Camshaft Holding Tool Kit Fit for 2.7L 3.5L 3.7L Cyclone V6 & EcoBoost

This Camshaft Holding Tool Kit is specifically engineered for Ford Cyclone (Duratec) series V6 engines, serving as a direct replacement for OEM specialty tools 303-1248, 303-1530, and the RT11 spline socket. Whether you are replacing timing chains, servicing VCT variable camshaft phasers, or performing cylinder head work, this kit securely locks both camshafts at TDC to prevent misalignment and costly engine damage. Fitment: Ford Edge (2007-2018), Explorer (2011-2018), F-150 (2011-2014), Fusion (2007-2018), Mustang (2011-2017), Taurus (2008-2014), Transit (2015-2018), Police Interceptor (2015-2018); Lincoln Continental (2017-2018), MKS (2009-2016), MKT (2010-2018), MKX (2007-2018), MKZ (2007-2016), Navigator (2015-2017); Mercury Taurus X (2008-2009), Sable (2007-2011), Milan (2008-2012). Engines: 2.7L, 3.5L, 3.7L V6 (naturally aspirated and EcoBoost turbo), plus 4.0L 4-valve V6 variants sharing the same architecture. Kit includes: Left and right camshaft holding fixtures, timing chain tensioner retaining pin, and RT11 spline socket (1/2" drive). All tools are forged from high-strength alloy steel and chrome-molybdenum for exceptional durability and resistance to wear, meeting professional repair shop standards. The set comes in a blow-molded carrying case with custom foam liner for safe storage and easy transport. Quick workflow: 1) Rotate crankshaft clockwise to TDC and align timing marks. 2) Install both fixtures to lock camshafts. 3) Compress tensioner and insert retaining pin. 4) Use RT11 socket with torque wrench for VCT bolt service (replace bolts per factory spec). 5) Reassemble, manually rotate 2 full turns, and verify fixtures reinstall smoothly before starting the engine. Always follow factory service manual for torque specifications.

• [Precision Fitment] Precision-engineered for Ford Cyclone 2.7L, 3.5L, and 3.7L V6 engines, including EcoBoost turbo variants. Replaces OEM tools 303-1248, 303-1530, and RT11. Compatible with Edge, Explorer, F-150, Fusion, Mustang, Taurus, Transit, Police Interceptor; Lincoln Continental, MKS, MKT , MKX , MKZ, Navigator; Mercury Milan, Sable, Taurus X. Not for 4-cyl, V8, or older 4.0L SOHC. Always verify your engine displacement and VIN before ordering to ensure perfect compatibility.
• [Cam Lock at TDC] Two robust fixtures lock both left and right camshafts precisely at Top Dead Center (compression stroke). This mechanical stop prevents unintended rotation during timing chain or VCT phaser work, eliminating timing jump and valve-piston contact. To use: align crank marks, slide fixtures into rear cam slots until fully seated. Never rotate crankshaft while locked. Designed for a secure, wiggle-free fit.
• [Complete Kit with RT11] Includes left/right fixtures, tensioner retaining pin (replaces 303-1530), and RT11 spline socket for VCT bolts. RT11 has 1/2"" drive with T11 internal spline – prevents cam-out and stripping. Pin locks hydraulic tensioner plunger to maintain chain tension during service. All packed in a blow-molded case with foam inserts for organized storage and portability.
• [Industrial-Grade Durability] Fixtures drop-forged from high-strength alloy steel, heat-treated for rigidity and bending resistance. RT11 socket made of chrome-molybdenum (Cr-Mo) steel for exceptional toughness and wear resistance. Black oxide finish resists rust and shop chemicals. Precision-machined for exact fit on cam slots and phaser bolts – built for repeated professional use.
• [Safety & Operation] Always rotate crankshaft clockwise only – never reverse to avoid chain jump. Torque VCT bolts to OEM spec with a torque wrench; RT11 socket is for hand-torque only, NOT impact guns. After reassembly, hand-crank 2 full turns to verify free movement, then reinstall fixtures to confirm TDC alignment. Replace phaser bolts with new ones per factory recommendations
