Show original supplier description
The Insane Shafts IS-001 is a high-performance left-hand drive axle engineered for demanding applications, particularly those involving H-series engine swaps in specific Honda and Acura vehicles. Constructed from robust chromoly steel, these axles are put through a proprietary annealing and heat treatment process, enabling them to withstand power demands of up to 500 wheel horsepower, making them a superior alternative to typical swap axles. The application list is extensive, covering 1988-2001 Integras (DA, DC) and 1988-2000 Civics/CRXs/Del Sols (EF, EG, EK) when equipped with an H-series engine (H22/H23) and transmission. The spindle nut size is 32mm, and it is specifically for the LH (left-hand drive) side. The product weighs 18 lbs and has dimensions of 28 x 6 x 6 inches.
