Product Overview
HKS Fine Tune Timing Belt 174Y – Toyota 3S-GE | 24999-AT005
Upgrade your engine’s timing system with the HKS Fine Tune Timing Belt 174Y for Toyota 3S-GE engines (24999-AT005). Developed for performance applications, this reinforced timing belt is engineered to provide dependable camshaft timing, improved tooth durability and stable belt operation under demanding engine conditions.
Whether you’re maintaining a Toyota Altezza RS200, restoring a late-model Toyota MR2 SW20 or preparing a 3S-GE-powered vehicle for spirited driving, the HKS Fine Tune Timing Belt offers a performance-focused alternative to a conventional replacement belt.
Designed specifically for selected Toyota 2.0L 3S-GE engines, this 174-tooth belt features a 25.4 mm width and advanced tooth construction.
Why Choose the HKS 3S-GE Timing Belt?
The timing belt plays a critical role in maintaining synchronisation between the crankshaft and camshafts. Reliable valve timing is essential for engine operation, particularly in high-revving performance applications.
HKS has developed its Fine Tune Timing Belt range with several important engineering features:
Reinforced H-NBR Rubber Construction
The timing belt uses high-strength H-NBR rubber in its tooth construction, providing additional durability for demanding engine applications.
Optimised Tooth Profile
HKS uses a manufacturing approach that forms the belt teeth into their intended shape, helping maintain tooth integrity and reduce the possibility of belt tooth skipping under demanding loads.
Stable Belt Tension
The belt is designed to maintain stable tension as engine temperatures change, helping support consistent timing system operation.
Engine-Specific Design
Rather than relying on a universal belt specification, HKS selects belt dimensions and construction for individual engine applications.
Suitable for Performance Engine Builds
The HKS Fine Tune range is designed to work effectively in performance applications, including engines fitted with compatible adjustable camshaft pulleys.

Why Upgrade to an HKS Fine Tune Timing Belt?
Performance engines depend on precision, reliability and correctly maintained timing components.
