Classic Chassis – New!
We are proud to offer you our new 1969-1972 Chevy K5 Blazer Classic Chassis. Putting our 47 years of design and engineering expertise to work, we begin with 8 laser cut frame pieces of U.S. derived .134w steel. Each piece of the frame rail is fixture welded and ground smooth. The frame rails are then placed into a chassis fixture where we add front and rear crossmembers and center section. Compared to the factory frame rails, our engineers widened the rails ahead of the cab and narrowed them behind the cab. This allows you more room for headers and steering components, up front. While outback, this allowed us to mount the shocks outside the frame rails which maximizes roll stiffness and still have plenty of room for massive tires. The center section is comprised of 12 pieces of 1”x2” .120w U.S. derived steel adding even more rigidity. Center section design allows for 3” round tube exhaust to fit with room to spare. This is the most well thought out 1969-1972 K5 Blazer Chassis available today.
Our commitment to our customers, and our role in helping build a perfect ride, is at the core of our relationship with you. That’s why our Pro-Touring IFS comes standard. This American Made front end will provide the ultimate in handling, weight savings and strength. It is based on our Custom Modular truck spindle and bolt on steering arms. Proprietary geometry maximizes comfort and performance. Spindles come with 12” rotors and calipers and can be upgraded to 13″ or 14″ Wilwood 6 piston Brakes. The crossmember is moved forward to center the front wheel in the well. We use heavy duty componentry throughout to provide safe, long lasting enjoyment. The upper control arm mount design provides easy camber and caster adjustments. We have raised the front crossmember so it is now above the bottom of the frame rails. This helps provide ample ground clearance at significant ride height drop. Ridetech 1,000,001 mile warranty adjustable coilovers come standard up front.
Our engineers have made a performance 4-Link the standard rear suspension for the K5 Blazer chassis. Performance driven axle brackets provide not only anti-squat adjustments but also ride height without having to preload the coilovers. Fine tuning ride height further with the adjustable coil-overs is a breeze. Adjustable link bars allow fine tuning of wheelbase and pinion angle, eliminate wheel hop, and provide excellent axle control for big or small HP applications. Link bars and coilovers are mounted outside of the narrowed rear frame rails to provide better roll control. The rebound adjustable Ridetech coilovers allow you to retain comfort and the utility you expect from a pickup. Ridetech 1,000,001 mile warranty adjustable coilovers come standard on the rear.
