Get the level of compression back up to where it belongs by replacing piston rings or pistons instead of burdening yourself with major repairs. Our warehouse is full of original spare parts and tuning and spare parts such as pistons, gasket sets, piston rings. Piston rings are the connecting pieces between piston and cylinder bore. Therefore, they have to withstand heavy loads, are subject to wear and should be replaced regularly. Loss of compression, decreased performance and starting problems are clear signs of worn out piston rings. Piston ring kit / s = full kit, 2 piston rings Piston Piston ring = single, Standard size = original size 1. OS / 2. OS = 1 oversize, second oversize, etc = Indicates the diameter of the cylinder! L pistons ring = piston ring with L-shaped profile, also known as Dykes ring SIP-TIP: be sure to fit piston rings carefully, do not pull too hard, risk of breakage, pay attention to the piston rings gap, the type and the design, of the trapezoidal segments have only one mounting direction! ### 3514741B (MALOSSI)
