With expanded surface area, deeper oil grooves, and hardened bearing steel inserts, these upgraded phasers solve the M156’s chronic phaser failures for $1,799 – saving over $1,000 vs discontinued OEM phasers ($2,796). Complete set includes phaser assembly bolt kit and prepaid core return label.
$1,799.00
M156 cam phasers fail between 60k-100k miles, causing rough idle, check engine lights (P0011, P0021, P0016), and timing issues. Factory phaser plates warp over time, leading to oil seepage and inconsistent cam timing.
OEM replacement phasers are DISCONTINUED – were $699 each ($2,796 for a set of 4).
VRP SOLUTION – UPGRADED PHASER PLATES
Our rebuilt phasers feature American-made 4340HT billet steel phaser plates that outperform factory parts:
✓ Increased Surface Area – Expanded bottom keyhole reduces wear, extends life
✓ Deeper Oil Groove – Faster locking/unlocking for better cam response
✓ 52100 Hardened Bearing Steel Insert – Extreme durability under load
✓ Precision Ground – Absolute parallelism prevents warping
✓ 4340HT Billet Steel – Significantly stronger than OEM cast components
Made in USA – Each phaser tested before shipment.
