COMP Cams® High Energy™ Timing Sets for Jeep 4.0L Applications

High Energy™ Timing Sets for Jeep 4.0L applications provide exceptional durability in any stock to mild performance application.

COMP Cams® now offers two excellent performance upgrades that exceed all original equipment timing chain set specifications without breaking the bank. These premium quality link belt type timing chain sets improve durability when replacing a worn out or stretched stock timing chain set.

Part #3237 for Jeep 4.0L 1999-06 applications features a precision cast iron camshaft gear, a steel crank sprocket and a durable link belt chain, a perfect option for stock to mild performance builds. Part #3219 is for the 1964-98 Jeep 4.0L and features a wider link belt chain for less stretch and a stronger tooth design on both the cam and crank sprockets for improved durability. The #3219 is ideal for heavy-duty applications but is also the perfect upgrade for stock type rebuilds.
