Pro Shock ASB636B Small Body Threaded Aluminum Twin-Tube Shock 6-Inch Stroke

The Pro Shock ASB636B is a small body threaded aluminum twin-tube shock absorber from the Pro Shocks ASB Series, featuring a 6-inch stroke with split-valve (3 compression / 6 rebound) valving and included bearings. Designed for circle track, midget, mini sprint, and micro racing applications running coil springs, this shock delivers the precise driver feel and true damping performance that serious racers demand.

Key Features:

• Small threaded aluminum body — 1-5/8" O.D. lightweight construction for weight-sensitive race applications
• Twin-tube design with true valving for consistent, quality damping curves
• 6-inch stroke with split-valve configuration: 3 compression / 6 rebound
• Bearings included — ready to install out of the box
• Hand-built, one at a time — individually assembled and quality controlled
• Serial-numbered dyno tested — every shock ships with its own dyno graph as proof of quality
• Rebuildable and revalvable — long-term serviceability for ongoing season use
• Travel indicator and jam nut included

The ASB Series delivers the same quality damping curves as Pro Shocks' proven non-adjustable big body series in a compact, small-body threaded package. Compatible with coil-over hardware for coil spring mounting. Note: Must be installed with shaft pointing up for proper operation.
