Engineered for LS-Powered Racing

Adapting a GM LS-series engine to a Powerglide transmission requires precision and strength. The JW Performance Transmissions Ultra-Bell is the ultimate solution for racers looking to combine modern LS power with the proven reliability of a Powerglide. This SFI 30.1 certified bellhousing is built to withstand the intense stresses of high-RPM launches and massive torque outputs.

Why Choose the Ultra-Bell for Your LS Swap?
