E36 Heavy Duty 14mm Performance Polyurethane Differential Bushing Set
Eliminate power-robbing rear-end flex and upgrade your E36’s dynamic handling with the Turner Motorsport Track-Spec Differential Bushing Package. On the track or aggressive backroads, factory rubber differential mounts distort heavily under load, delaying throttle response and compromising rear alignment geometry. This complete package locks down the front and rear differential mounting locations, routing torque directly from your right foot to the pavement for maximum acceleration and predictable corner exit.
Engineered for drivers who demand race-bred chassis feedback without the unrefined harshness of solid metal mounts, this package equips your E36 with a heavy-duty polyurethane upgrade. Up front, a stiff 95A polyurethane bushing is anchored by a high-strength M14x1.5 Grade 12.9 bolt, overcoming the notoriously weak factory M12 bolt setup to survive high-RPM launches and severe track abuse. Out back, 88A polyurethane rear bushings stabilize axle load shifts to keep the rear end planted through turn-in and high-G cornering. Lightweight, black-anodized 6061-T6 aluminum inner sleeves deliver structural integrity in severe racing environments.

FEATURES
Race-Proven Drivetrain Rigidity: Full front and rear bushing replacement locks the differential firmly to the subframe to prevent geometry shifts under heavy power.
Heavy-Duty M14 Front Conversion: Upgrades the factory M12 hardware to a robust Grade 12.9 M14 bolt to end front differential bolt failure under load.
Track-Tuned Polyurethane: Combines a high-durometer 95A front mount with 88A rear bushings for immediate throttle response, minimal power loss, and sharp chassis feedback.
Billet Aluminum Inner Sleeves: Anodized CNC-machined 6061-T6 aluminum sleeves ensure maximum durability and rust resistance under harsh racing conditions.
Durable & Weather-Resistant: Polyurethane material resists track fluids, heat, and chemical wear far beyond standard OEM rubber. Includes assembly lubricant for quiet operation.
MOUNTING & FITMENT NOTES
Required Tech Note: Upgrading to the heavy-duty M14x1.5 front bolt requires drilling and tapping the original M12 differential mounting hole.
