Engine builders have relied on mediocre thread inserts for far too long. Brands X, Y, and Z back out. They pull out. They wear out. They’re a pain to install. They require special, pricey tooling. That’s why we're excited to introduce RaceSerts. Here’s what you can expect from RaceSerts. PERMANENCE
RaceSerts come with a LifeTime Warranty. The Warranty covers whatever part you repair, for the life of that part, whether it’s a block, a head, or a transmission: anything and everything. It’s a performance warranty, not just parts and materials.
No thread-wear. Ever.
No backing out. Ever.
No pulling out. Ever.
FAST, EASY INSTALL
1 minute or less with a hand ratchet
15 seconds or less with an impact
No special tooling needed
RaceSerts are self-tapping and self-aligning. That means they require no tap, and they go in straight and true.

Instructions:
- Drill out the damaged threads to make your pilot hole.
- Assemble the install bolt as shown. Apply tapping fluid to the RaceSert.
- Drop the RaceSert into the hole. Seat the RaceSert in the hole by firmly tapping the bolt all around its edges 4 or 5 times with a hammer.
- Turn in the RaceSert with a long-handled ratchet until the nut bottoms.***
- Secure the nut with an open-end wrench so it doesn’t move. Then back out the bolt.
- If the RaceSert isn’t quite flush with the surface, reinstall the bolt assembly and give it another turn or two. To avoid scoring the surface, don’t overturn.
***NOTE: A faster alternative is to start the RaceSert with a ratchet - 3 or 4 turns – then finish the installation with a 3/8” drive impact driver.
Kit Includes :
- 5 RaceSert Inserts
- 1 S7 tool (steel hardened installer bolt with nut and washers)
