Pro-Touring Chassis

Original price was: $21,159.00.Current price is: $19,043.00.

We are proud to offer you our new 1969-1972 Chevy K5 Blazer Pro-Touring Chassis. Putting our 50 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 a center section.

Compared to the factory frame rails, our K5 Blazer Pro-Touring Chassis engineers widened the rails ahead of the cab and narrowed them behind the cab. In turn, this provides you more room for headers and steering components, upfront. While outback, this allowed us to mount the shocks outside the frame rails which maximizes roll stiffness and still has 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. The center section design allows for 3” round tube exhaust to fit with room to spare. In addition, the rear frame rails have been stepped 8″ to provide an extremely aggressive ride height and low center of gravity. With 335/30R18 tires on all four corners, your frame rails will be 4″-4.5″ off the ground. This is the most well-thought-out 1969-1972 K5 Blazer Pro-Touring 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. Therefore, that’s why our Pro-Touring IFS comes standard. This American Made Pro-Touring IFS 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 wheels 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. As a result, this helps provide ample ground clearance with a significant ride height drop. Ridetech 1,000,001 mile warranty adjustable coilovers come standard up front.

The Torque Arm rear suspension was designed to eliminate the suspension bind that occurs when cornering using the stock conventional leaf spring suspension & aftermarket 4-links. The Torque Arm features a telescoping slider at the front of the arm that rotates as the car goes through suspension travel and articulation. Moreover, this allows the cars handling to be controlled by the coil-over shocks and the rear sway bar with no suspension binding variables. The kit allows for a lowered stance, greater rear axle control, and dramatically improved handling. There are 3 height adjustments on the axle brackets in one-inch increments. You also have the ability to fine-tune the ride height further with the adjustable coilovers. Adjustable link bars allow fine tuning of wheelbase and provide excellent axle control for today’s modern high-performance engines. Link bars and coilovers are mounted outside of the narrowed rear frame rails to provide better roll control. Furthermore, the rebound adjustable 1,000,001-mile Ridetech coilovers provide outstanding performance and reliability.

TCI Engineering & Currie Enterprises complete 9-inch Ford Rearend. TCI Engineering fabricates all of its 9-inch Ford Rearend housings in-house using only high-quality 100% Curries 9-Plus rear-end components. Modeled after the popular factory 9” Ford housing which is now nearly extinct. The 9-Plus is made of U.S. supplied premium grade formed steel. Strength and rigidity is increased by using thicker gauge steel. The housing comes with American Made 3” O.D. x .188” wall 1026 D.O.M. steel tubing. 100% new Billet steel 9-Plus late model large bearing (Torino style) housing ends. Finally, exhaust routing is made easier and bracket clearance is increased due to the shape of the housing.

Currie Enterprises provides the 9-Plus Nodular Iron “Sportsman 3rd Member Case”. Cast out of 65,000 p.s.i. nodular iron and features 3.062” carrier bearing bores, with a 1350 yoke, and 31 spline carrier. These brand-new Currie cases are now standard on all complete chassis from TCI Engineering.

This 9” Sportsman 3rd Member gear is 100% new. 31 spline high performance 1541 forged induction heat-treated alloy axles come standard. Axles come with a 2.80 center register hub and 2.5” brake space for later model big Ford housing ends.  Additionally, each set of axles comes with USA Made large tapered roller bearings with seals, heavy-duty retainer plates, 1/2” wheel studs pressed on. Axles come with both 5 x 5″ Chevy truck bolt pattern. Standard width is 60″ Axle Flange to Axle Flange but custom widths are available.

All TCI Engineering products come with our Dual Warranty. 6 Year, 60,000 Mile Warranty on wear and tear items like bushings, tie rods, & ball joints. Any items built in-house by TCI Engineering such as link bars, control arms, spindles, crossmembers, etc come with a Lifetime Warranty.
