SPC Performance 25710 1.5" Jounceshock

The SPC Performance 25710 is a 1.5" stroke Light Racing JounceShock — a patented secondary bump-shock designed to dramatically increase your suspension's capacity and performance. Built on a compact 6" base unit, it fits in tight chassis spaces while supporting 1:1, 2:1, or 3:1 motion ratios, making it highly versatile for custom off-road builds, rock crawlers, and towing applications.

When the suspension compresses, the shaft drives into the JounceShock body and pressurizes an internal nitrogen charge. This delivers a smooth, exponential increase in resistance — like an air spring — instead of the harsh force spike associated with conventional bump stops bottoming out. The result is superior bottoming protection, improved stability and handling at all speeds, and reduced stress on the vehicle and driver.

Key Features:

• 1.5" stroke in a compact 6" base unit — ideal for tight-clearance installations
• Twin-tube construction with 2.375" diameter bore
• Nitrogen and oil-filled internal construction for consistent, progressive damping
• Externally adjustable compression and rebound settings
• Threaded top mount for reduced fabrication and installation time
• Fully rebuildable design using hardened, corrosion-resistant materials
• Supports 1:1, 2:1, and 3:1 motion ratios
• Compatible with SPC Domed Foot (#25602), Cupped Rubber Foot, 15° Flex Mount (#25501), and fixed mounts
• Made in the USA

The 25710 JounceShock is sold individually and is compatible with a range of SPC Performance mounting hardware and foot accessories, allowing full customization for solid axle, independent suspension, and fabricated bracket applications. California Proposition 65 warning applies.
