Infiniti G37 Hotchkis Front and Rear Sway Bar Installation Guide
Infiniti G37 Hotchkis Front and Rear Sway Bar Installation Guide
Upgrading your sway bars is a proven method to eliminate chassis roll and dial out factory understeer. This direct driveway installation will significantly improve how your G37 handles technical corners.
The Short Answer (TL;DR)
Installing Hotchkis front and rear sway bars on an Infiniti G37 requires roughly two hours using standard hand tools, a breaker bar, and suspension ramps. You must remove the front engine splash shield and may need to lower the rear mid-pipe for clearance. Always lubricate the polyurethane bushings with silicone grease to prevent suspension creaking.
The DIY Process Overview
Securely elevate the vehicle on ramps or jack stands and chock the wheels. You will need 10mm, 14mm, and 17mm sockets, a 14mm wrench, an 18-inch breaker bar, a flathead screwdriver, and penetrating fluid. Keep a 19mm open-end wrench readily available, as the front endlinks often spin during the removal process.
For the front sway bar, remove the plastic splash guard utilizing your 10mm socket and screwdriver. Spray the 17mm endlink nuts with penetrating fluid before applying the breaker bar. Unbolt the 14mm bracket nuts to extract the factory bar. Liberally coat the internal bore of the new Hotchkis bushings with the provided silicone grease. Bolt the new front assembly into position, torquing the bracket nuts to 37 ft-lbs and the endlinks to 62 ft-lbs.
For the rear bar, remove the rearmost 10mm splash guard bolt for clearance. Depending on your exhaust configuration, you may need to loosen the 14mm mid-pipe bolts and lower the exhaust to remove the OEM bar. Remove the 14mm rear endlink nuts and 14mm bushing bracket nuts. Grease the new rear bushings, position the Hotchkis bar, select your stiffness setting, and torque the rear brackets to 25 ft-lbs and endlinks to 41 ft-lbs.
Why You Should Upgrade While You're In There
Because you are already under the chassis and lowering the exhaust mid-pipe to access the rear sway bar mounts, this is the optimal time to upgrade restrictive factory exhaust components. Swapping the factory Y-pipe or mid-pipe while the hardware is already unbolted eliminates redundant labor and yields noticeable throttle response improvements.
Recommended Upgrade: Performance Cat-Back Exhaust System or High-Flow Y-Pipe
Frequently Asked Questions
How do I adjust the stiffness on the rear Hotchkis sway bar?
The Hotchkis rear sway bar features three adjustment holes for tuning. On a G37 Sport model, the outermost hole provides a 5% stiffness increase, the middle hole yields a 30% increase, and the innermost hole provides a 60% increase over factory specs. Use the outermost or middle hole initially, as the stiffest setting can induce aggressive snap oversteer.
Why is my new sway bar creaking over speed bumps?
Suspension creaking is strictly caused by dry or improperly lubricated polyurethane bushings. You must use high-grade silicone grease on the internal bore of the bushings during assembly. Never use lithium grease, as it degrades quickly and washes out. Utilize the integrated Zerk fittings on the aftermarket brackets to inject fresh silicone grease every 12 to 18 months.
