There is No substitute for cubic inches! This is the largest piston and liner kit that you can buy without machining the block on your Triumph TR3, TR4 and TR4A Engine. Each liner has been reinforced with a 2mm thicker body for more strength and greater stability. Each piston is a short skirt design making for lighter weight and less drag plus each piston has drilled oil return holes instead of oil slot for greater strength. With each liner being bored to match the piston, fitment and correct clearance will be assured. Each kit comes complete with Pistons, Liners, Deves Rings, Pins and Clips. No machining is required to your block; these press in just like the 86mm or 87mm liners. Open up the power potential in your Triumph Engine with this kit
