Why upgrade to the 8 Speed Transmission?
The 8HP70 is a stronger transmission that can handle more power. Another important thing about the 8 speed transmission is shift quality and efficiency. With our tuning, we are able to dial in the shift points of the transmission to maximize the performance coming from the engine in optimal RPM ranges. This can also be beneficial to those who have larger than stock tire sizes!
LT engine conversions have replace the LS engine swap for Jeep Wranglers
GM has released their best small-block V8 yet with the new Gen-V LT engine family! Therefore, the production of old generation GM LS engine blocks has all but halted. The LS3 crate engine from GM Performance is no longer available. No worries! Bruiser Power Solutions has designed, tested, and released the LX3 crate engine, an LT-based engine with port injection using a Gen-IV operating system. It’s a 6.6L torque monster without the tuning and RPM limitations of factory direct injection.
Bruiser Conversions developed this bolt-in V8 engine and 8-speed conversion for late Jeep Wrangler JK for hassle-free integration into your Jeep project!
