1954 vs 1956 Shifter Base Bushings: Fitment and Trade-offs

1954 and 1956 shifter base bushings use the same solid-aluminum design but fit different Hondas and Acuras. Match the part to your chassis before you buy.
Quick answer
Choose 1954 or 1956 based on your exact chassis, not on price or shift feel—both replace the OEM rubber base bushings with solid aluminum and Class 10.9+ hardware. If your car is listed for both, pick the one that matches your model year and verify the base shape before ordering.
The real difference is fitment, not materials
The 1954 and 1956 share the same core construction: solid aluminum bushings, Class 10.9+ hardware, a purple anodized finish, and laser-etched driver and torque specs. The catalog does not list vehicle applications, so the deciding factor is whether the bushing shape and hardware match your shifter base. Treat the part number as a chassis-specific key, not a performance tier.
What you give up with solid aluminum
Replacing compliant rubber with solid aluminum removes the cushion that absorbs vibration and road noise. You get a more direct, consistent shift feel and less shifter flex under load, but you should expect more vibration and gear whine to reach the cabin. That is the trade-off: precision and durability in exchange for comfort.
Price is a tiebreaker, not a guide
At catalog prices, the 1956 is listed lower than the 1954, but the difference is small and should not drive your decision. Buying the wrong bushing because it costs less means returns, downtime, or a part that will not seat correctly. Confirm fitment first, then let price decide only if both numbers are valid for your car.
Trade-offs to weigh before you buy
- Chassis fitment: The 1954 and 1956 are not interchangeable by price or appearance. Check your model and year against the part number, and if you are unsure, measure the OEM bushing or contact support before ordering. Fitment is the only non-negotiable criterion.
- Shift feel vs. cabin comfort: Both bushings remove rubber compliance, which sharpens shift feel and reduces flex. The cost is more noise and vibration. If your car is a daily driver on rough roads, decide whether that trade-off is acceptable before you commit. Solid aluminum is a performance choice, not a comfort upgrade.
- Installation effort: Both require access to the shifter base and torqueing hardware to the etched specs. The 1954 and 1956 use the same style of hardware, so installation difficulty is similar—plan for the same labor either way. Budget the same time and tools for either part.
Product facts
- 1954 Shifter Base Bushings: Solid aluminum construction with Class 10.9+ hardware and laser-etched driver and torque specs. You get the hardware and torque guidance needed for a precise install, but the solid material transmits more vibration than rubber.
1954 Shifter Base Bushings - 1956 Shifter Base Bushings: Same solid-aluminum design and purple anodized finish as the 1954, with a lower catalog price. If it fits your chassis, it delivers the same reduction in shifter flex for less money—but only if the fitment is correct.
1956 Shifter Base Bushings
Which one should you choose?
Choose 1954 if:
- Your chassis is explicitly listed for the 1954 part number.
- You want the exact bushing set engineered for that application.
Choose 1956 if:
- Your chassis is explicitly listed for the 1956 part number.
- You are not sure the 1954 fits and the 1956 is confirmed for your car.
