Timing Chain Kit 1350631040 Fit for 2010-2021 Toyota 4Runner Tundra 4.0L V6

This timing chain kit is designed to replace worn timing components and help restore accurate crankshaft-to-camshaft synchronization on compatible Toyota 4.0L V6 DOHC naturally aspirated engines. It includes lower and upper timing chains, three tensioners, guide rails, and idler and crankshaft sprockets for timing-system repairs or engine rebuilding.

Product Features

• Lower and upper chain replacement: Includes one lower timing chain and two upper timing chains, allowing all three chains to be serviced during the same repair.
• Heat-treated alloy steel chains: Constructed from high-strength alloy steel and heat-treated to improve wear resistance under repeated engine loads.
• Position-specific tensioners: A lower primary tensioner and separate left and right upper tensioners help maintain tension across the chain system.
• Wear-resistant polymer guides: Four guide rails support controlled chain movement and provide wear-resistant contact surfaces.
• Idler and crankshaft sprockets included: Allows these sprockets to be replaced alongside the chains rather than retaining worn chain-contact surfaces.
