Uprated Valve Springs & Pushrods

The standard type of push rod is adequate for road use. The tubular type is recommended for racing as they are stronger and are supplied shorter to suit a high compression cylinder head. They are also essential if using roller rockers.

It is essential to check the valve springs for coil binding, being solid at maximum lift, when using higher valve lifts; TriumphTune springs are designed for high lift cams. Remove lower spring collars if the TT springs are used - they are not required. The TT1307 springs are for road and sprint use; for greater lift and full competition use TT1308 springs can be used. The large diameter set TT1408 should be used with the high lift rocker kit.

Uprated valve springs are designed for TriumphTune and are suitable for all performance profile camshafts using the standard rocker ratio. Our competition springs are available in 2 specifications: Standard diameter are an interference fit; allowing up to 9000rpm and a maximum of 0.490 valve lift. Larger diameter springs allow better control of the valve for high lift and high rev applications. Standard valve caps are strong enough for all applications; however TriumphTune light-weight alloy caps also reduce valve loading and there-fore wear on cam lobes, weight saving approximately 25%. Also see our bronze valve guides and competition valves for further tuning.
