Frequently Asked Questions
The questions we are asked most often about S1 Sequential shift conversions, fitment, ordering and support. If your question is not answered here, contact us through the contact form.
Product and performance
Why convert to sequential shift?
An H-pattern is fine for everyday driving, but under the loads of hard acceleration and cornering, changing gears becomes much more demanding. Driveline rotation during the shift, when torque is interrupted, makes it harder again. A sequential shifter solves this with a simple pull back to shift up and push forward to shift down, with a direct motion that lets you feel exactly when the gear is engaged.
Will this be hard on the gearbox?
No. The design has been extensively tested to ensure it does not shorten the life of any gearbox component. Many customers report that the sequential shifter is easier on their gearbox because there are no missed shifts. The improvements you feel come from superior driver feedback and control.
How smooth is the shift?
The shifter moves with very high mechanical efficiency. In a shift there is very little force required except when the synchros are doing their work. Some designs mask this with rubber or springs, which creates a vague shift; the S1 shifter is direct and precise.
Do I still use the clutch?
Yes. It is your standard synchro gearbox with a bolt-on shifter, so you use the clutch for every shift as normal. Heel-and-toe and throttle blips work as they always have.
How is reverse selected?
The shift pattern is R-N-1-2-3-4-5-6. To select reverse you rotate the reverse lockout lever, then engage the gear. Reverse cannot be selected by accident. This mechanical lockout also allows the factory electronic lockout to be removed, which often simplifies clearance and wiring in conversions.
Where is neutral?
On every S1 shifter you can half-shift between any two gears to find a temporary neutral. The main neutral position depends on the kit: on the Ford Toploader, Muncie, G-Force T-101, Toyota R154, Nissan CD009 and Tremec TKX shifters it sits between 1st and 2nd; on the T56, Tr-6060 and Magnum shifters it sits below 1st.
Can I drive it on the street?
Many customers drive their cars daily with an S1 shifter fitted. The product is designed for motorsport and modified vehicles, and use on public roads may not be legal in every state or country, so please check the rules that apply to you.
Fitment
Is fitment easy? Can I do it myself?
Yes. Every kit is a bolt-on fitment that an enthusiast or mechanic can complete with standard tools. Written instructions and dimensioned drawings are supplied with each kit and are available on our Instructions and Technical Support page. Some classic cars may need the transmission tunnel trimmed for clearance; dimensions are published on the Shifter and Gearbox Dimensions page.
Which kit do I need?
Each product page lists the gearboxes and vehicles the kit fits and does not fit. If you are unsure, contact us with your vehicle, gearbox model and a photograph of the gearbox before you order and we will confirm fitment. Tremec owners can use the Tremec shifter selector.
Do you make a shifter for a gearbox not listed on the site?
No. Our current range is listed under Sequential Shifters and H-Pattern Shifters. We are unable to provide advice or support for gearboxes or products we do not sell.
Are new kits in development?
We continually develop new products but do not comment on unreleased designs or release dates. Announcements are made on our social channels.
Ordering and shipping
Can I return a kit if I change my mind or order the wrong one?
No. There are no refunds or exchanges for change of mind or incorrect selection. Every order is fulfilled exactly as placed, so please confirm fitment before ordering. See our Refund, Return and Repairs Policy.
How long does delivery take?
In-stock products are dispatched within 3 days of payment (up to 2 weeks during sale periods) and shipped worldwide by DHL Express. Shipping cost is shown at checkout; international customers are responsible for duties and local taxes. See Shipping Information.
When will an out-of-stock kit be available?
Demand and manufacturing lead times mean some kits are periodically out of stock. We do not take back orders. Follow our social channels to be notified when stock returns.
Warranty and support
What warranty applies?
All products carry a 1-year warranty to the original purchaser from the date of purchase. Replacement and spare parts are available beyond the warranty period. Full terms are on the Product Warranty page.
How do I get technical support?
Technical support is available to original purchasers through the contact form. Please include your order number, a description of the issue and photographs of the gearbox and shifter so we can help quickly.
