Total Seal is the leading company in the development of innovative ideas in piston rings, and has done a great deal of testing in an attempt to solve the complexities of sealing a cylinder under all circumstances, like high RPM s, Big Bore sizes, high temperature and other severe conditions. They offer two different ring sets for the Harely-Davidson market, the TS1 set and TSS set. The TSS sets are designed for stock street applications. They have a moly coated cast iron top ring. This is higher quality top ring than what would be used in OEM applications. The second ring is the Gap-less design patented by Total Seal and also found in the TS1 sets. The Total Seal Gap-less design eliminates the end gap problem and keeps the gap blocked as ring and cylinder wall wear occurs. TS1 sets are the highest performance rings on the market. They have a Moly Max plasma ductile iron top ring. This ring will hold up to extreme heat and detonation and is used in nitro, blown and nitrous applications. Total Seal highly recommends this ring for high performance street applications, where the compression ratio has been raised. The second ring is the Gap-less design. This ring is the same on all applications. It consists of two pieces, a ring and a rail and is so constructed that the blow-by is reduced to 2% or less and remains at this basic level trough out the life of the ring set. The Gap-less ring seals so well, the oil temperature actually goes down because of the lesser blow by. The oil ring in the TS1 set is a 3 piece design with a stainless steel expander and tool steel chromed faced rails. Total Seal piston rings sets are sold in sets for one single piston. Available in standard, and oversize.
Note: Bore sizes 3 3/4", 3 13/16", 4", 4 1/4", 4 3/8" and 4 1/2" are available in TS1 quality only. Not all Big Bore sizes are available. It may be needed to gap a larger size piston ring down to the size required.
