Get a great rear suspension for your classic with this 1947-53 Chevy pickup 1/2 ton truck and the 1954 Chevy pickup 1/2 ton truck (with slight installation frame modifications) triangulated 4 bar rear suspension kit. This precision engineered kit includes bolt-on frame brackets, weld-on axle brackets, tubular steel bars, and chromolyadjusters with urethane bushings. This triangulated four bar rear suspension will greatly improve both the ride quality and handling of your 1/2 ton Chevy.

• Allowsthe do-it-yourself rodder to use the rear end of their choice
• Modern geometry and handling
• Chromoly four bars with urethane bushings
• Bolt-on frame brackets and shock crossmember
• The length of the upper bars is 16" eye to eye
• The length of the lower bars is 21.5" eye to eye
• 1/2 ton chassis application only
• Kit will locate rear axle centerline in the original factory housing center line, and as such, it retains the original wheel base and the tire/wheel will not be centered in the fender opening as they will be located in the original factory location.

NOTE: Finish will be plain steel, not powder coated as shown. When installing into a 1954 frame, due to the slight differences in the 1947-53 and 1954 frame, additional installation modifications will be required for the install into the 1954 frame at the shock crossmember area with regards to the width.Please note that this is applicable only to the 1/2 ton chassis application and will not fit the 3/4 ton chassis applications.

Speedway Ford 9 Inch Posi Traction 3rd Member Assembly, 31 Spl, 3.50

Assembled by Professionals

Hand-assembled by trained experts in-house, our Ford 9-inch third members are built from quality components with an exact step-by-step process. We bring this combination of precision assembly and quality components to you at a price that can't be beat. We trust these third members so much, they're the go-to choice for our own rides, from the street to the track.

Tough, Nodular Iron Center Section

Our Ford 9 Inch Nodular Iron Third Member Center Section Carrier starts with a NEW casting with over 4 lbs. of additional material in critical areas. Nodular (ductile) iron is much more resistant to fracturing than OEM "gray"iron. Extra ribbing reinforces the case and rearmost pinion support (pilot bearing).

Thick, forged steel bearing caps surround the carrier bearings, all securely held in place with precision Grade 8 cap screws. The improvements continue with rugged billet steel adjuster nuts and heavy-duty keepers to ensure your ring gear settings are maintained. All mounting surfaces are precision machined to ensure a consistent, flat surface for a positive gasket seal (no more leaks on your shop floor). An oil fill plug is included.

Precision Assembled for Proper Ring Gear Teeth Pattern

Getting a proper pattern on the ring gear teeth is crucial. Our time-proven, step-by-step process ensures the correct backlash, preload, and proper amount of pinion shims to ensure the correct pattern on the ring gear teeth. Our gears use use cold-rolled 8620 steel, known for its long-wear and durability.

To ensure a proper gear pattern, we use a stronger "Daytona" style pinion bearing support to maintain that critical pinion depth setting. Stronger due to its larger bearings, our Daytona pinion support also uses the spacer-and-shim setup to maintain critical pinion depth settings under high load, unlike traditional crush sleeves which often compress further, take out your preload and lead to failure. With solid bearing spacers and the proper shims, we eliminate this problem and make setting preload easy and repeatable during installation, service and gear changes. Since preload is already set, simply torque the pinion nut to 160 ft./lbs. and you're good to go. The pinion gear is connected to our new, forged steel "Ford short” 1310-type pinion yoke.

Gear-Style Richmond Powertrax Grip ProDifferential

For the ultimate in putting power to the pavement, Richmond Powertrax Grip Pro Traction Systems are the latest design in traction using 3 x 2 spiral gear technology. These differentials provide smooth, dependable operation combining a limited-slip differential with the strength of a fully machined, forged steel case. Because there are no friction plates, no friction modifier additive is necessary. Always use a 80W-90 weight petroleum based gear oil with a GL-5 (or higher) rating, friction additive/modifiers should NOT BE USED. Synthetic oils and oils containing friction modifiers are not recommended.

Powertrax Grip Pro differentials are the ideal solution for just about any muscle car or truck on the road today. When you need that added traction so your muscle car puts power to the pavement instead of burning one wheel up, Powertrax Grip Pro limited slip differentials are your answer.

• Latest Posi-Trac Design
• Uses 3 x 2 Spiral Gear Technology
• Comes Fully Assembled
• Delivers Progressive and Variable Traction
• Allows You to Control How Much Traction is Applied
• Housed in a Fully Machined, Forged Steel Case

Proven Reliability

We run what we sell. Our third member units are the go-to choice for our own rides and we have built these units to last with high quality hardware and components. Tapered steel roller bearings minimize friction, better handle thrust loads and increase load carrying capacity. The ring gears are assembled with Grade 9 bolts with a tensile strength of 180,000 psi, a 15% increase over Grade 8 hardware. Heavy duty Grade 8 carrier cap bolts, a lock-style pinion nut with pre-applied Loctite and high-quality grade 5 pinion support bolts make our third member near-bulletproof.

Units include a Viton® pinion seal providing long lasting oil and chemical resistance. This seal retains elasticity up to 399°F (204°C) and intermittently up to 600°F (316°C) This high temp seal helps eliminate pinion leaks, reduces maintenance and keeps the third member properly lubricated. A carrier-to-housing gasket is available separately.

Our hand-assembled Ford 9 inch third member assemblies are made-to-order. We keep a supply of the most popular gears in stock, with most units built within 2-3 days. Our third-member units are shipped in a durable, reusable poly storage case, perfect for keeping multiple gear sets stored and ready for the track.
