FAQs
Q: Do I have to line-hone after installing the girdle?
A: It's highly recommended. Clamping the caps with a girdle can slightly change bore alignment; a line-hone verifies roundness and bearing life.
Q: Will this fit with my aftermarket oil pan?
A: Most pans work with minor clearance checks. Always dry-fit the pan and pickup, and verify rotation of the crank before final torque.
Q: Can I run this on a daily-driven truck?
A: Yes. The added rigidity benefits both performance and longevity, especially for tuned or towed setups.
Q: Does it include bearings or gaskets?
A: No. Bearings and gaskets are sold separately (see recommended parts below).
