Quaife Ford IB5 Dog Engagement Gearkit

Quaife dog engagement gearkit for Ford IB5 transmission

Quaife now offers an exciting transmission upgrade for users of the Ford IB5 gearbox fitted to the Ford Fiesta, Focus, Puma and Ka Mk1, which transforms the performance of these cars, for customers requiring a non-sequential transmission option.

Carrying part number QKE35Z, the gearkit is designed for easy installation into the standard Ford IB5 gearbox casing without modifications. Technical highlights include close-ratio, straight-cut gears to minimise transmission power losses and enable drivers to keep the engine working in its power band at all times. An open face dog design allows ultra fast gearshifts and QKE35Z includes a set of Quaife designed uprated gear selectors that ensure durability from the shift mechanism.

The combination of close-ratios, straight-cut gears and rapid dog engagement selection makes the QKE35Z IB5 5-speed gearkit the perfect choice for Ford owners seeking an advanced, reliable motorsport transmission solution. Quaife offers a choice of seven different final drive options, covering all potential motorsport, trackday and fast road use requirements.

Key technical features of the QKE35Z Ford IB5 5-speed dog engagement gearkit include:
- Open face dog engagement for rapid gear changes
- Straight-cut, close-ratio gears
- Installs into stock IB5 gear casing
- Quaife selector forks included in kit
- Includes heavy duty operating block for 3rd & 4th gear. Replaces standard sintered item, which is prone to breaking under high loads from dog engagement shifts
- Large choice of final drive ratios (QRE35Z)
- Heavy duty input shaft available for higher power applications. Uses Ford 1" x 23T clutch spline

The webshop price includes the basic gear kit. Most kits have options available and can for example be treated with the REM sperfinishing process. Please ask our sales for any questions and/or addons if you have anything on your mind!

REM Superfinishing

Upgrade your gearkit, gearbox or CWP with REM superfinishing to give a much smoother surface finish to the gears.

This high polish surface finish produces a smooth surface that not only allows for more even lubrication of the entire gear, but also reduces friction between meshing parts, thereby reducing heat and wear on the part, and increasing the longevity of your gearkit or gearbox.

This is an essential upgrade for anyone looking to improve the performance of their gearbox or differential and get the most from the transmission.

Gearkit and transmission types

H-Pattern

Synchromesh
Quaife's range of Clubman and heavy duty H-pattern synchromesh gearboxes retain the standard synchromesh engagement parts from the original gearboxes, and offer optimised gear ratios for motorsport to make the most of the power and torque from the engine in any given gear.

Dog Engagement
These are the next progression from a synchromesh gearbox, and are for those looking to decrease the time spent shifting gear by removing the necessity of operating the clutch for each gear change. Many of these dog boxes still use the same ratios as the synchromesh boxes.
The ability to shift gear without using the clutch reduces the time spent off the power and allows drivers to get back on the power sooner, resulting in faster overall race times.
Shifting with a dog box is different to a synchro box in that gear changes need to be fast and positive rather than slow and smooth.

Sequential

For those looking for the ultimate in fast gear changes, our range of sequential gearboxes is the logical progression from H-pattern gearboxes, offering ultra-fast gear changes through use of Quaife's proven drum change technology.
These sequential gearboxes are fully compatible with flat-shift ignition cut systems to allow full throttle gear changes, so unlike an H-pattern dog box, where lifting off the throttle is required, gear changes can be made with no noticeable interruption to power delivery.
