Features

• Hex flange head — no separate washer required
• Black oxide finish for corrosion resistance
• Grade-rated for high-temperature turbo flange use

What’s Included

• 4 hex flange bolts — black oxide finish

Why Replace These Bolts

The collector-to-turbo flange bolts sit in the hottest, dirtiest spot on the exhaust side and routinely seize, round off, or snap during turbo service. Replacing them with fresh hardware during any turbo job ensures clean torque, proper flange sealing, and bolts that will actually come out the next time you need to pull the turbo.

Every SPOOLOGIC bolt kit is covered by a 1-Year Limited Warranty against defects in materials and workmanship from the date of purchase. Warranty coverage requires that the failed hardware first be shipped back to SPOOLOGIC for inspection. If SPOOLOGIC determines the failure was caused by a defect in materials or workmanship, the hardware will be replaced at SPOOLOGIC’s discretion.
