Timbren Industries FRTT350F Rear Severe Service Suspension Enhancement System

The Timbren Industries FRTT350F Suspension Enhancement System is a severe service rear suspension upgrade designed specifically for Ford F-250 and F-350 Super Duty trucks. This kit uses single-convoluted Aeon rubber springs designed exclusively for truck campers and top-heavy loads, resisting weight more aggressively to keep your vehicle level and your ride smooth.

Key Features:

• 8,000 lb weight capacity rating
• Laser cut steel brackets precision bent and powder-coated for quality fit
• Progressive spring rate Aeon rubber springs that push back harder as load increases, eliminating squat, sway, and roll
• Zero post-installation maintenance - no air lines to run, no pressure to check, no leaks to watch for
• Can be installed and hauling in under 30 minutes from your driveway
• Simple bolt-on installation with included application-specific brackets and comprehensive instructions
• Maintains 1/2" to 1-1/2" gap between rubber spring and vehicle frame for comfortable unloaded ride
• Backed by lifetime warranty covering defects in material and workmanship

Ideal Applications:

This severe service kit is specifically designed for hauling top-heavy loads like truck campers or salt spreaders that require maximum stability. The Aeon hollow rubber springs absorb road shock and automatically adjust to uneven loads or road conditions, improving ride comfort and reducing the risk of bottoming out.

What's Included:

• 2 mounting brackets
• 2 patented Aeon SES hollow rubber springs
• All necessary hardware

Important Note: Even though you're increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
