Axle U bolts are often overlooked when modifying a RWD car. The U-bolt’s job is to connect the axle to the leaf springs. Most aftermarket U-bolts are fine for standard cars but as soon as they are used aggressively or with cars with more BHP they have a tendency to stretch and bed in and will need to be re-tightened periodically. The 4 main issues of most aftermarket U-bolts are choice of material, thread size, bend radius accuracy and lack of flat on the bend radius.
Retroford has developed an uprated U-bolt to combat all these issues.
They feature:
: Oversize 12mm thread (but still fit std leaf spring retaining plate).
: Hot forged to create a flat face where the underside of the U-bolt meets the axle tube gives far more surface area and a more positive axle location.
: Made from high tensile steel.
: Accurate bend radius.
: Comes with nuts and washer.
: Can be used with Retroford heavy-duty rear leaf spring plates (DRT040*B) and also Retroford diff nose axle correction wedges.
: Sold as axle an axle set = 4 x bolt U-bolts, 8 x washers .8 x nuts.
: Available exclusively from Retroford.
: Can be used without lowering blocks or a maximum of 1” lowering blocks.
: Not suitable for 2” lowering blocks.
