budgets from seventy thousand dollars to more than two hundred thousand dollars. Domestic production provides complete protection against these tariff fluctuations while eliminating freight expense entirely.

Reduced inventory holding costs

Inventory holding costs typically consume 20-30% of total inventory value through warehouse space, insurance premiums, taxes, and labor expenses. Domestic suppliers reduce these costs substantially by enabling manufacturers to operate with lower safety stock levels. Components arrive predictably and rapidly from nearby facilities, eliminating the buffer inventory required for overseas suppliers. Companies implementing just-in-time delivery systems minimize holding costs by timing component arrivals precisely when needed. This reduction in tied-up capital frees resources for other operational investments.

Faster production cycles and delivery

Current industry standards require four to six-month lead times for factory orders without upfitting. Domestic suppliers can reduce these timeframes to weeks rather than months. Production facilities located near assembly operations allow manufacturers to manage timelines more effectively, responding quickly to changing market conditions. This velocity advantage creates competitive differentiation as companies deliver finished trucks faster than competitors dependent on overseas component suppliers.

Improved Quality and Control in Domestic Manufacturing

Quality control represents the fundamental advantage of domestic spacer and lock plate production. Manufacturing facilities located within oversight distance of assembly plants provide quality assurance capabilities that overseas suppliers cannot match.
