EMPI Off-Road Steering Wheel Quick Release | Dune Buggy & Race | Splined 7/8" Shaft, 3-Bolt (17-2570-0)

EMPI Off-Road Steering Wheel Quick Release — Splined 7/8" Shaft, 3-Bolt Flange

Engineered for maximum durability in high-torque steering environments, the EMPI 7/8" Splined Quick Release is the professional choice for trophy trucks, heavy-duty sand rails, and competitive off-road racers. This two-piece set allows immediate removal of your steering wheel, providing essential clearance for entering and exiting cramped race cockpits and ensuring rapid egress in an emergency.

A precision-machined fine-spline engagement eliminates the "play" found in cheaper hex-style disconnects, and the heavy-duty pull-ring mechanism provides a positive lock that keeps your wheel securely attached through the harshest whoops and landings.

Vehicle Fitment

A universal racing component requiring professional fabrication and welding to your steering column:

• Race-spec sand rails: 3-bolt flange, weld-on to 7/8" shaft
• Trophy trucks / Class 1: 3-bolt flange, weld-on to 7/8" shaft
• Rock crawlers: 3-bolt flange, weld-on to 7/8" shaft
• Baja Bugs (full cage): 3-bolt flange, custom column required

Key Features & Benefits

• Heavy-Duty 7/8" Bore: Welds onto a 7/8" steering shaft for greater weld surface and strength than standard 3/4" units.
• Precision Fine-Spline Drive: Tight, repeatable fit every time the wheel is reinstalled, maintaining steering alignment.
• Dual-Pattern Mounting Holes: 3-bolt flange drilled and tapped for both 5/16-18 and 1/4-20 bolts.
• Hollow Steel Shaft: Weld-on splined stub is hollowed to minimize weight while keeping torsional strength.
• Rapid Disconnect: Spring-loaded pull-ring removes the wheel one-handed, even with racing gloves.
