Ratech
Smart Sleeve GM 8.2in
SKU: R013 11003
Moderate — 2–4 hours
Description
Ratech emphasizes that their shims are manufactured in-house using American-made hardened shim stock, differentiating them from competitors who may use softer sheet metal gauges. This ensures a broader thickness range and prevents issues like splitting under performance loads or difficulty achieving precise specifications with non-OEM gear sets.
