CASE SAVERS

Case savers are threaded inserts that are installed into the engine case to provide much greater surface area and clamping force than a standard threaded hole. Whether you are repairing a damaged case or proactively reinforcing a new build for high-performance use, these inserts are a mandatory upgrade for any serious engine builder. They ensure that your cylinder heads remain properly torqued, preventing compression leaks and head lift.

Our Case Saver Selection Features:

• 8mm & 10mm Internal Diameters: Available for both early 10mm head studs and the more common 8mm "thin-bodied" performance studs.

• Oversized External Threads: Designed to bite deep into the engine case material, distributing the load and preventing the insert from pulling out.

• Hardened Steel Construction: Provides superior thread durability compared to the soft magnesium or aluminum of the engine block.

• Performance Essential: A must-have for high-compression, big-bore, or turbocharged air-cooled engines where head clamping is critical.

• Complete Sets: Conveniently packaged in sets of 16 to ensure every head stud on your engine has a secure, reinforced mounting point.

Don't let soft case threads compromise your engine's reliability. Build your motor with the strength and precision it deserves. Shop the case saver collection at Appletree Auto today and take advantage of Free Shipping on all orders over $75!
