2003-2018 Cummins 5.9L/6.7L 24V Manton Conical Valve Spring Kit (D-105-KIT-24v)
Transform your Cummins engine with Manton’s complete valve spring and retainer kit, designed to enhance performance, durability, and longevity. This drop-in package offers 105 lbs. of seat pressure and 165 lbs. of open pressure at 0.420 lift, crucial for vehicles with upgraded performance cams.
Engineered with Manton’s exclusive “Pressure Tower” conical spring design and “Ultra Light” steel retainers, this kit ensures the highest strength-to-weight ratio and unmatched reliability across any application, whether your truck serves daily commutes or competitive racing.
The springs are optimized for up to 75 PSI boost, backed by 105 lbs. of seat pressure. Manton provides heat-treated spring shims to adjust seat pressure as needed for different boost levels. For older trucks from 1998.5 to 2002, where valve spring pockets may be too tight, Manton offers a valve spring pocket cutter to enlarge the pocket for a perfect fit with this advanced spring kit.
