Our 1 3/4 OD x .125 Wall tube is extruded from 6061 aircraft quality aluminum. This material is perfect for custom intake builds with a smaller port shape on the head. This material works in conjunction with our 1.75 velocity stacks for simple installation.
**Specific Shipping info**
USPS international shipping limits max length to 44 inches. If ordering large quantities, please call.
RMR also reserves the right to charge for extra shipping charges for large quantities of rail ordered through our online store given the shipping calculator doesn't always cover for the weight/length.
