PPE EXHAUST MANIFOLD BOLT & SPACER KIT 216110100 | 1998.5-2018 CUMMINS 5.9L/6.7L

Replace stretched or broken exhaust manifold hardware with the PPE Exhaust Manifold Bolt & Spacer Kit. Designed for 1998.5–2018 Cummins applications, this kit addresses common failures caused by repeated heat cycles that lead to bolt fatigue, stretching, and exhaust leaks.

PPE bolts are centerless ground and precision rolled to reduce stress concentrations and improve overall strength. The included spacers help manage thermal expansion, reducing load on the bolts and preventing premature failure.

Key Benefits:

• Fixes common exhaust manifold bolt failures
• Reduces stress from heat expansion with included spacers
• Improves durability and long-term reliability

Features:

• Centerless ground for consistent strength and accuracy
• Precision-rolled threads for durability
• Spacers help prevent bolt stretch and fatigue
• Black oxide finish for corrosion resistance

Fitment Notes:

• Fits 1998.5–2018 5.9L / 6.7L Cummins
• 2003–2007 5.9L requires use of factory heat shield
• Not compatible with OEM manifolds on 1994–1998 5.9L (fits aftermarket manifolds only)
