Good To Know
Q: Will this fit my stock 1975 GMC C15? A: Yes, the 89340S line fits C15 models from 1971 to 1987, including stock height trucks. The extended design also works if you have a lift kit installed.
Q: Are these lines pre-bled or do I need to bleed them after install? A: These are solid metal brake lines, so you will need to bleed the brake system after installation. This ensures all air is removed for safe braking performance.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
