PDD 24v Cummins Valve Springs

Your choice of Power Driven Valve Springs for 24v Cummins!

The Power Driven 104 lb. 24v Cummins 4.5K Performance Valve Springs were designed with performance in mind. We recommend these valve springs for engines that are pushing over 45 psi boost and/or 3,200 rpm. These performance valve springs will help prevent valve float, therefore allowing your engine to run more efficiently and make more power safely.

24v Cummins 4.5k Valve Springs Features:

• Helps prevent valve float
• Increased performance
• Rated up to 95 psi boost/drive pressure
• Rated up to 4,500 rpm on stock locks and keepers
• Less cam wear than 110 lb. springs

Power Driven Race Conical Valve Springs are:

• 134 lb 24v Race Conical Valve Springs
• Rated up to 6,000 RPM
• Designed for 100+ psi boost
• Fits 98.5 – 18 5.9L/6.7L 24v Cummins

The Power Driven 134 lb. 24v Race Conical Valve Springs were created to address valve float on high-performance 24v Cummins race engines, making 100+ psi boost pressure. In testing various available 24v springs, we found that valve float and resulting cam, lifter, valve, and retainer damage was common as over 5,000 is reached or as boost surpassed 100 psi. After destroying tappets and a camshaft on Todd’s 6.4L P-pumped 24v and destroying valves and chromoly retainers on Myer’s 6.7L common rail, we have developed a new race conical valve spring with enough seat pressure to handle 100+ boost and a conical design to dampen valve spring harmonics that occur between 5,000 and 6,000 rpm.
