Flawlessly passing 422-hour WOT (Wide Open Throttle) durability tests and helping the Cadillac CTS-V bring home SCCA SPEED World Challenge GT championships, Katech pistons have been proven on the dyno, at the track and off-road in the SCORE Desert Series and Dakar Rally. Designed in-house, all are machined in Katech's own CNC department to exacting tolerances.
Stocked in 9:1, 10.4:1, 11:1, 12:1 and 14:1 compression ratios, the company offers a piston for every LS7 application including engines with nitrous oxide and/or forced induction. Starting with specially made aluminum forgings manufactured of 2618 or 4032 material, the pistons are stronger yet lighter than production pistons.
Katech Performance LS7 pistons are engineered with custom features including gas ports, large radius valve pockets, precision flatness ring grooves, anti-detonation bands, accumulator groove, exact LS7 ring pack and land dimensions, tanged round wire pin locks and select hard-coat anodizing to minimize detonation as well as micro-welding of the top ring in high horsepower applications. Also, skirts can be Dart DCI MOS Teflon coated. Optional DLC (Diamond-Like Carbon) coated pins are available to complete ultimate race durability packages.
Katech Performance, the aftermarket performance division of Katech Inc., engineers and manufactures race-proven crate engines and components for all LS engines including solid belt tensioners, coil relocation brackets, cylinder heads, valve spring retainers, pistons, push rods, throttle bodies and valve covers, among other high-performance products for the street and track. In addition to engines and components, Katech Performance also develops highly refined vehicle packages for Corvettes and other LS-powered vehicles.
