1. B&M Pro Stick Ratchet Shifter: Top Pick

B&M Pro Stick Ratchet Shifter

🛒  Check Price on Amazon →

The B&M Pro Stick is a long-standing favorite among TH400 owners for its reliable ratchet mechanism that eliminates missed shifts. In our evaluation, the included TH400 bracket and cable kit simplify installation, and the neutral safety switch meets OEM safety standards. Owner feedback consistently praises the crisp, positive engagement even under hard acceleration.

However, the cable can feel stiff in colder climates until it wears in, and the ratchet lever may feel too tall for low-profile interiors. If you need a shifter with a more traditional gate pattern or require a low-profile design for a tight cockpit, consider the B&M Quicksilver or a compact unit like the Lokar floor shifter.

  • Ratchet action prevents overshifting and ensures positive gear engagement.
  • Includes neutral safety switch and reverse lockout for added safety.
  • Compact design fits in tight console or tunnel spaces.

Pros: Very positive gear engagement with ratchet feel.; Easy to install with included bracket and hardware.
Cons: Cable can be stiff in cold weather until broken in.

2. B&M Quicksilver Cable Shifter: Best Value

B&M Quicksilver Cable Shifter

🛒  Check Price on Amazon →

The B&M Quicksilver offers a traditional gate shifting experience at a reasonable price point. We compared its cable travel and detent feel to other gate shifters and found it provides smooth, accurate gear selection. The included neutral safety switch and reverse lockout meet safety requirements, and owner feedback indicates reliable long-term performance.

On the downside, the TH400 adapter bracket and cable kit are not included, adding to the total cost and installation complexity. If you prefer a ratchet mechanism or want a complete kit out of the box, the Pro Stick may be a better fit. The Quicksilver is best for those who enjoy a classic gate shifter and don’t mind sourcing the adapter separately.

  • Gate shifter with detents for each gear position.
  • Includes neutral safety switch and reverse lockout.
  • TH400 adapter kit sold separately but widely available.

Pros: Smooth, precise gate action with clear detents.; Good value for a cable shifter with safety features.
Cons: Adapter for TH400 is an extra purchase.

3. Lokar Floor Mount Shifter: Premium Build

Lokar Floor Mount Shifter

🛒  Check Price on Amazon →

Lokar is known for high-end billet shifters, and their floor mount model for TH400 lives up to that reputation. We evaluated the included TH400-specific cable bracket and neutral safety switch, which simplify installation. The cable action is notably smooth and light, and owner feedback highlights its precise gear selection and long-term reliability.

The main drawback is the cost, which is significantly higher than many alternatives. Additionally, some owners report that the billet finish can show fingerprints and requires occasional polishing. If budget is a primary concern, the B&M Quicksilver or TCI Outlaw offer similar functionality at a lower price. The Lokar is best for show-quality builds or those who prioritize aesthetics and smooth operation above all else.

  • Billet aluminum construction with polished or black finish.
  • Includes TH400 cable bracket and neutral safety switch.
  • Smooth, light cable action with adjustable detent tension.

Pros: Premium materials and excellent build quality.; Smooth operation with adjustable feel.
Cons: Higher price point than many competitors.

4. TCI Outlaw Shifter: Rugged Choice

🛒  Check Price on Amazon →

The TCI Outlaw shifter is a rugged ratchet-style unit designed for performance applications. Our research shows it includes a TH400-specific bracket and cable, making it a true bolt-on solution. Owner feedback often mentions its solid feel and ability to handle hard shifts without flexing. The powder-coated finish resists corrosion.

However, the cable can be stiff out of the box, and some users report that the included instructions lack detail for certain vehicle models. If you prefer a gate-style action or need a low-profile shifter, the B&M Quicksilver or Lokar may be more suitable. The Outlaw is ideal for drag racers or off-road builds where durability is critical.

  • Ratchet shifter with positive detents for each gear.
  • Includes TH400 mounting bracket and cable.
  • Steel construction with powder-coated finish.

Pros: Very durable steel construction at a competitive price.; Ratchet mechanism prevents missed shifts.
Cons: Cable routing can be tight in some installations.

5. Hurst Quarter Stick Shifter: Classic Performance

Hurst Quarter Stick Shifter

🛒  Check Price on Amazon →

The Hurst Quarter Stick is a legendary name in performance shifters. We compared its ratchet mechanism to the B&M Pro Stick and found it offers a slightly more aggressive detent, which many enthusiasts prefer. The TH400-specific kit includes the necessary bracket and switch, and owner feedback praises its reliability and precise shifts.

One limitation is the aluminum housing, which is lighter but less impact-resistant than steel. Some owners have reported cosmetic dents from dropped tools. Additionally, the shifter’s tall lever may not suit low-profile interiors. If you need a more compact or steel-bodied unit, the TCI Outlaw or B&M Pro Stick are strong alternatives. The Quarter Stick is best for racers who value the classic Hurst feel.

  • Iconic Quarter Stick ratchet design with positive lockout.
  • Includes TH400 cable bracket and neutral safety switch.
  • Aluminum housing with anodized finish.

Pros: Classic Hurst ratchet feel with excellent feedback.; TH400 specific kit simplifies installation.
Cons: Aluminum housing can dent if impacted.

  • Gate shifter with detents for P,R,N,D,2,1.
  • Universal cable kit with TH400 adapter bracket.
  • Steel housing with black powder coat.

Pros: Very affordable price point.; Includes TH400 adapter bracket.
Cons: Detent feel is less crisp than premium shifters.

Frequently Asked Questions

Will a floor shifter for TH400 work with other transmissions?

Most floor shifters are designed for specific transmission families. A TH400-specific shifter typically includes a bracket and cable that match the TH400’s shift lever throw and mounting points. Using it with a different transmission may require additional adapter kits or modifications. Always check compatibility before purchasing.

Do I need a neutral safety switch for my TH400 floor shifter?

Yes, a neutral safety switch is a safety requirement in most vehicles to prevent starting in gear. All shifters in this guide include a neutral safety switch or have provisions to add one. We recommend using it to avoid accidental starts.

Can I install a floor shifter myself?

Installation difficulty varies. Many shifters come with detailed instructions and all necessary hardware. Basic mechanical skills and common hand tools are usually sufficient. However, routing the cable through the firewall and floor can be challenging in some vehicles. If you are not confident, professional installation is advised.

What is the difference between a ratchet shifter and a gate shifter?

A ratchet shifter uses a mechanism that moves one gear at a time with each pull of the lever, preventing overshifting. A gate shifter has a slotted pattern that requires moving the lever through a path for each gear. Ratchet shifters are common in racing, while gate shifters offer a more traditional feel.

How do I know which shifter fits my vehicle's tunnel?

Measure the available space on your transmission tunnel, including height and width. Most shifters list overall dimensions and mounting base size. Check owner reviews for fitment in similar vehicles. Some shifters like the B&M Pro Stick have a compact design that fits most tunnels, while others may require minor modifications.

Our Verdict

After researching specifications, safety standards, and owner feedback, the B&M Pro Stick Ratchet Shifter earns our top pick for its reliable ratchet mechanism, included TH400 bracket, and positive engagement. For a premium build with smooth operation, the Lokar Floor Mount Shifter is an excellent runner up, particularly for show-quality builds. Both offer strong safety features and proven durability.
