Billet H22 Timing Belt Tensioner With Walk Blocker H Series Prelude H2B Civic Si
Applications: For H22 h23 Vtec (blue top) F20B or similar DOHC H&F series VTEC Honda engines. Please note that power steering must be deleted alternator relocated to the lower position and timing belt cover must be removed.
Honda H & F series especially ones with high duration camshaft or milled heads are known to belt slap excessively along the long front side of the timing cover. This excess slack in the timing belt can cause the belt to skipping one or more teeth on the cam gears. A skipped tooth caught in time can result in a loss of a race due to reducing engine power but if not caught it can result in the piston to valve contact which requires an engine overhaul. This can all be prevented by installing our manual timing belt tensioner, our tensioner will properly support the front side of the timing belt to take away the slack. The unit bolts up directly to the stock Honda block and replaces the power steering bracket. Please note that the tensioner will require the delete of the factory power steering system and removal of the timing belt cover and alternator placed in the lower position see install picture for reference.
We also added the timing belt walk blocker, it prevents the timing belt from coming off the cam gears. This is a great investment to protect your engine!
