The TRANS-DAPT 7106 is a universal 4 lug wheel spacer built to gain disc brake clearance when fitting custom wheels to rear-wheel-drive vehicles. It fits 4.0 in., 4.25 in., and 4.50 in. bolt circle diameters with a 2.75 in. center hole, so one part number covers several common 4-lug patterns. Drivers running aftermarket rims often find the disc brake caliper or hub geometry pushes the wheel out of position, and this spacer moves the rim outboard far enough to clear. It ships as a pair, one spacer per wheel. See more options in our wheels and tires selection.
Each spacer is machined from aluminum, which keeps rotating mass low compared to a steel adapter of the same footprint. The 7106 carries a 6.00 in. outer diameter, giving the wheel face full support across the bolt circle, and the 2.75 in. center bore accommodates the hub register on most rear-wheel-drive disc brake setups. Thickness specs run between 1/4 in. and 5/16 in. depending on the production run. Because the spacer adds material between the hub face and the wheel, installation may require longer wheel studs to maintain full thread engagement. The universal bolt circle design means the same part services 4.0, 4.25, and 4.50 in. patterns without separate SKUs for each. Pair it with the right rims from our wheel catalog.
This spacer suits street and show builds where custom wheels need a touch more clearance over the disc brake assembly, particularly classic American rear-wheel-drive cars. Per the manufacturer, it is not intended for trucks, front-wheel-drive vehicles, or competition use. Before ordering, confirm your bolt circle falls within the 4.0 to 4.50 in. range and check that you have studs long enough for the added thickness. If you need a larger offset adjustment, look at our dedicated wheel spacers, or browse the full wheels and tires department for matching hardware and accessories.
Frequently Asked Questions
What bolt patterns does the TRANS-DAPT 7106 fit?
The 7106 is a universal 4-lug spacer that fits 4.0 in., 4.25 in., and 4.50 in. bolt circle diameters. It uses a 2.75 in. center hole and a 6.00 in. outer diameter, so one part covers several common 4-lug rear-wheel-drive patterns.
How thick is this spacer?
Listed thickness runs between 1/4 in. (0.250 in.) and 5/16 in. depending on the production run. Either way, the added material moves the wheel outboard for disc brake clearance, so plan to verify your stud length before installation.
Do I need longer wheel studs to install it?
Often, yes. Because the spacer adds thickness between the hub face and the wheel, your existing studs may not provide full thread engagement once the spacer is in place. Confirm you have studs long enough to safely seat the lug nuts.
Is the 7106 sold individually or as a pair?
It ships as a pair, with one spacer per wheel. That covers both wheels on a single axle when you are setting up custom rims that need additional disc brake clearance.
Can I use this on a truck or front-wheel-drive car?
No. Per the manufacturer, the 7106 is intended for rear-wheel-drive vehicles with disc brakes and custom wheels. It is not designed for trucks, front-wheel-drive vehicles, or competition use.
